For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Screening audiometry presents tones across the speech spectrum (500 to 4,000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children).

Generally, people with normal hearing can hear all of the ranges shown on The pictures and letters in an audiogram represent the normal hearing range at different volume and pitch levels. This is used to diagnose level of hearing loss. RESULTS: Although all participants presented normal audiometry in frequencies to a range of clinical tests as having Obscure Auditory Dysfunction (OAD).
