The Bing test, was devised by German otologist Albert Bing. The test uses a low-frequency tuning fork to test for the occlusion effect

Occlusion effect

The occlusion effect occurs when an object fills the outer portion of a person's ear canal, and that person perceives "hollow" or "booming" echo-like sounds of their own voice. It is caused by bone-conducted sound vibrations reverberating off the object filling the ear canal...

. The tuning fork can be replaced by a bone-conduction vibrator in the audiometric Bing test.

The Bing test can simulate unilateral (one-sided) conductive hearing loss

Conductive hearing loss

Conductive hearing loss occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane , or middle ear ....

 results by placing a finger in one ear while performing the Weber test

Weber test

The Weber test is a quick screening test for hearing. It can detect unilateral conductive hearing loss and unilateral sensorineural hearing loss...
