Abstract

The hearing status of 109 Indigenous prisoners was investigated at five prison locations in Victoria, using audiological methods and face-to-face interview. The study found predominantly mild, sensorineural hearing loss. The rate of conductive hearing impairment was consistent with an age-matched general adult population (UK). All eardrums were intact, and 89% of middle-ears were normally air filled. Results showed 12% of prisoners had a hearing loss (average. 0.5, 1, 2, & 4 kHz ≥25 dB) in at least one ear, compared with 5% in an age-matched Australian adult population. More than a third (36%) had high-frequency, sensorineural hearing impairment (4 or 6 kHz ≥25 dB), in one or both ears. Over half of the inmates (58%) reported hearing problems sometimes, and 4% reported a lot of hearing trouble. The majority of prisoners (92%) reported exposures to loud noise, and tinnitus was reported by 72% of prisoners. For hearing-impaired individuals within the correctional system, the reduced ability to communicate with ease may impact detrimentally on daily interactions, and may impede progress through rehabilitation programs.

Sumario

Se investigó la condición auditiva de 109 prisioneros indígenas en cinco prisiones de Victoria, usando métodos audiológicos y entrevistas directas. El estudio encontró predominantemente, pérdidas auditivas sensori-neurales superficiales. Comparada por edades, la tasa de impedimentos conductivos fue consistente con la de la población general adulta (UK). Todas las membranas timpánicas estuvieron intactas y 89% de los oídos medios estaban normalmente ventilados. Los resultados mostraron que el 12% de los prisioneros tenían hipoacusia (25 dB para el promedio de 0.5, 1, 2 y 4 kHz) por lo menos en un oído, comparado por edades, con el 5% de la población adulta australiana. Más de un tercio (36%) tenían problemas auditivos sensorineurales en las frecuencias agudas (de 25 dB, en 4 o 6 kHz) en uno o en ambos oídos. Más de la mitad de los internos (58%) reportaron problemas auditivos esporádicos y el 4% reportaron muchos problemas auditivos. La mayoría de los prisioneros (92%) reportaron exposición a ruidos intensos y el acúfeno fue reportado por el 72% de los prisioneros. Para los individuos con impedimentos auditivos en el sistema correccional, su reducida habilidad para comunicarse fácilmente, puede impactarlos en detrimento de sus interacciones cotidianas e impedir los progresos en los programas de rehabilitación.
