Abstract

This study evaluated the use of multiple auditory steady-state responses (ASSRs) to estimate the growth of loudness in listeners with normal hearing. Individual intensity functions were obtained from measures of loudness growth using the contour test and from the electrophysiological amplitude measures of multiple amplitude-modulated (77–105Hz) tones (500, 1000, 2000, and 4000Hz) simultaneously presented to both ears and recorded over the scalp. Slope analyses for the behavioural and electrophysiological intensity functions were separately performed. Response amplitudes of the ASSRs and loudness sensation judgements increase as the stimulus intensity increases for the four frequencies studied. A significant relationship was obtained between loudness and the ASSRs. The results of this study suggest that the amplitude of the ASSRs may be used to estimate loudness growth at least for individuals with normal hearing.

Sumario

El estudio evaluó el uso de respuestas auditivas múltiples de estado estable (ASSR) para estimar el aumento en la apreciación subjetiva de la intensidad en sujetos con audición normal. Las funciones individuales de intensidad se obtuvieron de mediciones en el aumento de la apreciación subjetiva de la intensidad usando pruebas de contorno y partir de las medidas electrofisiológicas de amplitud de múltiples tonos (500, 1000, 2000 y 4000Hz) modulados en amplitud (77–105Hz), presentados simultáneamente en ambos oídos y registrado en el cráneo. El análisis de las pendientes para las funciones electrofisiológicas y conductuales de intensidad se realizó separadamente. Las amplitudes de respuesta de las ASSR y los juicios de sensación sobre la apreciación subjetiva de la intensidad aumentaron conforme la intensidad de los estímulos aumentó en las cuatro frecuencias estudiadas. Se obtuvo una relación significativa entre la apreciación subjetiva de la intensidad y las ASSR. Los resultados de este estudio sugieren que la amplitud de las ASSR puede ser usada para estimar el aumento en la apreciación subjetiva de la intensidad, al menos para individuos con audición normal.
