An audiogram can diagnose your hearing loss and indicate what type of hearing loss you have. It can distinguish your hearing in each ear and whether you have hearing loss on one or both sides.
Included in this document are recommendations for symbols that can be used to represent ipsilateral or contralateral acoustic reflex thresholds (ART) on the audio-ram. These symbols are shown in Tables 1 and 2, and examples are given in Figures 2, 3, and 6. Implicit in plotting ARTs directly on an audiogram is the assumption that the eliciting ...
This article discusses what an audiogram shows, what the symbols mean, what doctors consider a normal range, and what a person might do next after receiving their audiogram.
Audiograms use different symbols (as shown in the key below) to differentiate between the ears and to differentiate between air and bone conduction. X-axis: frequency in Hertz (pitch) Y-axis: hearing levels in decibels (loudness) Audiogram key. Air conduction. O = Right ear unmasked. = Right ear masked. X = Left ear unmasked. = Left ear masked.
Let’s explore the symbols you’ll likely see on the audiogram after your hearing evaluation. X: This represents your LEFT ear during the pure-tone air conduction test. O: This represents your RIGHT ear during the pure-tone air conduction test.
What do the symbols on an audiogram mean? There are several different symbols used to indicate thresholds on an audiogram, depending on the specific testing conditions. Air conduction. Testing with headphones is called air conduction testing because the sound must travel through the empty space of the ear canal to reach the inner ear.
When color is available, red indicates sounds detected by the right ear, and blue indicates sounds detected by the left ear; the <> and [] symbols that indicate left and right ear thresholds were chosen to vaguely resemble a patient's ears facing the interpreter of the audiogram.
Audiogram symbols are used to represent the different frequencies and levels of hearing loss on an audiogram. They can be combined to create a visual representation of one’s hearing abilities, with the placement of the symbols indicating the frequency and degree of hearing loss.
The audiogram shows the type, degree, and configuration of hearing loss. When you hear a sound during a hearing test, you raise your hand or push a button. The audiologist will make a note of how loud the sound was at each frequency. At the end of testing, the audiogram will show what you heard.
Other symbols seen on the audiogram may show responses for the bone conduction testing. The right ear is graphed with < or [, and the left ear with > or ]. These responses can help determine whether a hearing loss is sensorineural or conductive .
