What is considered normal hearing thresholds in dB HL?

Normal hearing thresholds in decibels hearing level (dB HL) are defined within the range of -10 dB HL to 25 dB HL. This range indicates that individuals can hear sounds at these levels without any significant hearing impairment. When hearing thresholds fall within this range, it typically signifies that the auditory system is functioning properly, allowing for clear perception of environmental sounds, speech, and other auditory stimuli.

The lower limit of -10 dB HL accounts for individual variations and the presence of some levels of sound that can still be perceived clearly by a majority of the population. The upper limit of 25 dB HL ensures that individuals at the higher end can still function well in daily auditory tasks without difficulty. This information is vital in diagnosing hearing loss and determining the appropriate interventions or accommodations needed for individuals experiencing auditory challenges.
