Getting a hearing test done? Understanding your audiogram can be a bit of challenge if you don’t know what everything means. Here we break down the hearing test for you in simple terms that will make sense.

The Audiogram Chart

An audiogram is a test of hearing acuity. The hearing test is represented in a graph form. The graph is laid out with low to high frequencies going across the top from left to right, and low to high intensity (volume) going down the chart from top to bottom. The test will measure the quietest tone that you can hear at each pitch across a range of frequencies. As you’re tested for hearing sensitivities, the graph will get filled in with shapes; these shapes are the reactions of your left and right ear.

Right Ear vs. Left Ear

On the audiogram, your right ear will be represented by either a circle or a triangle. The left ear will be represented by an x or square.

Frequency

The frequency represents different pitches. On the graph, you will see frequency being represented across the top, starting at 250hz and increasing in increments up to 8000hz. The low pitches are represented between 250hz to about 1500hz and high pitches range from 1500 up to 8000hz.

Intensity Line

Hearing volume is not measured in percentages but decibels. Normal hearing ranges from 0 to 25dB to give you an idea. On the graph, the horizontal lines represent the different intensity levels. If you look at the 25dB line, any hearing that falls between 0 and 25dB will be normal. If there are X or O letters that fall below that line, or above 25dB, it is an indication that you have hearing loss.

Levels of Hearing Loss

Mild hearing loss can be found between the intensity lines numbered 21dB to 40dB. Moderate hearing loss falls between 41dB to 55dB. If you have moderately severe hearing loss, you will place between 56dB to 70dB on the chart. Severe hearing loss starts at 71dB and moves up 90dB. Profound hearing loss is anything 91dB and beyond.

Are you concerned about hearing loss? Do you have trouble hearing soft sounds or high and low pitches? An audiogram is just one of several tests available to your audiologist to measure hearing health. In addition to the hearing acuity test, your audiologist will take a full case history, perform an otoscopy, test eardrum motility, speech understanding, and remove wax if needed.
