The results of hearing testing are presented on an audiogram, which is a chart that allows professionals to diagnose the severity of hearing loss. They also help you find the perfect hearing aid for your needs, which is essential to your quality of life. While the technician will explain test results during your appointment, knowing how to read an audiogram is also quite beneficial for patients. 

Frequency and Loudness

Audiograms feature a horizontal and vertical axis, over which hearing thresholds are displayed. Hearing thresholds indicate the softest sound you can hear at least half of the time. 

Thresholds measuring between 25 and 40 decibels higher than the average person indicate mild hearing loss, while 55 to 70 decibels higher than normal signals moderate to severe hearing loss. The horizontal axis measures frequency, while the vertical axis measures loudness according to decibel levels. 

Testing Conditions

In addition to frequency and loudness, thresholds for different testing conditions are also indicated in your hearing testing results. Conditions are marked by certain symbols, which provide information on how the test was conducted. Symbols appear in red when relating to the right ear, or appear in blue when relating to the left ear. 

Bone conduction testing involves holding a device behind each ear and playing sounds, which then travel through bone tissue to reach the inner ear. The results of this test are marked with "<" or "[" symbols. 

Conversely, air conduction testing entails playing sounds through headphones. These results are marked with a red "O" for the right ear or a blue "X" for the left. Thresholds relate to lines for each ear. If these lines overlap, it means that you have the same type of hearing loss in both ears.
