Audiograms
Audiograms determining your Hearing:
An audiogram shows your hearing loss results of a hearing test. It normally includes a chart and table for each ear showing how well you're able to hear sounds at various frequencies. It may also record some results of how your hearing system works. Most audiograms include:
o Your ability to recognize words.
o Your ability to understand words in context.
o Your ability to hear in noisy situations.
o The flexibility and response of your eardrum.
o Your auditory brainstem response.
o Your ability to recognize words.
o Your ability to understand words in context.
o Your ability to hear in noisy situations.
o The flexibility and response of your eardrum.
o Your auditory brainstem response.
How to Read and Audiogram:
Horizontal: measures the frequencies—number of vibrations—per second. Frequency is the pitch of sound and this is measured in hertz
Vertical: measures the intensity, which is the pressure of sound—also called loudness. Intensity is measured in decibels
Symbols used:
X (blue)— left ear
O (red)— right ear
A —aided
< — right ear bone conduction
> — left ear bone conduction
The audiogram on the left is a generic audiogram of sounds we should hear. There is a speech banana (light purple background) in the middle of the audiogram that shows the different sounds in our speech ranging from low to high frequencies. From left to right, it starts as primarily vowels, to mixed vowels and consonants, to primarily consonants. Throughout the chart demonstrates images of sounds we hear ranging from low to high pressure of sounds.

Different Types of Audiograms:
These examples of hearing losses are based on the left ear. Remember all audiograms are different, these are just generic examples. Typically, audiograms follow the same line pattern shown in these examples.
