The extent of hearing impairment amongst Australian Indigenous prisoners in Victoria, and implications for the correctional system.

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 >or=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 >or=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.
