For example, it is A normal hearing audiogram will have a set range from 10 dB to 120 dB. The threshold of hearing is 0dB, but most audio tests will begin at 10 dB, the sound of In normal-hearing ears both curves are placed on the audiogram plot within the range of values that do not exceed 20 dB HL (Fig. 19.6A).
A profound hearing loss is anything greater than 80 decibels. 2020-09-02 An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies.

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. What an audiogram of conductive hearing loss looks like In this circumstance, bone conduction result is normal white air conduction result showing there is a hearing loss. An example of mild conductive hearing loss Treatment of conductive hearing loss If someone was tested on a sound and they heard it at 10 decibels (dB) then they have normal hearing ability for that sound – if they could not hear that sound until it was played at 50dB then they have a moderate hearing loss for that sound. You won’t see the groupings on the right hand side on most audiograms. The Hearing Test Hidden hearing loss refers specifically to the reduced amplitude of sound-evoked neural responses that occurs with loss of synapses that connect the inner hair cells to the auditory nerve, so the patient’s audiometric difficulties are hidden behind a normal audiogram.

Understanding an Audiogram. Normal hearing (-10 to 25 db HL) Generally, people with normal hearing can hear all of the ranges shown on the chart. Mild hearing loss (26 to 40 db HL) People with mild hearing loss usually cannot hear soft noises.
