Abstract
A computerized method for determining a test subject's (TS) hearing threshold (HT). An acoustic stimulus (AS,) is applied the test subject's (TS) ear. The stimulus intensity is increased during a ramp, with a predetermined dependency on time, such that the intensity begins below the hearing threshold and ends above it. The test subject's brain response (), which includes a transient brain response (TR)is non-invasively recorded during the ramp section. The stimulus-response cycle is repeated several times. The recorded brain responses and stored a-priori information on transient brain response to the acoustic stimulus are used to determine a combined time interval between the acoustic stimulus and the transient brain response. The test subject's hearing threshold is determined based on the predetermined dependency on time of the intensity during the ramp and the combined time interval between the acoustic stimulus and the transient brain response.
