The length of time varies. An initial screening may take about 5 to 10 minutes. Detailed audiometry may take about 1 hour.
You wear headphones or insert earphones. Your audiologist uses a machine called an audiometer, which delivers sounds at different frequencies (pitches) and loudness. You raise a hand, press a button or say [yes" when you hear sounds. Your audiologist records your responses on an audiogram.

Severe-to-Profound Hearing Loss 80-90 dB
As per ASHA guidelines, a pass is indicated if responses are obtained in both ears to pure-tone stimuli at 25-dB HL at 1000, 2000, and 4000 Hz. A fail is indicated if there is no response at 25-dB HL at any screening test frequency in either ear.聽力測試

The audiogram classifies your hearing within categories of normal (-10 - 20), mild (25 - 40), moderate (40 - 55), moderately severe (55 - 70), severe (70 - 90), and profound (90 - 110). Headphones or inserted earphones are used to measure air conduction results.助聽器
Audiologists use a special high-frequency test to help determine the pitch and intensity of the tinnitus. For many people, tinnitus has a consistent sound, and matching this sound to a frequency or frequencies during a hearing test helps doctors better understand how tinnitus is affecting you.
Most often, hearing loss can't be reversed. But audiologists - healthcare providers who specialize in diagnosing and treating hearing loss - can help. They can recommend treatments like hearing aids or cochlear implants that reduce hearing loss.
