Your Audiology Tutorial: Demonstration

Here is a quick tutorial that utilizes a clip from The Flintstones to demonstrate how folks with different degrees of hearing loss perceive speech. You'll see an audiogram on the right side of the screen, with a curve that will dip lower with each degradation of hearing, from "normal" to "severe". As you watch, keep in mind that the audiogram measures frequency (pitch) on the horizontal axis and intensity (loudness) on the vertical one. Going left to right, pitch is low to high. Going up to down, loudness is very soft to very loud. With each example, the patient's hearing gets worse, requiring sounds to be presented louder for them to respond during a hearing test.
