This document discusses tuning fork tests used to evaluate hearing, including the Weber, Bing, Rinne, and Schwabach tests. The Weber test determines whether a hearing loss is sensorineural or conductive by placing a tuning fork on the head and having the patient indicate the side heard. The Bing test evaluates occlusion effect by placing a tuning fork on the mastoid and having the patient report if the sound is louder with the ear open or closed. The Rinne test compares air conduction to bone conduction to identify conductive hearing losses.
