Click-evoked otoacoustic emissions (EOE) were recorded in 24 normals and 2 patients with sensorineural hearing loss. Frequency analysis of EOE was performed at every 100Hz bandwidth between 1 and 2KHz with the use of a dual channel variable filter. In normal subjects, low frequencies tended to have longer group latencies than high frequencies. In a case of sudden deafness, EOE became clearly detectable from lower frequencies with hearing improvement. In a case of Meniere's disease with low tone loss, EOE were detectable only at higher frequencies than 1.5KHz.
