ABSTRACT 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.
RESUMO Objetivo Verificar as habilidades auditivas de ordenação temporal, resolução temporal e localização sonora, antes e após a adaptação do aparelho de amplificação sonora individual (AASI) em indivíduos com perda auditiva unilateral (PAUn). Método Foram avaliados 22 indivíduos, com idades de 18 a 60 anos, com diagnóstico de PAUn sensorioneural ou mista, de graus leve a severo.
