Normal hertz hearing
WebThe mean sensorineural hearing loss at 4,6 and 8 kHz was 28.2 dB on initial examination and 14.6 dB by Day 30. All 11 patients had normal hearing in the contra-lateral ear (mean 13.5 dB). In this group of patients with a tympanic membrane perforation from minor trauma the conductive hearing loss was accompanied by a significant (P = 0.001) but … WebThe absolute threshold of hearing (ATH) is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism. The absolute threshold is not a discrete point, and is therefore classed as the point at which a sound …
