The primary goal of this study was to examine the relationship between listeners' loudness growth and their satisfaction with loudness when wearing wide-dynamic-range compression (WDRC) hearing aids. An absolute-magnitude-estimate procedure was used to obtain listeners' unaided and aided loudness growth functions in response to a 500 and 2000 Hz warble tone. In general, listeners' unaided loudness growth functions were steeper than the average normal-hearing listeners' functions for both frequencies, and their aided loudness growth functions were shallower than their unaided functions. Loudness growth functions tended to be undercompressed for 500 Hz but overcompressed for 2000 Hz. The Profile of Aided Loudness (PAL) questionnaire was administered to determine listeners' loudness satisfaction in everyday listening situations. Most listeners were satisfied with their perception of soft, average, and loud environmental sounds, regardless of how well or not well their WDRC aids normalized their aided loudness growth. La meta primaria de este estudio fue examinar la relación entre el crecimiento de la apreciación subjetiva de la intensidad (sonoridad) en el oyente y su satisfacción con dicha sonoridad ante el uso de auxiliares auditivos con compresión de rango dinámico amplio (WDRC). Se utilizó un procedimiento de estimación absoluta de la magnitud para obtener en los sujetos las funciones de crecimiento de la sonoridad, con amplificación y sin ella, en respuesta a tonos modulados de 500 y 2000 Hz. En general, las funciones de crecimiento en la sonoridad sin amplificación mostraron una pendiente más pronunciada que dichas funciones para normo-oyentes, en ambas frecuencias, y en las mismas funciones con amplificación, las pendientes fueron menos profundas, que en aquellas sin amplificación. Las funciones de sonoridad tendieron a estar sub-comprimidas en 500 Hz pero sobre-comprimidas en 2000Hz. Se administró el cuestionario del Perfil de Sonoridad con Amplificación (PAL) para determinar la satisfacción del oyente a este incremento subjetivo de la intensidad en situaciones auditivas cotidianas. La mayor parte de los sujetos estuvieron satisfechos con su percepción de sonidos ambientales suaves, promedio y fuertes, independientemente de cuán bien sus auxiliares auditivos con WDRC normalizaran este crecimiento en la sonoridad.
