Recently, its value as a screening test has been questioned. [6] The Rinne test is not reliable in distinguishing sensorineural and conductive loss cases of severe unilateral or total sensorineural loss. In such cases, bone conduction to the contralateral normal ear will be better than air conduction, resulting in a false negative.
Weber test, in which a tuning fork is touched to the midline of the forehead, localizes to the normal ear in people with unilateral sensorineural hearing loss. Rinne test, which tests air conduction vs. bone conduction is positive, because both bone and air conduction are reduced equally. less common Bing and Schwabach variants of the Rinne test.
For basic screening, a conductive hearing loss can be identified using the Rinne test with a 256 Hz tuning fork. The Rinne test, in which a patient is asked to say whether a vibrating tuning fork is heard more loudly adjacent to the ear canal (air conduction) or touching the bone behind the ear (bone conduction), is negative indicating that ...
In the Weber test a vibrating tuning fork (Typically 256 Hz [7] or 512 Hz [8] used for Weber vibration test; 512 Hz used for Rinne hearing test) is placed in the middle of the forehead, above the upper lip under the nose over the teeth, or on top of the head equidistant from the patient's ears on top of thin skin in contact with the bone. The ...

Heinrich Adolf Rinne (1819-1868) Heinrich Adolf Rinne (January 24, 1819 – July 26, 1868) was a German otologist born in Vlotho an der Weser. He received his doctorate from the University of Göttingen and practiced medicine in the city of Göttingen. Later he was a physician in Sandstadt near Stade (1857) and Hildesheim (1860).
In the most basic sense, there are four possible outcomes for a COVID-19 test, whether it’s molecular PCR or rapid antigen: true positive, true negative, false positive, and false negative ...
The Weber test also uses a tuning fork to differentiate between conductive versus sensorineural hearing loss. In this test, the tuning fork is placed at the top of the skull, and the sound of the tuning fork reaches both inner ears by travelling through bone. In a healthy patient, the sound would appear equally loud in both ears.
