An audiogram is a graphical display of a person’s hearing ability. The two main components are frequency and intensity.
Frequency (or pitch) is measured in Hertz (Hz), and it ranges from low-pitch to high-pitch.
Intensity is measured in decibels (dB), and shows how loud or soft a sound is. The softest intensity tested is usually 0 dB and the loudest is 120 dB.
Each mark on an individual’s audiogram represents the softest sounds they could hear at a certain frequency. Hearing loss is classified from normal to profound at a certain frequency. This classification is determined by the hearing threshold (or the softest a sound heard at a specific frequency).
