Understanding How Hearing Loss is Measured and Graphed

Understanding How Hearing Loss is Measured and Graphed

When a person is experiencing hearing loss, it can be difficult to know what steps to take to address the problem. Making matters worse is the fact that hearing loss often creeps in over time, growing more pronounced in very small increments. Once an individual begins to notice the negative effects of hearing loss, it is time to take action. The following information is offered to help explain the process of getting your hearing tested and finding solutions.

What is an Audiogram?

An audiogram is the results of a hearing test, graphed out in a way that allows both the patient and the practitioner to have a visual representation of the degree of hearing loss. An audiogram is extremely helpful in charting how far a person's hearing has deteriorated. Having that information in hand can help determine how to best address the issue. In addition, many people choose to have hearing evaluations performed every few years, and the resulting audiograms can show the rate at which hearing loss is taking place. 

How is an Audiogram Read?

Once the patient has completed one or more hearing evaluations, a customized audiogram will be produced. At that time, the hearing professional will meet with the patient to discuss the results of the screening and to go over the audiogram. When looking at the graph, the vertical axis on the left side represents the decibels used during the testing process. The decibel levels are the most quiet at the top of the scale and grow louder as they descend. The bottom, or horizontal axis of the audiogram represents the frequency of the sounds used during the hearing tests. The lower pitch frequencies begin to the left and increase to the right. The actual results of the hearing screening are shown in lines that flow across the graph — red represents the results from the right ear and blue represents the results from the left ear. It is not uncommon for the results from each ear to vary.

The top of an audiogram graph shows the range of results that indicate normal hearing. When a patient's red and blue lines (red results coming from the right ear, blue from the left) begin to fall below that level, hearing loss is indicated.

How Does the Hearing Professional Evaluate the Results?

The graph is marked with the different ranges of hearing loss. At the top of the graph is the range of results that indicate normal hearing. When the patient's red and blue lines begin to fall below that level, hearing loss is indicated. The lower the lines fall, the more advanced the hearing loss may be. Having this information clearly charted on an audiogram can help the hearing professional determine which type of hearing device is best suited for that patient's specific hearing issues.

What Happens Next?

Once the patient and practitioner review the audiogram, a customized course of action will be determined. For many patients, being fitted with a hearing aid is the next step.
