What diagnostic test is used to measure hearing?

The primary diagnostic test used to measure hearing is an audiogram, which is conducted through audiometry. This test involves various sound frequencies and intensities to determine an individual's hearing sensitivity. Additionally, pure-tone audiometry is commonly used, where patients listen to tones at different pitches and volumes to identify the faintest sounds they can hear. Other tests may include speech audiometry and tympanometry to assess different aspects of hearing function.
