Passaggio on chorists' voice range profile: preliminary study of frequency and intensity. / Nota de passagem no perfil de extensão vocal de coristas: estudo preliminar de frequência e intensidade.

PURPOSE: To analyze the passaggio in the voice range profile of choristers, by identifying the fundamental frequencies and intensities, both in the change to the high and low registers, comparing them, by voice types. METHOD: 67 choristers participated, mean age of 27.79 (± 7.50) years old, of the following voice types: soprano (n = 20), alto (n = 17), tenor (n = 15) and bass (n = 15). For data collection and analysis, the Vocalgram software (CTS Informática) was used, which recorded the emission of the vowel / Ɛ / in ascending and descending glissando, up to the lowest and highest note in the weakest and strongest intensities possible. RESULTS: The values of frequencies and respective intensities of the passaggio were identified in ascending and descending, strong and weak emissions in all voice types. There was a higher occurrence of voice break in the high voices, compared to the low ones. The average values ​​of the frequencies found corresponded to different tones from those established in the literature for all voice types. CONCLUSION: The passaggio identified in the vocal range profile of choristers, based on their frequencies and intensities were more frequent in soprano na tenor, compared to alto and bass, in changes to the low and high registers.

OBJETIVO: Analisar a nota de passagem no perfil de extensão vocal de coristas, pela identificação das frequências fundamentais e intensidades, tanto na mudança para o registro agudo quanto para o grave, comparando-as, por naipe. MÉTODO: Participaram 67 coristas, com média de idade de 27,79 (±7,50) anos, dos naipes: soprano (n=20), contralto (n=17), tenor (n=15) e baixo (n=15).

Effects of the Voiced Tongue Trill Technique in Glissandos on the Voice Range Profile of Choir Members: A Preliminary Study.

The objective of this study was to verify the immediate effect of the voiced tongue trill technique in ascending and descending glissandos on the voice range profile of choir members. A total of 25 sopranos, mezzo-sopranos, contraltos, tenors, and baritones participated in the study. They were choir members, aged 20 to 45 years, with no voice symptoms, and able to perform the voiced tongue trill technique. Their voice range profile was analyzed before and after performing the ascending and descending technique for 2 and 5 minutes. The maximum fundamental frequency values in the study groups increased after performing the ascending and descending technique for 2 minutes (P = 0.001) and 5 minutes (P = 0.003). The range in Hz increased after 2 minutes (P = 0.010) and 5 minutes (P = 0.050) of the ascending technique and after 2 minutes (P = 0.001) of the descending technique, and the minimum fundamental frequency mean value suffered interference from the type of technique (ascending/descending). The immediate effects of VTTT in glissandos on the VRP of choir members' considering the two factors: condition and time, in ascending and descending glissandos for 2 and 5 minutes increased the maximum frequency and the range in Hz of choristers. Regarding volume levels results, no difference was found in intensity after applying the technique.

Immediate Effect of the Finger-Kazoo Technique Associated with Glissandos in the Voice of Individuals with Parkinson's Disease.

OBJECTIVE: To verify the immediate effect of the Finger Kazoo technique associated with glissandos in the voice of individuals with Parkinson's disease. METHOD: Thirty subjects with Parkinson's Disease comprised of 15 men and 15 women with a mean age of 63.8 years (± 6.88) and mean time of diagnosis of 97.33 (± 63.53) months, all with preserved cognition. The subjects' voice range profile (VRP), speech range profile (SRP), and the maximum phonation time were assessed, before and after applying the Finger Kazoo technique associated with ascending and descending glissando. After the technique, a vocal satisfaction questionnaire was completed. RESULTS: After the applied technique there was an increase in the minimum and maximum fundamental frequency recorded respectively in the SRP and in the VRP; there was an increase in the vocal range (measured in Hertz and semitones) of the women, recorded in the VRP; in the male population, there was an increase in maximum phonation time. A higher percentage of positive references to vocal improvement was observed after the exercise. CONCLUSION: In patients with Parkinson's Disease, the Finger Kazoo with glissando technique promoted an increase in the minimum fundamental frequency of the SRP and in the vocal extensions of women, as well as increasing the maximum phonatory time of men. In addition, patients reported satisfaction with the use of the technique and its results.

Minor Structural Alterations of the Vocal Fold Cover: Vocal Quality before and after Treatment.

Introduction Minor structural alterations of the vocal fold cover are important causes of dysphonia. The variability in the type of alteration and the grade of vocal deviation affects the definition of the conduit and the results of treatment. Objective To characterize the occurrence, the selected treatments adopted and vocal quality before and after treatment in patients with minor structural alterations of the vocal folds cover. Methods This was a cross-sectional study based on the records of patients treated by an interdisciplinary team at the laryngology outpatient clinic of a public university hospital from 2010 to 2018. Data collection consisted of access to a database of information on otorhinolaryngological diagnostic hypotheses, intervention and perceptual-auditory vocal assessments before and after the treatment. Data from 102 subjects were analyzed. Association tests were applied between the perceptual-auditory vocal results and the different alterations found and between these and the adopted treatments. The results of the degrees of vocal deviation before and after treatment were also compared. Results The degree of roughness was associated with the sulcus vocalis, and in this alteration the highest occurrence was mild degree of roughness. There was an improvement in the breathiness and general grade of vocal deviation after treatment. Conclusion Cysts were the most frequent structural alteration in the population studied. There was an association between the degree of general deviation and that of roughness in sulcus vocalis cases. The breathiness and the general grade of vocal deviation improved after treatment regardless of the type of treatment and alteration.

Do Flexible Silicone Tubes Immersed in Water Combined With Vocalise Improve the Immediate Effect on Voice?

PURPOSE: This study aimed to analyze the immediate effect on a singer's voice of a flexible silicone tube immersed in water combined with ascending and descending vocalise scales compared with ascending and descending vocalise scales alone. METHOD: A pre- and post-intervention quasi-experimental study was conducted. Thirty adult singers between 18 and 45 years old with no laryngeal disorders performed the two techniques for 3 min each on different days. Acoustic measurements of frequency, jitter, shimmer, glottal-to-noise excitation ratio, noise, smoothed cepstral peak prominence (CPPS), maximum phonation time (MPT), voice range profile, and self-perceived vocal effort (Borg Category Ratio 10-BR Scale adapted for vocal effort) were assessed before and after performing the techniques. RESULTS: The results indicated an increase in singers' CPPS and MPT values and a decrease in shimmer and noise when performing with a flexible silicone tube immersed in water combined with vocalise. The singers reported a perception of decreased vocal effort after both methods. However, the diminished perceived vocal effort became more pronounced with the tube phonation technique combined with vocalise. CONCLUSIONS: Phonation in tubes combined with vocalise improved the vocal acoustic parameters (including cepstral measurements), increased MPT, and diminished perceived vocal effort. Although using vocalise alone diminished perceived vocal effort, this decrease was more pronounced in the tube phonation technique combined with vocalise.

Immediate Effect of a Resonance Tube on the Vocal Range Profile of Choristers.

OBJECTIVE: The aim of this study was to determine the immediate effect of the resonance tube technique associated with ascending and descending glissando on the vocal range profile (VRP) of amateur choristers. METHOD: The sample consisted of 40 choristers aged between 18 and 57 years (average of 26.28 ± 7.51 years) with the following voice types: soprano, contralto, tenor and bass, with no vocal symptoms. Recordings of the VRP of the choristers were made before and after performing the resonance tube technique executed in ascending and descending glissando for 3 minutes in each modality. The recordings were made in the VRP of specific software. RESULTS: The VRP of the choristers increased after application of the ascending and descending technique. Stratifying by voice types showed an increase in contralto, tenor and bass after the ascending glissando technique and in tenor and bass after the descending technique. CONCLUSION: The resonance tube technique associated with ascending and descending glissando increased the VRP in contralto, tenor and bass voice types, as well as the maximum frequency and range in hertz and semitones, in all the voice types of the choristers under study, justifying its application in the vocal warm-up of this population.
