What is the typical frequency range tested in audiometry?

The typical frequency range tested in audiometry spans from 20 Hz to 20,000 Hz (20 kHz). This range encompasses the full spectrum of human hearing capabilities, with 20 Hz representing the lower threshold of audible sound for most individuals, and 20,000 Hz representing the upper threshold. Audiometry assessments aim to identify hearing thresholds across this broad frequency range to determine whether an individual has normal hearing or if there are any hearing deficits.

By testing frequencies within this range, audiologists can evaluate various aspects of hearing, including sensitivity, frequency discrimination, and potential high-frequency hearing loss, which are critical for understanding how an individual perceives speech and environmental sounds. The importance of this full range lies in the fact that many important speech sounds exist in the higher frequency ranges, making it essential for both speech understanding and overall auditory health.
