The relationship between age, acceptable noise level, and listening effort in middle-aged and older-aged individuals.

Objective: The purpose of the study was to evaluate listening effort in adults who experience varied annoyance towards noise. Materials and methods: Fifty native Kannada-speaking adults aged 41-68 years participated. We evaluated the participant's acceptable noise level while listening to speech. Further, a sentence-final word-identification and recall test at 0 dB SNR (less favorable condition) and 4 dB SNR (relatively favorable condition) was used to assess listening effort. The repeat and recall scores were obtained for each condition. Results: The regression model revealed that the listening effort increased by 0.6% at 0 dB SNR and by 0.5% at 4 dB SNR with every one-year advancement in age. Listening effort increased by 0.9% at 0 dB SNR and by 0.7% at 4 dB SNR with every one dB change in the value of Acceptable Noise Level (ANL). At 0 dB SNR and 4 dB SNR, a moderate and mild negative correlation was noted respectively between listening effort and annoyance towards noise when the factor age was controlled. Conclusion: Listening effort increases with age, and its effect is more in less favorable than in relatively favorable conditions. However, if the annoyance towards noise was controlled, the impact of age on listening effort was reduced. Listening effort correlated with the level of annoyance once the age effect was controlled. Furthermore, the listening effort was predicted from the ANL to a moderate degree.

Objective Measure of Listening Effort in HearingImpaired Individuals With and Without Tinnitus.

BACKGROUND: Tinnitus is a perception of sound in the brain without any external stimulus. Tinnitus patients often complain of more efforts required in listening. They may be ineffective in inhibiting their attention, driven to irrelevant ringing sounds in their ear rather than attending to the relevant target speech stimulus. The study's objective was to evaluate an allocation of cognitive resources among tinnitus patients for concurrent tasks required for understanding speech using an objective dual-task paradigm to assess listening effort. METHODS: We recruited 40 participants with mild to moderately severe sloping sensorineural hearing loss within 60-70 years. They were subgrouped into control and clinical groups. The clinical group had a severe degree of tonal tinnitus bilaterally. The objective listening task used listening effort, and a subjective questionnaire to assess the effort in listening was assessed by each study participant. RESULTS: The results indicated poorer recognition and reduced recall scores in a clinical group than the control group in each signal-to-noise ratio. The recall score in objective listening effort measurement was strongly correlated with subjective questions assessed effort in listening among the clinical group at each signal-to-noise ratio. However, in the control group, the correlation was to a mild degree at 0 dB signal-to-noise ratio only. CONCLUSION: Annoyance caused by tinnitus disrupts attention, thereby limiting the effective use of cognitive resources for concurrent speech processing and recalling reflected in the listening effort task.

Quality of life in parents of children with Autism spectrum disorder: Emphasizing challenges in the Indian context.

Purpose: Research has raised concerns about the quality of life (QOL) of parents of children with Autism spectrum disorder (ASD). Parents in different cultures show different psychological functioning when caring for a child with ASD. Hence, we examined QOL in parents of children with ASD in India and its relationship with socio-demographic factors. Materials and methods: We used a self-reported questionnaire and WHOQOL-BREF instrument to collect data on socio-demographic details and QOL respectively. Data were collected from two groups of participants - parents of children with ASD and parents of typically developing children (N = 60). Results: Results revealed significant differences in QOL between the two groups. Further, we found a positive correlation between socio-demographic variables and QOL in parents of children with ASD. Conclusions: Findings emphasize the need for intervention approaches aimed at family functioning, improving support services, and assisting parents to develop healthy coping strategies.

Effect of compression release time of a hearing aid on sentence recognition and the quality judgment of speech.

CONTEXT: The sentence recognition score and quality of speech differ when hearing aid compression is set at different release times at different signal to noise ratios (SNRs) for the normal and compressed rate of sentences. AIMS: To investigate the effect of amplitude-compression release time of a hearing aid on sentence recognition and quality judgment: (1) for normal rate and time-compressed sentences (2) in quiet and noisy conditions. SETTINGS AND DESIGN: A post-test repeated measures design. METHODS AND MATERIAL: We recruited fifteen adult participants with bilateral sensorineural hearing loss in each group, the younger (35-45 years), and the older ones (60-70 years). A gap detection test assessed temporal processing ability. We used three compression settings, fast-acting, slow-acting, and linear. Sentence recognition and quality and envelope difference index in normal and altered rates were assessed in quiet and in noise at these three compression settings. STATISTICAL ANALYSIS USED: A repeated measure ANOVA. RESULTS: We found a significant improvement in recognition of sentences at a normal rate in slow compression release time, compared to fast and linear gain settings at each SNR. Similar results were observed for sentences compressed at the rate of 35% in quiet and +10 dB SNR. Further, the participants preferred the quality of speech in quiet with the hearing aid set to slow compared to fast compression release time. The benefit from the slow compression release time was higher than either linear or fast compression release time on sentence recognition. Further, we saw that there was a negative impact on sentence recognition at 3 dB SNR (normal-rate) and in quiet (35% compression rate) in older adults. CONCLUSIONS: The slow compression release time in a hearing aid is superior to the fast one in noisy conditions and also with higher subjective ratings of speech quality in quiet.
