The audiogram is a chart of hearing sensitivity with frequency (tone pitch) charted on the x-axis (horizontal axis) and intensity (loudness) on the y-axis (vertical axis) Intensity is the level of sound power measured in decibels (dB); loudness is the perceptual correlate of intensity
- A graph which plots the type and degree of a person's hearing loss It reflects the frequency (pitch) and intensity (loudness), marked in decibel units
