This is an essential test for patients undergoing hearing aid assessment and fitting in order to calibrate the device appropriately. The test is used to determine the minimum loudness level of a sound that you judge to be uncomfortably loud. Loudness discomfort level is the intensity at which sound, particularly speech, causes discomfort. Hypersensitivity hearing is most commonly associated with hearing loss. Loudness discomfort is typically a problem for people who suffer from sensorineural hearing loss, whereas it is not a problem for people who suffer from conductive hearing loss.
