An audiometry exam (or hearing test) is a subjective test to evaluate each ear’s hearing threshold separately. The test is painless, it doesn’t cause discomfort or entail any risks, and requires active patient participation.
At some point (and for no apparent reason), we have all experienced ringing in our head or ears that may sound like a buzzing or a noise that does not come from an external source. For example, we may hear it while in a quiet place or room after having been to a concert or a nightclub.
