Hearing Test Frequency

Hearing tests assess a range of frequencies, typically from low frequency of 250 Hz to 8000 Hz, covering the audible spectrum for humans.

It's recommended to have a baseline hearing test by age 50, then every 3-5 years after that unless specific concerns arise.

Hearing sensitivity varies, but most deaf people can hear frequencies from 20 Hz to 20,000 Hz when they're young. However, this range often decreases with age.
