What is considered the normal range of hearing in decibels (dB)?

The normal range of hearing is defined as the ability to hear sounds in the range from 0 dB to 20 dB. This range indicates the faintest sounds that a person with typical hearing can perceive. Sounds below 0 dB are typically not audible to the average person, while sounds above 20 dB are within common conversational levels and many environmental sounds. The measurement in decibels (dB) refers to the intensity of sound, and understanding this range is crucial when assessing hearing abilities or diagnosing hearing loss.

Other options represent levels of hearing that are typically considered to be beyond the normal threshold for hearing, which may reflect varying degrees of hearing sensitivity or hearing impairment.
