Hearing: How Accurate Is Audiogram?

If you are experiencing hearing loss, it is important that you see an audiologist right away to get tested. There are a number of different types of hearing tests that audiologists use to determine whether you have hearing loss and, if so, how severe it is. The results of the test can then be used to help the audiologist find you the best possible treatments. 

An audiogram is one of the most common ways that the results of a hearing test are measured and analyzed, but many people are concerned about how accurate it is. Read on to learn more about how an audiogram works and how accurate it is for assessing hearing loss. 

What Is an Audiogram?

An audiogram is a special type of graph that shows how well you can hear sounds at different frequencies. When you visit an audiologist for hearing loss, they will test your ability to hear noises at several different decibel levels and then plot the results on an audiogram. This will provide them with information about which parts of your ear are not working properly or whether you have some damage due to loud noise exposure.

What Are the Different Types of Audiograms?

There are different types of audiograms that can be used depending on why you scheduled the hearing test. These types include: 

  • Pure Tone Air Conduction (PTA): This measures sound that travels toward the ears from speakers directly in front of you.
  • Bone Conduction (BC): This measures sound that travels through the bones of your skull to get into the inner ear.

Once the results of your hearing test are plotted on an audiogram, your audiologist will have a clear picture of your hearing loss and how to manage it properly. 

The Benefits of Audiograms

An audiogram is a critical tool for an audiologist to use when creating your treatment plan. This simple graph can tell them all kinds of information about the condition and severity of your hearing loss and help them choose the most effective course of treatment. For example, if you have trouble hearing higher frequency sounds, they may suggest using a special type of hearing aid that amplifies these tones specifically. Having detailed information about the exact nature of hearing loss means that an audiologist can provide the best possible treatment and protect your hearing in the future. 

How Accurate Is an Audiogram?

There are several things that could influence the accuracy of an audiogram, but when you visit an audiologist for testing, they use several different methods to ensure the results are reliable. Some factors include: 

  • The size and make-up of your ear canal: Your ears come in all shapes and sizes, which means it may be difficult to get a clear measurement with certain brands or makes of equipment. 
  • Your age: Audiograms can be a little less accurate in very young children because their ear canals have not fully developed yet. In older adults, hearing loss caused by age is only expected to increase, no matter what type of equipment is used.

However, audiograms are still incredibly accurate and they remain one of the best ways for an audiologist to measure hearing loss. Although other types of hearing tests are available, an audiogram is the go-to option, in most cases. 

If you have noticed a change in your hearing and you are concerned that you may be experiencing the early stages of hearing loss, you should see an audiologist right away. They can carry out a hearing test and use an audiogram to assess your hearing ability. Identifying hearing loss issues early is the best way to treat them effectively and prevent further degradation in the future. So, if you have any concerns, no matter how small, always seek the advice of an audiologist.
