WebNormal hearing thresholds are in the range of 0 – 25 dB hearing level (HL). Thresholds that are greater than 25 dB HL are said to be outside the normal range and indicate that a hearing loss is present. There are typical patterns of hearing loss, sometimes associated with the cause of the hearing loss. http://www.nationalhearingtest.org/wordpress/?p=786#:~:text=Hearing%20thresholds%20are%20defined%20as%20the%20lowest%20level,different%20frequencies%20%28or%20Hertz%2C%20Hz%29%20in%20each%20ear. tas tafe scholarships https://beyondwordswellness.com

Symptoms include tiredness, discomfort, pain, and loss of sensitivity. Listener fatigue is not a clinically recognized state, but is a term used by many professionals.

The 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 elicits a response a specified percentag…
