RESUMO

Introduction: According to data from the Brazilian Institute of Geography and Statistics, the life expectancy estimated at birth in Brazil, for both sex, increased to 71,3 years. The life expectancy increase reflects in special attention necessities to the elderly population, and it falls to the Speech-Language and Hearing Science the parcel that concerns to the communication disorders. The hearing loss, among others, is one of the disorders referred to this age group. It is known that the auditory feedback system is primordial on human vocalizing, organizing the vocal production. Objective: To assess and correlate the hearing and vocal production of elderly who have neurossensorial hearing loss with different degrees and audiometric configurations. Method: Participated in this study 40 subjects from whom 10 were male and 30 were female, whose ages varied from 60 to 93 years old, mean age of 75,95 (SD = 7,41), and who were sent from the Gerontology and Geriatrics Institute of the Federal University of São Paulo. The inclusion criteria considered the ones with symmetric neurossensorial hearing loss, descending configuration and a type A tympanogram. The subjects were submitted to an anamnesis, an auditory assessment (Pure Tone Audiometry, Word Recognition Score and Tympanometry) and vocal assessment. The audiometry were classified into degrees for low frequencies (500Hz, 1 e 2 KHz) and high frequencies (2, 3 e 4 KHz) based on Silman and Silverman (1997). The acoustic analysis of the vocal parameters was done through the CSL Program, from Kay Elemetrics Corporation, 1993/1994 version, MVDP module. Results: In the higher hearing loss degrees, an increase of the fundamental frequency. The maximum phonatory extension, in semitones, and maximum phonation time decreased in hearing losses with higher degrees, while the mean speech loudness increased. Conclusion: In an elderly individual with hearing loss, in whom it is expected an altered auditory-vocal monitoring, the higher hearing loss degree, the greater modifications observed on vocal parameters.
