__ Audiogram __ Here is an example of a blank audiogram. It shows where different sounds fall related to their decibal level (loudness) and their frequency (high and low pitch.)



=__**Count-the-Dots **__= The count-the-dots audiogram is now commonly used to explain to patients, for example, why they can hear reasonably well in quiet but their severe loss of audibility for high-frequency sounds creates a difficulty understanding speech in noisy surroundings: In noise, they can't hear many of the low-frequency speech sounds—which they normally depend upon—because those cues are now covered up with (technically, masked by) noise, and they can't make up the difference with high-frequency speech cues because they can't hear them.
