These tests are usually given in a soundproof room using electronic equipment. The tests are not painful or difficult to do. You are asked to signal when you hear tones and sounds that come through the earphones. Other tests will show if you can tell the difference between words that sound much alike such as fin, pin, tin, and thin . Audiogram is a graph showing the results of your hearing test.
Soft sounds are at the top of the graph and loud sounds at the bottom.
The loudness where you first hear a tone is marked and these points are connected to form a line. Normal hearing levels start between 0 and 20 decibels.
