How are test results interpreted?

It's easy! Sound intensity (measured as SPL [dB]) is referred to as the "hearing threshold" for the tone. The purpose of one's hearing test is to find hearing thresholds for all of the test tones, and then compare the results against the "ideal" hearing thresholds which are marked as gray dots on the audiogram.

An upward deviation, referred to as "threshold shift", of more than 10 dB from an "ideal" threshold indicates a hearing loss. The severity of a hearing loss can be determined based on the provided table. Any concerns with the hearing test results should be brought to the attention of an audiologist or acoustician. They will be able to do more in-depth interpretation of the results and help determine the probable cause of your hearing loss.
