Which hearing loss can be diagnosed using the Weber test?

The Weber test is a clinical test used to evaluate hearing loss by using a tuning fork. When the fork is struck, it produces vibrations that create sound. The test assesses where the sound is perceived relative to both ears, which helps in distinguishing between types of hearing loss.

In the case of conductive hearing loss, the sound from the tuning fork will lateralize to the affected ear. This is because conductive hearing loss typically results in a reduction of sound being transmitted through the outer or middle ear, making the affected ear more sensitive to vibrations compared to the unaffected ear. The sound is perceived louder in the ear with the conductive loss due to the dampening of external sound entering the unaffected ear.

The other types of hearing loss do not align with the Weber test's pattern as clearly. In cases of sensorineural hearing loss, sound will lateralize to the better-hearing ear because the compromised ear has difficulty processing sounds effectively. Mixed hearing loss, which has both conductive and sensorineural components, can have varied results. Central hearing loss pertains to problems in the central auditory pathways rather than an ear issue, making it less applicable for detection using the Weber test.

Thus, the Weber test is an effective way to diagnose conductive hearing loss due to the distinct way
