The Judd-Persuad test: A simple office-based tuning fork test for unilateral feigned hearing loss
In the current litigious society, separating malingerers from true hearing loss patients is ever more important, especially when compensation for industrial hearing loss is claimed. We present a novel test for feigned hearing loss which is very quick and precise, and utilises equipment readily available in the Otolaryngology office. The test is based on the well established physiological phenomenon of bone conduction and exploits the fact that there is very little (0-12dB) attenuation of sound across the skull. Step 1: A 256Hz or 512Hz tuning fork is placed on the Mastoid process of the “Good Ear” (Left). Result – The patient reports hearing the sound. Step 2: The same 256Hz or 512Hz fork is placed on the Mastoid bone of the “Bad Ear” (Right). Result – The patient reports inability to hear the sound. Step 3: The test can be repeated as above as desired to confirm the results. The Judd-Persaud test is a simple, easy to perform, quick and accurate test for unilateral feigned hearing loss in the malingerer.
