What is a normal pure tone average?

Pure-tone average. Pure-tone average (PTA) is the average of hearing sensitivity at 500, 1000, and 2000. This average should approximate the speech reception threshold (SRT), within 5 dB, and the speech detection threshold (SDT), within 6–8 dB.

How do I read my audiogram results?

It is, simply put, a graph that shows the softest sounds you can hear at different frequencies and pitches. Below you can see a blank audiogram. The numbers on the top ranking from 125 to 8000, are indicators for sounds frequencies. The higher that number, the higher is the pitch of the sound.

Is 25 dB normal hearing?

Normal –10 to 15
Slight 16 to 25
Mild 26 to 40
Moderate 41 to 55

What is normal hearing range in dB?

Normal hearing range is from 0 dBHL (Decibel Hearing Level), which is the audiometric zero, to 20 dBHL. Any threshold, at any frequency, that is over 20 dBHL is identified as hearing loss. Though a ‘normal’ audible range for loudness is 0 – 180dB, anything over 85dB is considered damaging for our hearing.

What are the 5 levels of hearing loss?

There are 5 different levels of hearing loss: mild, moderate, moderately-severe, severe and profound.
