Design: Music quality was assessed using a rating scale for three types of music: orchestral classical music, jazz instrumental, and a female vocalist. The music stimuli were subjected to a wide range of simulated hearing aid processing conditions including, (1) noise and nonlinear processing, (2) linear filtering, and (3) combinations of noise, nonlinear, and linear filtering. Study sample: Quality ratings were measured in a group of 19 listeners with normal hearing and a group of 15 listeners with sensorineural hearing impairment. Results: Quality ratings in both groups were generally comparable, were reliable across test sessions, were impacted more by noise and nonlinear signal processing than by linear filtering, and were significantly affected by the genre of music. Conclusions: The average quality ratings for music were reasonably well predicted by the hearing aid speech quality index (HASQI), but additional work is needed to optimize the index to the wide range of music genres and processing conditions included in this study. Sumario Objetivo: El propóósito de este estudio fue determinar el impacto relativo de diferentes formas de procesamiento de seññal de los auxiliares auditivos en cuanto a la calificacióón cualitativa de la múúsica. Diseñño: la calidad de la múúsica se evaluóó utilizando una escala de calificacióón para tres tipos de múúsica: cláásica orquestral, jazz instrumental y mujer vocalista. Los estíímulos musicales estuvieron sujetos a un amplio núúmero de simulaciones de procesamiento de los auxiliares auditivos, incluyendo (1) ruido y procesamiento no-linear, (2) filtracióón linear y (3) combinaciones de ruido, no-linear y filtracióón linear. Mestra: Se obtuvieron los ííndices de calidad en un grupo de 19 sujetos normoyentes y otro grupo de 15 sujetos con hipoacusia sensorineural. Resultados: Las calificaciones cualitativas en ambos grupos fueron generalmente comparables, confiables en las diferentes sesiones, fueron máás alteradas por el ruido y por el procesamiento no linear de la seññal que por la filtracióón linear y fueron afectadas significativamente por el géénero de la múúsica. Conclusiones: El ííndice de calidad del lenguaje de los auxiliares auditivos (HASQI), pronosticóó razonablemente bien el promedio de calificacióón de la calidad de la múúsica, pero todavíía es necesario continuar la investigacióón para optimizar el ííndice para que ééste pueda cubrir una gama máás amplia de gééneros y condiciones de procesamiento incluidas en este estudio. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
