The hearing threshold in women had deteriorated throughout the entire frequency range and most were at 4 and 8 kHz. Speech discrimination scores were unexpectedly high. “X” is used for the left ear and “O” represents scores for the right ear. The scores are compared to results obtained from persons with normal hearing (i.e. the line at 0dB). Bone Conduction. Sometimes the audiogram will also show bracket symbols “[” and “]”.

A person having their hearing tested responds by pushing a button when they hear a sound. The quietest level of sound heard at each pitch is then plotted on the audiogram using a red circle for right ear and a blue cross for left ear. The position of the symbols is compared to an agreed normal hearing level of 25dB across all pitches of sound.

Most people who get tinnitus soon have a audiogram done.
