Audiometry testing is a useful way to gauge your hearing capabilities. It is made more effective with multiple tests over a period of time, as this allows you to see any changes in your hearing and address any problems as they arise. Still, when given a line graph with numbers and symbols on it, you may not be able to decipher their meaning without a proper explanation. That is what we offer below.
Defining the X and Y Axis’s of Your Audiometry Test
Typically, the X-axis (horizontal) of your audiometry test will be the frequency of the sound, measured in hertz (Hz). Frequency is the measure of a soundwave’s repetition in a certain time frame. Lower frequencies sound deeper and repeat less often. Higher frequencies sound higher and repeat more often.
The Y-axis (vertical) of your audiometry test represents the intensity of the sound, expressed in decibels (dB). Intensity is a measure of the soundwave’s energy and acts much like the volume buttons on a television remote. More decibels mean a louder sound, which is easier to perceive.
Defining the Plotted Line of Your Audiometry Test
Audiometry testing assesses your ability to hear a range of frequencies. As you proceed through the test, the intensity of the sound will increase until you indicate you can hear it. Each point on the line is where you indicated you could hear the frequency and the intensity of the sound at that time.
An adult with no hearing loss will identify all frequencies within 0 to 25 dB, and a child 0 to 15 dB. Results with higher intensities indicate that the individual has experienced some hearing loss, which can be addressed with hearing aids and other methods if needed.
