Electric response audiometry and compensational noise-induced hearing loss.
With the current epidemic of compensation claims for occupational noise-induced hearing loss, the number of claimants in whom hearing test results do not reflect the true hearing status still inexorably increase. The incidence of a such cases with feigned hearing loss is reported at between 20 and 25 per cent of all patients being tested. Searching for any reliable indicators useful in uantifying a valid hearing thresholds the authors present their own experience with the electric response audiometry (ERA) by the use of the Amplaid MK 10 system a series of 56 malingerers. A suggested test protocol including the click-evoked auditory brainstem responses (ABR) and the 40 Hz logon-evoked middle latency responses (MLR) is discussed as a promising method for determining a frequency-specific threshold.
