RESUMO

PURPOSE: to know the family interaction with the hearing impaired child/adolescent. METHODS: descriptive and exploratory qualitative research developed at a Special School in Southern Brazil. Participants were 10 primary caregivers of deaf children/adolescents between 10 and 19 years old. The collection took place in November 2017, through semi-structured interviews containing questions about the communication process of deaf children/adolescents with their families. The information was analyzed through thematic analysis. The study was submitted and approved by the Ethics Committee under opinion number 2.333.560. RESULTS: as the main theme of the study "Interaction between the family and the child/adolescent with hearing impairment", it addresses two sub-themes: potentialities and weaknesses in the communication of the family with the child/adolescent with hearing impairment and learning in the care of the child/adolescent with hearing impairment. CONCLUSION: it was identified that the interaction of the deaf with the family and society is impaired by people's lack of knowledge about the deaf community and the Brazilian Sign Language, which raises concern in caregivers who often overprotect the child/adolescent which may limit the full development of their skills and autonomy.

RESUMO

Acoustic communication is enabled by the evolution of specialised hearing and sound producing organs. In this study, we performed a large-scale macroevolutionary study to understand how both hearing and sound production evolved and affected diversification in the insect order Orthoptera, which includes many familiar singing insects, such as crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly establish phylogenetic relationships among the major lineages and divergence time estimates within Orthoptera, as well as the lineage-specific and dynamic patterns of evolution for hearing and sound producing organs. In the suborder Ensifera, we infer that forewing-based stridulation and tibial tympanal ears co-evolved, but in the suborder Caelifera, abdominal tympanal ears first evolved in a non-sexual context, and later co-opted for sexual signalling when sound producing organs evolved. However, we find little evidence that the evolution of hearing and sound producing organs increased diversification rates in those lineages with known acoustic communication.

RESUMO

Bone-conducted ultrasound (BCU) is perceived even by the profoundly sensorineural deaf and has been applied to the development of a novel hearing aid. In the BCU hearing aid, the vibrator is pressed onto the mastoid process of the temporal bone (the osseous bulge behind the ear). However, BCU can be heard on distal parts of the body; e.g., the muscle of the neck, the clavicle and the upper limbs. Some studies have been carried out to develop other BCU hearing devices using this "distant presentation". However, the possibility of the localization of distantly-presented BCU has not been verified. In this study, we investigated whether listeners could use the interaural time differences (ITDs) and intensity differences (IIDs) as cues for lateralization (left/right discrimination) of distantly-presented BCU. The results showed that lateralization based on ITDs and IIDs is possible to some extent, even for the distant presentation, whereas lateralization become difficult as the stimulus placement gets further from the head. Lateralization based on IIDs was more accurate than that based on ITDs. IIDs seem to give more effective cues than ITDs in the lateralization of BCU.

RESUMO

Reverberation reduces speech quality, and therefore causes inconveniency to listeners, especially those using assistive hearing devices. To enhance the quality of reverberant speech, a significant step is speech quality assessment, most of which are based on subjective judgements. Subjective evaluations vary with listeners' perception, emotional and mental states. To obtain an objective assessment of speech quality in reverberation, this work carried out an event related potential (ERP) study using a passive oddball paradigm. Listeners were presented with anechoic speech as standard stimuli mixed with reverberant speech under different levels of reverberation as deviant stimuli. The ERP responses reveal how human-beings' subconsciousness interacts with different levels of reverberation in the perceived speech. Results showed that the peak amplitude of P300 in ERP responses followed the variation of reverberation time in reverberant speech, providing evidence that P300 in ERP responses could work as a neural surrogate of reverberation time in objective speech quality assessment.

RESUMO

Effective hearing aid (HA) rehabilitation requires personalization of the HA fitting parameters, but in current clinical practice only the gain prescription is typically individualized. To optimize the fitting process, advanced HA settings such as noise reduction and microphone directionality can also be tailored to individual hearing deficits. In two earlier studies, an auditory test battery and a data-driven approach that allow classifying hearing-impaired listeners into four auditory profiles were developed. Because these profiles were found to be characterized by markedly different hearing abilities, it was hypothesized that more tailored HA fittings would lead to better outcomes for such listeners. Here, we explored potential interactions between the four auditory profiles and HA outcome as assessed with three different measures (speech recognition, overall quality, and noise annoyance) and six HA processing strategies with various noise reduction, directionality, and compression settings. Using virtual acoustics, a realistic speech-in-noise environment was simulated. The stimuli were generated using a HA simulator and presented to 49 habitual HA users who had previously been profiled. The four auditory profiles differed clearly in terms of their mean aided speech reception thresholds, thereby implying different needs in terms of signal-to-noise ratio improvement. However, no clear interactions with the tested HA processing strategies were found. Overall, these findings suggest that the auditory profiles can capture some of the individual differences in HA processing needs and that further research is required to identify suitable HA solutions for them.

RESUMO

The presence of additional disabilities (AD) in children with sensorineural hearing loss (SNHL) and influence of AD on age of hearing loss diagnosis and amplification were investigated. It was shown that 41% children with SNHL have different AD - pathology of the central neural system (including mental retardation, autism spectrum disorders, attention deficits), vision, motor and articulation impairments, cardiovascular, respiratory, urinary, digestive, endocrine diseases etc. 59% children among them have 2-3 AD. The most often combination of AD was pathology of central neural and motor systems. The genetic factor was revealed rarely in the group of children with AD than in children with SNHL only. The diagnosis of hearing loss before age 4 months was rarely in the group of children with AD. Possibly it is because of the most of such children got treatment in neonatal intensive care unit and didn't have access to universal newborn hearing screening. Moreover, SNHL might develop later as the outcome of their AD or their treatment. Suggestion about more late amplification in children with SNHL was confirmed. The cause might be wary relation of audiologists to amplification of children with AD and difficulties of this process.

RESUMO

BACKGROUND: Hearing loss and tinnitus are global concerns that can be reduced through hearing protection behaviors (e.g., earplug use). Little is known about the effectiveness of interventions to increase hearing protection use in recreational domains. For the first time we review systematically the effectiveness of such interventions. METHODS: Systematic searches of nine databases, as well as grey literature and hand-searching, were conducted. Any study design was included if it assessed quantitatively a purposeful attempt to increase hearing protection in recreational settings. Studies were excluded if they assessed noise exposure from occupational sources and headphones/earphones, as these have been reviewed elsewhere. PROSPERO protocol: CRD42018098573. RESULTS: Eight studies were retrieved following the screening of 1908 articles. Two pretest-posttest studies detected a small to medium effect (d ≥ 0·3 ≤ 0·5), one a small effect (d ~ =0·2) and two no real effect. Three posttest experimental studies detected small to medium effects (d ≥ 0·3 ≤ 0·5). Studies were rated as "poor quality" and 17 out of a possible 93 behavior change techniques were coded, with the majority targeting the intervention function 'education'. CONCLUSIONS: Hearing loss and tinnitus due to recreational noise exposure are major public health concerns yet very few studies have examined preventive interventions. The present systematic review sets the agenda for the future development and testing of evidence-based interventions designed to prevent future hearing loss and tinnitus caused by noise in recreational settings, by recommending systematic approaches to intervention design, and implementation of intervention functions beyond education, such as incentivization, enablement and modeling.

RESUMO

Recently diverged taxa with contrasting phenotypes offer opportunities for unravelling the genetic basis of phenotypic variation in nature. Horseshoe bats are a speciose group that exhibit a derived form of high-duty cycle echolocation in which the inner ear is finely tuned to echoes of the narrowband call frequency. Here, by focusing on three recently diverged subspecies of the intermediate horseshoe bat (Rhinolophus affinis) that display divergent echolocation call frequencies, we aim to identify candidate loci putatively involved in hearing frequency variation. We used de novo transcriptome sequencing of two mainland taxa (himalayanus and macrurus) and one island taxon (hainanus) to compare expression profiles of thousands of genes. By comparing taxa with divergent call frequencies (around 15 kHz difference), we identified 252 differentially expressed genes, of which six have been shown to be involved in hearing or deafness in human/mouse. To obtain further validation of these results, we applied quantitative reverse transcription-PCR to the candidate gene FBXL15 and found a broad association between the level of expression and call frequency across taxa. The genes identified here represent strong candidate loci associated with hearing frequency variation in bats.

RESUMO

BACKGROUND: Meniere's disease (MD) is a chronic condition of the inner ear consisting of symptoms that include vertigo attacks, fluctuating sensorineural hearing loss, tinnitus and aural fullness. Despite availability of various interventions, there is uncertainty surrounding their relative efficacy, thus making it difficult to select the appropriate treatments for MD. The objective of this systematic review was to assess the relative effects of the available pharmacologic and surgical interventions in patients with MD with regard to vertigo and other key patient outcomes based on data from randomized clinical trials (RCTs). METHODS: Our published protocol registered with PROSPERO (CRD42019119129) provides details on eligibility criteria and methods. We searched various databases including MEDLINE, Embase and the Cochrane Library from inception to December 10th, 2018. Screening at citation and full-text levels and risk of bias assessment were performed by two independent reviewers in duplicate, with discrepancies resolved by consensus or third-party adjudication. Bayesian network meta-analyses (NMA) were performed for hearing change and vertigo control outcomes, along with pairwise meta-analyses for these and additional outcomes. RESULTS: We identified 2,889 unique citations, that yielded 23 relevant publications describing 18 unique RCTs (n = 1,231 patients). Overall, risk-of bias appraisal suggested the evidence base to be at unclear or high risk of bias. Amongst pharmacologics, we constructed treatment networks of five intervention groups that included placebo, intratympanic (IT) gentamicin, oral high-dose betahistine, IT steroid and IT steroid plus high-dose betahistine for NMAs of hearing change (improvement or deterioration) and complete vertigo control. IT steroid plus high-dose betahistine was associated with the largest difference in hearing improvement compared to placebo, followed by high-dose betahistine and IT steroid (though 95% credible intervals failed to rule out the possibility of no difference), while IT gentamicin was worse than IT steroid. The NMA of complete vertigo control suggested IT gentamicin was associated with the highest probability of achieving better complete vertigo control compared to placebo, followed by IT steroid plus high-dose betahistine. Only two studies related to surgical interventions were found, and data suggested no statistically significant difference in hearing changes between endolymphatic duct blockage (EDB) versus endolymphatic sac decompression (ESD), and ESD with or without steroid injection. One trial reported that 96.5% of patients in EDB group compared to 37.5% of the patients in ESD group achieved complete vertigo control 24 months after surgery (p = 0.002). CONCLUSION: To achieve both hearing preservation and vertigo control, the best treatment option among the pharmacologic interventions compared may be IT steroid plus high-dose betahistine, considering that IT gentamicin may have good performance to control vertigo but may be detrimental to hearing preservation with high cumulative dosage and short interval between injections. However, IT steroid plus high-dose betahistine has not been compared in head-to-head trials against other interventions except for IT steroid alone in one trial, thus future trials that compare it with other interventions will help establish comparative effectiveness with direct evidence.

RESUMO

Hearing aids are an effective treatment for individuals with hearing loss that have been shown to dampen (and sometime ameliorate) the negative effects of hearing loss. Despite the devices' efficacy, many reject hearing aids as a form of treatment. In the present qualitative study, we explored the reasons for hearing aid non-use in the United States that emerged from the stories of adults with hearing loss who do not to utilize hearing aids. We specifically used thematic analysis in concert with an attribution theory framework to identify and analyze recurring themes and reasons throughout these individuals' narratives. A total of nine themes describing reasons of hearing aid non-use emerged. Four reasons were internally motivated: (1) non-necessity, (2) stigmatization, (3) lack of integration into daily living, and (4) unreadiness due to lack of education; five reasons were externally motivated: (5) discomfort, (6) financial setback, (7) burden, (8) professional distrust, and (9) priority setting. These findings contribute to the field of hearing healthcare by providing professionals with insight into reasons that people across the provided when recounting their experiences following the diagnosis of hearing loss, prescription for hearing aids, and their hearing aid non-use. These findings are an important step toward the development of more effective, person-centered hearing healthcare that can best address these individuals' concerns and expectations surrounding hearing loss and hearing aids.

RESUMO

Previous research on inattentional blindness (IB) has focused almost entirely on the visual modality. This study extends the paradigm by pairing visual with auditory stimuli. New visual and auditory stimuli were created to investigate the phenomenon of inattention in visual, auditory, and paired modality. The goal of the study was to assess to what extent the pairing of visual and auditory modality fosters the detection of change. Participants watched a video sequence and counted predetermined words in a spoken text. IB and inattentional deafness occurred in about 40% of participants when attention was engaged by this difficult (auditory) counting task. Most importantly, participants detected the changes considerably more often (88%) when the change occurred in both modalities rather than just one. One possible reason for the drastic reduction of IB or deafness in a multimodal context is that discrepancy between expected and encountered course of events proportionally increases across sensory modalities.

RESUMO

It is well known that hearing loss compromises auditory scene analysis abilities, as is usually manifested in difficulties of understanding speech in noise. Remarkably little is known about auditory scene analysis of hearing-impaired (HI) listeners when it comes to musical sounds. Specifically, it is unclear to which extent HI listeners are able to hear out a melody or an instrument from a musical mixture. Here, we tested a group of younger normal-hearing (yNH) and older HI (oHI) listeners with moderate hearing loss in their ability to match short melodies and instruments presented as part of mixtures. Four-tone sequences were used in conjunction with a simple musical accompaniment that acted as a masker (cello/piano dyads or spectrally matched noise). In each trial, a signal-masker mixture was presented, followed by two different versions of the signal alone. Listeners indicated which signal version was part of the mixture. Signal versions differed either in terms of the sequential order of the pitch sequence or in terms of timbre (flute vs. trumpet). Signal-to-masker thresholds were measured by varying the signal presentation level in an adaptive two-down/one-up procedure. We observed that thresholds of oHI listeners were elevated by on average 10 dB compared with that of yNH listeners. In contrast to yNH listeners, oHI listeners did not show evidence of listening in dips of the masker. Musical training of participants was associated with a lowering of thresholds. These results may indicate detrimental effects of hearing loss on central aspects of musical scene perception.

RESUMO

Sound externalization, or the perception that a sound source is outside of the head, is an intriguing phenomenon that has long interested psychoacousticians. While previous reviews are available, the past few decades have produced a substantial amount of new data.In this review, we aim to synthesize those data and to summarize advances in our understanding of the phenomenon. We also discuss issues related to the definition and measurement of sound externalization and describe quantitative approaches that have been taken to predict the outcomes of externalization experiments. Last, sound externalization is of practical importance for many kinds of hearing technologies. Here, we touch on two examples, discussing the role of sound externalization in augmented/virtual reality systems and bringing attention to the somewhat overlooked issue of sound externalization in wearers of hearing aids.

RESUMO

The benefit in speech-recognition performance due to the compensation of a hearing loss can vary between listeners, even if unaided performance and hearing thresholds are similar. To accurately predict the individual performance benefit due to a specific hearing device, a prediction model is proposed which takes into account hearing thresholds and a frequency-dependent suprathreshold component of impaired hearing. To test the model, the German matrix sentence test was performed in unaided and individually aided conditions in quiet and in noise by 18 listeners with different degrees of hearing loss. The outcomes were predicted by an individualized automatic speech-recognition system where the individualization parameter for the suprathreshold component of hearing loss was inferred from tone-in-noise detection thresholds. The suprathreshold component was implemented as a frequency-dependent multiplicative noise (mimicking level uncertainty) in the feature-extraction stage of the automatic speech-recognition system. Its inclusion improved the root-mean-square prediction error of individual speech-recognition thresholds (SRTs) from 6.3 dB to 4.2 dB and of individual benefits in SRT due to common compensation strategies from 5.1 dB to 3.4 dB. The outcome predictions are highly correlated with both the corresponding observed SRTs (R2 = .94) and the benefits in SRT (R2 = .89) and hence might help to better understand-and eventually mitigate-the perceptual consequences of as yet unexplained hearing problems, also discussed in the context of hidden hearing loss.

RESUMO

It is of clinical interest to estimate pure-tone thresholds from potentially available objective measures, such as stimulus-frequency otoacoustic emissions (SFOAEs). SFOAEs can determine hearing status (normal hearing vs. hearing loss), but few studies have explored their further potential in predicting audiometric thresholds. The current study investigates the ability of SFOAEs to predict hearing thresholds at octave frequencies from 0.5 to 8 kHz. SFOAE input/output functions and pure-tone thresholds were measured from 230 ears with normal hearing and 737 ears with sensorineural hearing loss. Two methods were used to predict hearing thresholds. Method 1 is a linear regression model; Method 2 proposed in this study is a back propagation (BP) network predictor built on the bases of a BP neural network and principal component analysis. In addition, a BP network classifier was built to identify hearing status. Both Methods 1 and 2 were able to predict hearing thresholds from 0.5 to 8 kHz, but Method 2 achieved better performance than Method 1. The BP network classifiers achieved excellent performance in determining the presence or absence of hearing loss at all test frequencies. The results show that SFOAEs are not only able to identify hearing status with great accuracy at all test frequencies but, more importantly, can predict hearing thresholds at octave frequencies from 0.5 to 8 kHz, with best performance at 0.5 to 4 kHz. The BP network predictor is a potential tool for quantitatively predicting hearing thresholds, at least at 0.5 to 4 kHz.

RESUMO

BACKGROUND: For patients with single-sided deafness (SSD), restoration of binaural function via cochlear implant (CI) has been shown to improve speech understanding in noise. The objective of this study was to investigate changes in behavioral performance and cortical auditory responses following cochlear implantation. DESIGN: Prospective longitudinal study. SETTING: Tertiary referral center. METHODS: Six adults with SSD were tested before and 12 months post-activation of the CI. Six normal hearing (NH) participants served as experimental controls. Speech understanding in noise was evaluated for various spatial conditions. Cortical auditory evoked potentials were recorded with /ba/ stimuli in quiet and in noise. Global field power and responses at Cz were analyzed. RESULTS: Speech understanding in noise significantly improved with the CI when speech was presented to the CI ear and noise to the normal ear (p<0.05), but remained poorer than that of NH controls (p<0.05). N1 peak amplitude measure in noise significantly increased after CI activation (p<0.05), but remained lower than that of NH controls (p<0.05) at 12 months. After 12 months of CI experience, cortical responses in noise became more comparable between groups. CONCLUSION: Binaural restoration in SSD patients via cochlear implantation improved speech performance noise and cortical responses. While behavioral performance and cortical auditory responses improved, SSD-CI outcomes remained poorer than that of NH controls in most cases, suggesting only partial restoration of binaural hearing.

RESUMO

The aim of this study was to investigate the prevalence of tinnitus among adolescents, and the factors known or hypothesized to be associated with tinnitus. Based on random sampling of school types and regions, a nationwide hearing survey of the first-year middle and high school students of South Korea was performed. The subjects underwent an otologic examination followed by pure tone audiometry up to 8 kHz. Questionnaires about the factors associated with hearing and tinnitus were completed by the students and their parents. Among the 1,593 subjects who completed the questionnaire and underwent pure tone audiometry, the prevalence of tinnitus was 46.0% and that of severe tinnitus was 9.1%. Tinnitus was associated with age, female gender, history of ear infection and sinusitis, leisure noise exposure due to karaoke and local-area-network gaming, alcohol consumption, and cigarette smoking. Noticeable hearing loss was not detected but participants with tinnitus complained of difficulty with sound localization, hearing in noise, and verbal working memory and were more susceptible to fatigue. The subjects with tinnitus also suffered more physical and mental health problems than did those without tinnitus. Thus, protection of the ears from noise and appropriate counseling should be considered for adolescents with tinnitus.

RESUMO

Objective:To evaluate the cognitive function of patients with presbycusis, and to explore the relationship among age, hearing loss, speech recognition ability and cognitive function. Method:A total of 131 elder participated in this study. Based on hearing threshold, all participants were divided into the elderly hearing loss group(66 cases) and the control group(65 cases with normal hearing). ① The pure tone audiometry test was completed to obtain the average hearing threshold of 0.5, 1, 2, and 4 kHz; ② The single-syllable vocabulary in Mandarin Speech Test Materials was used to test the maximum speech recognition rate and the speech recognition rate at 60 dB HL in a quiet environment about the better ear; ③ Chinese version of the Mini-mental State Examination(MMSE) was used to assess the subject's cognitive function; ④ Use spearman correlation coefficient to analyze the correlation between age, average hearing threshold, maximum speech recognition rate and the MMSE score; ⑤ Use GLM to analyze the effects of gender, deafness time, and education level on the cognitive function in presbycusis patients. Result:① The proportion of mild cognitive dysfunction(<27 points)(16.7%) in the elderly hearing loss group was higher than the control group(10.8%), but there was no significant difference(P>0.05); ②The MMSE score decreased with age(P<0.05), and there was a significant correlation between MMSE score and age(the control group: r=-0.424, P=0.000; the elderly hearing loss group: r=-0.277, P=0.024); ③There was a significant difference in MMSE scores between groups with different average hearing threshold levels(P<0.05), and there was a significant correlation between the MMSE score and the average hearing threshold in the elderly hearing loss group(r=-0.375, P<0.01); ④The MMSE score of the elderly hearing loss group with a low speech recognition rate at 60 dB HL(<50%) was significantly lower than the group with a high speech recognition rate(≥50%), and there was a significant correlation between MMSE score and maximum speech recognition rate(r=0.402, P=0.001); ⑤The average age and hearing threshold of the MCI in the elderly hearing loss group were significantly higher than the normal cognitive function group(27-30 points)(P<0.05), and the average maximum speech recognition rate was significantly lower than the normal cognitive function group(P<0.05); ⑥Analyzed by the GLM, the deafness time and education level have significant effects on MMSE scores(ß=-0.066, t=-2.98, P<0.01; ß=0.286 9, t=2.39, P<0.05), but gender have no significant effect on MMSE scores(ß=0.277, t=1.46, P=0.143). Conclusion:The age, hearing loss and speech recognition ability of presbycusis patients was significantly correlated with cognitive function. The incidence rate of MCI in presbycusis patients is higher than that in elderly normal hearing subjects. Deafness time is a risk factor of mild cognitive impairment, while education is a protective factor.

RESUMO

Objective:To compare the efficacy of cochlear implantation in deaf patients with Mondini malformation and normal anatomical structure of inner ear, and to determine whether cochlear implantation can be an effective way to reconstruct hearing in hearing loss patients with Mondini malformation, so as to guide clinical work. Method:Literature search was conducted on PubMed, YZ365. com, Wip medicine, Wanfang data, CHKD, CNKI and other electronic databases to search case control studies on postoperative rehabilitation effect of deafness patients with Mondini deformity and normal structure of inner ear. Execute Meta-analysis by using RevMan 5.3 software. Result:Eleven articles were included and 1 371 patients were involved. Meta-analysis showed that the probability of Mondini abnormalities in patients with intraoperative complications(Z=6.62, P<0.01), electrode reaction T value(Z=6.08, P<0.01), postoperative hearing threshold(500 Hz, 1 000 Hz and 2 000 Hz) is greater than the control group, neural response telemetry(Z=3.44, P<0.01) and categories of auditory performance score(Z=5.27, P<0.01) is lower than the control group, about postoperative complications(Z=1.01, P>0.05) and speech intelligibility rating score(Z=1.41, P>0.05) there was no statistically significant difference with the control group. Conclusion:Cochlear implantation can be a mean of treatment and rehabilitation for deafness patients with Mondini deformity, and is necessary for hearing reconstruction. Further multi-parameter controlled studies with longer follow-up periods and larger samples will increase the credibility for the efficacy of cochlear implants in deafness patients with Mondini malformation.

RESUMO

PURPOSE: To evaluate the ability that in tune and out of tune individuals have to identify normal and deviated voice qualities and to compare it with their performance in auditory processing tests and perceptual judgment. METHOD: The study investigated 15 in tune and 15 out of tune individuals. Participants were matched for age and sex, were amateur choir singers, had normal hearing thresholds and normal vocal quality. All individuals underwent Pitch-matching scanning to be classified as in or out of tune. Next, they performed the Pitch Pattern Sequence (PPS) and the Duration Pattern Sequence (DPS) tests and the perceptual judgment of 36 voices plus 20% of repetition for reliability analysis. RESULTS: The out of tune individuals had worse performance in the PPS and DPS for both ears (p=0.002 RE; p=0.001 LE; p=0.009 DPS); no difference was observed in the perceptual judgment and the reliability (p=0.153). However, participants with normal PPS and DPS had better performance in the perceptual judgment and better reliability (p=0.033). Thus, individuals with disorders in temporal auditory processing skills have greater difficulty in the perceptual judgment and have lower intra-rater reliability, despite being in or out of tune. CONCLUSION: It can be observed that voice tone is not required to guarantee good perceptual judgment. However, temporal patterns and intra-rater reliability are essential to perceptually assess normal and altered voice qualities. Therefore, auditory training should be included in programs that aim to develop voice perceptual judgment abilities.
