Hearing Loss Levels. Normal = less than 25 dB HL. Mild = 25-40 dB HL. Moderate = 41-65 dB HL. Severe = 66-90 dB HL. Profound = more than 90 dB HL. What Happens During The Test? The audiometry tests are conducted in an isolated environment. Earphones will be plugged on your head. The audiologists will ask you to sit still and not to talk.

Mild hearing loss: 25 to 40 dB higher than normal Moderate hearing loss: 40 to 55 dB higher than normal Moderate-to-severe hearing loss: 55 to 70 dB higher than normal Severe hearing loss: 70 to 90 dB higher than normal Profound loss: 90 dB or more

Given ‘The Stenger Principle’, you perform the test by presenting tones to both ears at the same time. Set the intensity level to 10 or 20 dB above the threshold in the good ear and 10 or 20 dB below the threshold in the poor ear. Keep the intensity level in the good ear fixed while increasing the intensity in the poor ear in 5-dB steps.

Test frequencies in audiometry are derived from the musical scale, and are generally octave intervals. An octave is a tone with a frequency that is exactly twice that of a reference tone. Therefore, the basic audiometric test frequencies are 500, 1000, 2000, 4000, and 8000 Hz.

practical purposes, normal hearing ranges from 0 to 25 dB HL. The scale extends to 95,100, or 105 dB HL depending on the output limit of the audiometer. T K Group audiometers have a maximum output of 95 dBHL. When no response is made after numerous 95 dB HL signal presentations, a ³no response´ (NR) level is recorded.

The term dB HL describes your hearing loss in decibels. The table below shows a common way to classify hearing loss. If you can only hear sounds when they are at 30 dB, you have a mild hearing loss. You have a moderate hearing loss if sounds are closer to 50 dB before you hear them. To find out how loud common sounds are, visit the noise page.
