The Weber test is administered by holding a vibrating tuning fork on top of the patient's head. The Weber test is a screening test for hearing performed with a tuning fork. [1] [2] It can detect unilateral (one-sided) conductive hearing loss (middle ear hearing loss) and unilateral sensorineural hearing loss (inner ear hearing loss). [3]
A Rinne test should always be accompanied by a Weber test to also detect sensorineural hearing loss and thus confirm the nature of hearing loss. The Rinne test was named after German otologist Heinrich Adolf Rinne (1819–1868); [3] [4] the Weber test was named after Ernst Heinrich Weber (1795–1878).
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.
A hearing test provides an evaluation of the sensitivity of a person's sense of hearing and is most often performed by an audiologist using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. There are other hearing tests as well, e.g., Weber test and Rinne test.
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.

This test is usually abnormal with conductive hearing loss. A type B tympanogram reveals a flat response, due to fluid in the middle ear (otitis media), or an eardrum perforation. [ 5 ] A type C tympanogram indicates negative middle ear pressure, which is commonly seen in eustachian tube dysfunction. [ 5 ]
The Kraus–Weber test (or K–W test [1]) is a fitness test devised in the 1940s by Hans Kraus and Sonja Weber of New York Presbyterian Hospital. The poor tests results of American children versus children from European countries gained attention in the 1950s from American media, prompting the United States government to establish the Presidential Fitness Test within the following decades.
