How To Read An Audiogram Australia. An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume). By testing your hearing at different frequencies, your audiologist can ascertain which sounds are heard and which sounds are not.
An audiogram can be read from left to right for frequency and from up to down for the intensity in decibels. The higher up the chart the better the hearing, with normal being 0db to 20db. Tone frequency and pitch are read along the horizontal axis.
The vertical lines represent the test frequencies, arranged from low pitched on the left to high pitched on the right.
Horizontal lines represent the loudness, from very soft at the top to very loud at the bottom. Along the horizontal part of the graph you can see numbers relating to the different pitch or frequency of the sounds you will hear. Tone frequency and pitch are read along the horizontal axis. It indicates how much hearing varies from normal and, if there is a hearing loss, where the problem might be located in the hearing pathway.
