RESUMO

INTRODUCTION: Training is an integral part of learning any skill. The vocal training helps singers attain proficiency as they are the most demanding vocal group of all professional voice users. Hence, it is necessary to evaluate the influence of training on the singer's voice. The current study objective was to investigate the influence of vocal training on voice measures (acoustic and aerodynamic) between male Carnatic singers with lower (6 months-5 years) and higher (6-10 years) training using novel task "mkaram" along with lyrical task. METHODS: Group 1 consisted of 30 trained male Carnatic singers with lower vocal training, and group 2, thirty trained male singers with higher training in the age of 18-45 years. The acoustic (frequency-related parameter, cepstral, spectral, perturbation, and noise) and aerodynamic measures (maximum phonation time and s/z ratio) of voice were obtained. The test-retest reliability was conducted on a sample of 10% of the population from each group, with a 2-week interval between the tests. Cross-sectional study design was applied. RESULTS: The statistical analysis revealed significantly decreased frequency-related parameters (semitones) such as the mean fundamental frequency, lowest fundamental frequency, highest fundamental frequency at the low register and the highest fundamental frequency at the middle register in group 2 during "mkaram" task (p ≤ 0.05). Similarly, one of the spectral-related measures 1st harmonic-2nd harmonic (dB) during lyrical task and one of the noise-related measure harmonic-to-noise ratio (dB) at the middle register during "mkaram" task showed a significant decrease in group 2 compared to group 1 (p ≤ 0.05). Test-retest reliability revealed that most of the parameters had "acceptable to excellent" internal consistency (Cronbach's α >0.7 to 1). CONCLUSION: Few frequency and noise measures during "mkaram" task and a spectral measure during lyrical task showed to be sensitive in distinguishing the impact of vocal training on the voices of male Carnatic singers. The higher vocal training was found to help the singers to perform more efficiently with enhanced vocal range particularly in the low register and to some extent in the middle register. Indeed, the study highlighted the positive effects of vocal training on male Carnatic singers.

RESUMO

INTRODUCTION: Tinnitus is defined as the perception of sound mainly due to the activity within the central nervous system without any mechanical, vibratory activity within the cochlea. Administration of tinnitus related questionnaires along with the audiological test battery is recommended in routine clinical practice. Tinnitus Handicap Inventory (THI) is one of the useful and widely recognized tools for quantifying the impact of tinnitus on daily life. India, being a multilingual country with a multicultural background, there is no such inventories available in many of the local Indian languages except in Tamil and Kannada. MATERIALS & METHODS: The English THI was translated to Malayalam by a faculty who is qualified and proficient in Malayalam language. Then the translated THI was given to 40 native Malayalam speakers for content validity. The final THI-M was administered on 50 tinnitus patient. Obtained data was then subjected for statistical analysis using SPSS Statistics 17.0. RESULTS: Reliability statistics revealed an alpha score of 0.855 for the overall inventory. Across the three subscales, i.e. emotional, functional and catastrophic, a global alpha score of 0.766, 0.693 and 0.630, respectively. The alpha score remained the same even after deleting any single item. CONCLUSION: The results of the current study conclude that, THI-M has a good reliability/internal consistency as per the Cronbach's alpha score. THI-M can be considered as a reliable tool that can be used across the State by Hearing Professionals in assessment and management.
