Web6 feb. 2024 · Hearing test results can be used to determine a person’s hearing status. A hearing test can detect the softest sound a person can hear in different pitch settings. As a result, hearing tests can indicate whether a person has a low or high level of hearing. Normal hearing ranges from -10 to 20 decibels (dB). WebThey indicate the volume or loudness of the sounds required for the subject to hear. The higher the number, the louder the sound. Being able to hear sound from a smaller number represents a better hearing result. Understanding the Audiogram Symbols There are international and national standards that specify what an audiogram should look like.

Typically, the measurement is characterized by the stimulus onset (baseline), the response of the cochlea to the stimulus (summating potential - SP), and response to the synchronous firing of nerve fibers (action potential -AP). The AP is also known as Wave I.
