Have you noticed changes in your hearing and want to understand the results of your hearing test? These tests are done with the purpose of providing a chart which is referred to as an audiogram, and which offers an in-depth representation of a person’s hearing across various frequencies. This chart will indicate how well an individual will be able to hear certain types of sound that they may encounter on a regular basis. Let’s take a deeper look into the audiogram and the significance of its readings.
The Audiogram Explained
An audiogram is a chart that offers a visual representation of your ability to hear across the spectrum of frequencies. It is plotted as a line graph with two axes, the horizontal X axis and the vertical Y axis.
Horizontal axis: This shows the frequency of sounds, typically ranging from 250 hertz (Hz) to 8000 Hz. As you move along the scale from left to right, sounds become higher pitched.
Vertical axis: This axis shows the intensity, or loudness of sounds, measured in decibels (dBs). The top of the graph indicates softer or quieter sounds, while the bottom shows louder sounds.
Symbols and Their Meanings
The audiogram uses specific symbols to indicate hearing levels. These are as follows:
Air conduction testing: This test registers the sounds moving through the ear canal. Results for the right ear are marked on the chart with a red O while those for the left ear are usually marked with a blue X.
Bone conduction testing: This test involves the transmission of sound through the mastoid bone and will be marked with symbols.
Understanding Audiogram Results
An audiogram features a designated area which represents standard hearing health. If your symbols fall within the said area, your hearing is considered to be within normal limits; symbols outside of the area indicate that there is hearing loss at the frequencies indicated on the chart. Hearing loss is classified with reference to where the symbols are positioned.
Mild hearing loss is indicated when the symbols are just outside of the indicated area on the chart. If the symbols are further outside of the area designated as normal, then you may be informed that you have moderate hearing loss. At the very bottom of the chart is the area indicating severe to profound hearing loss. Profound loss is defined as when a person is unable to hear any speech and can only hear very loud sounds.
Hearing Aid Styles and Types
For those who are experiencing hearing loss, there are definite benefits to using a hearing aid to regain your ability to hear. There are various kinds of hearing aid available, of which the following are the main examples:
In the ear (ITE): These hearing aids are custom-made to fit into the outer bowl of your ear, snugly to prevent any sound from leaving. These are suitable for mild-to-moderately-severe hearing loss.
Behind the ear (BTE): BTE hearing aids sit behind or on top of the outer ear, using tubing to route the sound down into the ear canal. These are for individuals experiencing mild-to-profound hearing loss.
In the canal (ITC): Custom molded and designed to fit partly in the ear canal, these hearing aids offer a discreet solution which is often favored by wearers. These hearing aids are suitable for mild-to-moderate hearing loss.
Taking the Next Step
Understanding your hearing test results is the initial step in addressing any loss of hearing. If your results show any hearing loss, it is then time to consult with an audiologist. They will be able to interpret your results and offer you guided advice on the potential treatments, including which style of hearing aid would be best for your needs and they can also begin the process of fitting you for the right hearing aid to enhance your auditory outcome.
A hearing test will provide an in-depth evaluation of the health of your hearing. By understanding how the test works and how to read an audiogram, it is possible for you to take proactive and successful steps to ensure the optimal results for your hearing health. This will have the benefit of maintaining your natural hearing for as long as possible and enhancing your ability to hear.
