In the Weber test, a 512 Hz tuning fork is placed on the patientâs forehead. If the sound lateralizes (is louder on one side than the other), the patient may have either an ipsilateral conductive hearing loss or a contralateral sensorineural hearing loss. Other tuning fork tests include the Bing and Schwabach tests. In the Bing test, the fork is struck and placed on the patientâs mastoid tip. The examiner alternately occludes the patientâs external meatus. If the patient has normal hearing or a sensorineural loss, he or she will notice a change in intensity with occlusion.
