Hearing test for Psychogenic Hearing loss

Abstract

The threshold value for the psychogenically deaf patient is not correct, but also not random. It is assumed that the patient will usually take the loudness of the test tone, for example, comfort level, as his reference.
So, in the most cases, it is assumed that the audiogram will take the shape of an equal loudness contour, espesially of 40- to 60-dB gradual sloping form, resembling a saucer.
In the Bekesy audiogram, most patients with psychogenic deafness showed a unique record, of the continuous tracing showing better hearing than the pulsed tracing (Jerger Type V). This is proof that it is a recording of the loudness, and not of the threshold.
