Adults with acquired hearing loss: identification and referral patterns of community health workers.

Community health workers in one health region of New South Wales were surveyed about their criteria and referral patterns to identify and assist adults with acquired hearing losses. Reported or observed communication problems were the most commonly used criteria for identifying hearing loss, suggesting that a failure model was being utilised. Given that the literature has previously demonstrated reluctance on the part of individuals with acquired hearing loss to report their hearing difficulties, the implications of these results are discussed. Clients suspected of having acquired hearing losses were usually referred to their doctors for further investigation and treatment. Other hearing help services were not systematically utilised. Alternative strategies for identifying and managing acquired hearing loss at the community level are needed.

Frequency-specific auditory brainstem responses relationship to behavioural thresholds in cochlear-impaired adults.

Auditory brainstem response (ABR) thresholds to ipsilaterally masked tone pip stimuli were obtained from three groups of hearing-impaired subjects. Using high-pass (for 500-Hz tone pips) and notched noise (for 1-, 2- and 4-kHz tone pips), ABR thresholds in subjects with low-frequency, high-frequency or flat cochlear hearing losses were compared to conventional pure-tone audiometric thresholds. A strong positive relationship was found between ABR and behavioural threshold elevation. Absolute ABR thresholds at 500 Hz were significantly higher than those at other frequencies. The results of this study indicate that frequency-specific ABR testing can provide an approximation of both degree and configuration of cochlear hearing losses in adults. Further refinements of testing and judging procedures are needed however to reduce the variation evident in our results and thus achieve the accuracy required for most clinical applications.
