Audiograms - Why they’re Important

The audiogram is a chart that shows the results of a hearing test. This chart shows how well you hear sounds in terms of frequency — high-pitched sounds versus low-pitched sounds — and intensity, or loudness.

The results will also illustrate the hearing in each ear and tells the audiologist the softest sound you can hear at each specific frequency.This type of information is helpful for employees working in loud environments such as railway, aviation, or construction.

Frequency

Frequency or pitch is measured in Hertz (Hz). Frequencies range from low pitch to high pitch and read from left to right on the audiogram. Each vertical line represents a different frequency, such as 250, 500, 1000, 2000, 4000 and 8000 Hz.

Intensity

The intensity is measured in decibels (dB). The intensity relates to how loud or soft a sound is. Each horizontal line represents a different intensity level. The softest sounds are at the top of the chart and the loudest sounds at the bottom. Each mark on your audiogram shows the softest sounds you can hear. The softest intensity tested is typically 0 dB and the loudest is 120 dB.

Right Ear vs Left Ear

For the part of the hearing test when you used headphones, results for your right ear appear on the audiogram as either a circle or triangle. The left ear is graphed with an X or a square. These responses represent the air conduction results of either the right or left ear.
