RESUMO
PURPOSE: To assess the hearing abilities of temporal ordering, temporal resolution and sound localization before and after the fitting of a hearing aid (HA) in individuals with unilateral hearing loss (UHL). METHODS: There were evaluated 22 subjects, aged 18 to 60 years, diagnosed with sensorineural or mixed UHL, from mild to severe degrees. The study was divided into two stages: the pre and post-adaptation of HA. In both phases, subjects performed an interview, application of Questionnaire for Disabilities Associated with Impaired Auditory Localization, auditory processing screening protocol (APSP) and Random Gap Detection Test (RGDT). RESULTS: This study found no statistically significant difference in sound localization and memory evaluations for verbal sounds in sequence, in RGDT and Questionnaire for Disabilities Associated with Impaired Auditory Localization. CONCLUSION: With the effective use of hearing aids, individuals with UHL showed improvement in the auditory abilities of sound localization, ordering and temporal resolution.

ABSTRACT INTRODUCTION: Unilateral hearing loss is characterized by a decrease of hearing in one ear only. In the presence of ambient noise, individuals with unilateral hearing loss are faced with greater difficulties understanding speech than normal listeners. OBJECTIVE: To evaluate the speech perception of individuals with unilateral hearing loss in speech perception with and without competitive noise, before and after the hearing aid fitting process. METHODS: The study included 30 adults of both genders diagnosed with moderate or severe sensorineural unilateral hearing loss using the Hearing In Noise Test - Hearing In Noise Test-Brazil, in the following scenarios: silence, frontal noise, noise to the right, and noise to the left, before and after the hearing aid fitting process. RESULTS: The study participants had a mean age of 41.9 years and most of them presented right unilateral hearing loss. In all cases evaluated with Hearing In Noise Test, a better performance in speech perception was observed with the use of hearing aids. CONCLUSION: Using the Hearing In Noise Test-Brazil test evaluation, individuals with unilateral hearing loss demonstrated better performance in speech perception when using hearing aids, both in silence and in situations with a competing noise, with use of hearing aids.
Resumo Introdução: A perda auditiva unilateral (PAUn) é caracterizada pela diminuição da audição em apenas uma orelha. Em presença de ruído ambiental, indivíduos com PAUn encontram maiores dificuldades que os ouvintes normais para compreender a fala. Objetivo: Avaliar o desempenho de indivíduos com perda auditiva unilateral, na percepção da fala sem e com ruído competidor, antes a após adaptação do AASI. Método: Estudo com 30 adultos, e de ambos os sexos, com diagnóstico de perda auditiva unilateral sensorioneural, de graus moderado e severo, utilizando o Hearing In Noise Test - HINT - Brasil, nas seguintes situações: silêncio, ruído à frente, ruído a direita e ruído a esquerda. Antes e após adaptação do AASI. Resultados: Os participantes da pesquisa apresentavam média de idade de 41,9 anos e PAUn predominante à direita. Em todas as situações propostas pelo HINT foi constatado melhor desempenho na percepção da fala com o uso do AASI. Conclusão: No teste HINT - Brasil, indivíduos com PAUn demonstraram melhor desempenho napercepção da fala, em tanto no silêncio quanto nas situações com ruído competidor, com usodo AASI.
