How To Read An Audiogram Australia. Air conduction thresholds for the right ear (that is, the softest sounds the right ear can hear at each frequency) are marked as an ‘o’ and the left as an ‘x’ on the audiogram. Red represents the right ear and blue represents the left. An audiogram resembles a graph. How to read an audiogram.

Your audiologist will advise you about the hearing thresholds for each ear at the end of the hearing test. 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. If the hearing thresholds obtained by bone conduction are the same as the air conduction thresholds, this indicates that there is nothing stopping the sound from traveling through the outer or middle ear to the cochlea. Tone frequency and pitch are read along the horizontal axis. If there is hearing loss an audiogram helps distinguish conductive loss (outer/middle ear) from sensorineural loss (cochlea/cochlear nerve). How to read an audiogram.
The audiogram is the graphical representation of the results of the air conduction and bone conduction hearing tests.
The higher up the chart the better the hearing, with normal being 0db to 20db. How to read your audiogram. Essentially, it can be best understood as a visual representation of your hearing. 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 above audiogram the left ear (crosses) show a mild hearing loss and the right ear (noughts) show a moderate to severe hearing loss. The quietest tone (0 db) is at the top of the axis.

Understanding the information shown on an audiogram is easy. Tone frequency and pitch are read along the horizontal axis. Essentially, it can be best understood as a visual representation of your hearing. On the audiogram shown here you can see the vertical lines represent the frequency (tone) measured and the horizontal lines display the volume (loudness) required. When you have a consultation with an audiologist because you are experiencing hearing loss, it is likely that you will have a hearing test to measure how well you can hear and any possible levels of hearing loss.

The quietest tone (0 db) is at the top of the axis. On the audiogram shown here you can see the vertical lines represent the frequency (tone) measured and the horizontal lines display the volume (loudness) required. In the above audiogram the left ear (crosses) show a mild hearing loss and the right ear (noughts) show a moderate to severe hearing loss. Let’s look at an example. Along the horizontal part of the graph you can see numbers relating to the different pitch or frequency of the sounds you will hear.

The audiogram shows how loud a sound has to be for the patient to hear it at a particular frequency. Then look to see if the bone conduction is in the normal range (above 20db). An audiogram can be read from left to right for frequency and from up to down for the intensity in decibels. On the audiogram shown here you can see the vertical lines represent the frequency (tone) measured and the horizontal lines display the volume (loudness) required. An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume).

Sounds at low frequencies have a lower pitch, such as a dog barking or the noise of a lawnmower. It graphs how it may (or may not) differ from the normal hearing range, by showing your hearing threshold levels at different frequencies. This is measured in hertz (hz). Along the horizontal part of the graph you can see numbers relating to the different pitch or frequency of the sounds you will hear. The closer all the symbols are to the top of the audiogram graph, the better your hearing is.

Your audiologist will advise you about the hearing thresholds for each ear at the end of the hearing test. Along the horizontal part of the graph you can see numbers relating to the different pitch or frequency of the sounds you will hear. The vertical lines represent the test frequencies, arranged from low pitched on the left to high pitched on the right. By testing your hearing at different frequencies, your audiologist can ascertain which sounds are heard and which sounds are not.
