Bing test
The Bing test, was devised by German otologist Albert Bing (1844-1922) in 1891. The test uses a low-frequency tuning fork to test for the occlusion effect. 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 results by placing a finger in one ear while performing the Weber test
