A child is considered to have hearing ability within normal limits if their responses are between 0 to 15 dB across the frequency range. 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.

Tinnitus with a normal audiogram: physiological evidence for hidden hearing loss and computational model. Schaette R, McAlpine D J Neurosci 2011 Sep 21;31(38):13452-7. doi: 10.1523/JNEUROSCI.2156-11.2011. The corresponding results are plotted on the audiogram with a Red ‘O’ representing the Right ear and a Blue ‘X’ denoting the Left ear. Fig 3: Following the Air Conduction testing, a Bone Conduction test is carried out using an oscillator to present the stimulus to the Mastoid bone (the bony protrusion behind the ear). What Is Normal Hearing On The Audiogram? Looking at the audiogram, normal hearing is represented at 25 dB and above from left to right.

In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to 15 dB at 250 Hz and 20 dB at 500 Hz. 2020-03-10 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. The further down the chart the results are plotted the louder the sound had to be made.

I did this treatment but got no real relief. I still had the fullness in my left ear which was starting to spread to my right. The ENT looked into my ears and said I was fine and there was no fluid. He administered a basic audiogram to calm my fears. The audiogram came back saying my hearing was normal.
