Which test evaluates hearing acuity using a tuning fork?

The test that evaluates hearing acuity using a tuning fork is the Rinne test. This test is designed to assess how well sound is transmitted through the air compared to the bone. When conducting the Rinne test, a vibrating tuning fork is placed on the mastoid bone behind the ear (bone conduction), and then moved next to the ear canal (air conduction). The difference in the duration of sound perceived through air versus bone helps determine if hearing loss is present and whether it is conductive or sensorineural.

In contrast, while the Weber test also utilizes a tuning fork to assess hearing, it measures sound lateralization and identifies unilateral hearing loss instead of directly comparing air and bone conduction. The convergence test is unrelated to hearing and assesses the coordination of eye movements. The pupillary reflex test evaluates the response of pupils to light and does not involve hearing assessments. Hence, the Rinne test is the appropriate choice for evaluating hearing acuity with a tuning fork.
