Thus a diagnosis of functional hearing loss is based on a consideration of audiometric, otological, and other medical findings. Functional hearing loss is usually superimposed upon an organic auditory deficit, in which case it is referred to as a functional overlay. Functional hearing loss without an organic component appears to occur rarely.
One of the most commonly accepted indications of functional hearing loss is puretone threshold variability greater than ±5 db. in the absence of a known organic condition to account for such variability.3-5 There are, however, a number
