In Depth Look At An Audiogram
The pitch is charted on the x-axis by frequencies, measured in hertz (Hz), from low to high, and the volume is charted on the y-axis, measured in decibels Hearing Level (dB HL). At the top left of the audiogram are the lower pitch sounds and at the top right are higher pitch sounds. For someone who has high-frequency hearing loss, for example, you would see a dip on their chart to the right side of the audiogram.
