The audiologist will give you instructions for each sound. Your audiologist or an assistant will play a variety of sounds, such as tones and speech, at different intervals into one ear at a time, to determine your range of hearing. It involves using an audiometer, which is a machine that plays sounds via headphones. A pure tone test measures the quietest sound you can hear at different pitches. There are a few tests involved in audiometry. This type of hearing loss is usually permanent. Sensorineural hearing loss can also occur due to damage to the nerve that carries sound information to the brain or damage to part of the brain that processes this information. The cochlea is the part of the ear that translates sound vibrations into nerve impulses to be sent to the brain. Sensorineural hearing loss occurs when hair cells in the cochlea aren’t working properly. It’s good to use hearing protection, such as foam earplugs, if you’re exposed to loud music or industrial noise on a regular basis.

Human speech generally falls in the 500-3,000 Hz range.Īn audiometry test is performed to determine how well you can hear. Humans can hear tones between 20-20,000 Hz. The unit of measure for tone is Hertz (Hz). The tone of a sound is measured in cycles per second. A loud sound such as a jet engine is between 140 and 180 dB. A healthy human ear can hear quiet sounds such as whispers. The unit of measure for sound intensity is the decibel (dB). A doctor who specializes in diagnosing and treating hearing loss called an audiologist administers the test. It tests both the intensity and the tone of sounds, balance issues, and other issues related to the function of the inner ear. One way to test for hearing loss is through the use of audiometry.Īn audiometry exam tests how well your hearing functions. According to a study in American Family Physician, at least 25 percent of people over 50 experience hearing loss, and 50 percent of people over 80 experience it.
