Kawamura's Method (Malingering Test) by Self-Recording Audiometer

By means of self-recording audiometer combined with taperecorder, the Kawamura's malingering test (1959) was performed.At first, bilateral self-recording audiometry was carried out and the tones from audiometer which subject responded in the worse ear was recorded in tape. And when the better ear was examined, the recorded tones in the tape were submitted to the worse ear simultaneously. In these examinations, continuous tones of 500-4, 000 Hz were used.When the difference between two audiograms of the better ear was within 10 dB, malingering can be excluded.This method was comparatively objective and simple as well as practical.
