The Audiogram An audiogram is a diagram used by hearing professionals to show visually how well you can hear. An audiogram can show if you have hearing loss, what type of hearing loss you might have, and it can help identify an appropriate hearing solution.

How to read an audiogram Volume is measured in decibels and is marked from top to bottom on the chart. Pitch, or frequency, is measured in hertz and marked from left to right. The pictures and letters represent the sounds a hearing person can normally hear at different volume and pitch levels. Audiograms are set out with frequency in hertz (Hz) on the horizontal axis, most commonly on a logarithmic scale, and a linear dBHL scale on the vertical axis. For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing.

Unilateral sensorineural hearing loss: lateralize to contralateral ear. Rinne: Place the tuning fork in front of the ear and over the mastoid and determine in which position it is heard louder. Normal: air conduction > bone conduction (positive Rinne). What is normal hearing on an audiogram? Looking at the above audiogram, normal hearing ability is represented in the blue shaded area above the 25-dB line that crosses the graph from left to right. If your threshold symbols fall in the blue-shaded area, your hearing ability is considered within normal limits.

*Note: Notice how the bone conduction stays around normal hearing range as compared to the air conduction. The inner ear is completely fine as indicated by the bone conduction on the audiogram, while the air conduction is having difficulties getting through to reach the inner ear. This indicates that there is a conductive loss.

An adult is classified as having normal hearing ability if their responses indicate they heard noises between 0 and 25 dB across the frequency range. A child is considered to have hearing ability within normal limits if their responses are between 0 to 15 dB across the frequency range.

It is done to prevent non-test ear from detecting the sound presented to the test ear by crossover. It is usually done when: ABG > 10db. The difference between the AC thresholds of the right and left ear > 40db. Adult Hearing Loss Level (WHO): <25 dB: normal (no difficulty with faint speech) 26–40 dB: mild (difficulty with faint speech)
