What Can You Expect to Discover From a Hearing Test?

The majority of people aren’t proactive about the health of their hearing and probably haven’t had a hearing screening since grade school because it’s usually not part of a routine adult physical. Fortunately, a professional hearing specialist can uncover a wealth of information from a hearing examination which can be used to both identify any hearing loss and help determine whether using treatments like hearing aids is effective.

A complete audiometry test is more involved than what you may remember from childhood, and you won’t get a lollipop or a sticker when it’s completed, but you’ll gain a much clearer understanding of your hearing. There are three common types of hearing tests, each of which will supply different perspectives about your hearing.

Pure tone testing

We typically think of sound as measured in decibels, but decibels only express the intensity of a sound. Another important factor is pitch or tone which assesses the frequency of sound. At the lower end of the tone spectrum, a low bass sound measures between 50 and 60 Hertz (Hertz, or Hz for short, is the unit of measurement related to tone or pitch), with normal speech ranging between 500 and 3,000 Hz. Healthy human hearing ranges from 20 to 20,000 Hz.

For pure tone testing, you’ll wear headphones or earphones connected to an audiometer. Another device that your hearing specialist might use is known as a bone oscillator which just measures how well sound is conducted by your bones. A lot like that familiar hearing test from your youth, you press a button or raise your hand when a tone plays either in your left ear or your right ear.

The minimum volume that you can hear the tones will then be monitored. Whether your hearing loss is more pronounced on one side than the other, what frequency of sound you have the most trouble hearing, and generally how well your ears are functioning, will be gauged by this test.

Speech audiometry

This type of test evaluates your ability to accurately hear spoken words, again with sounds being played through headphones. Your hearing specialist will sometimes ask you to repeat recorded words that you hear while there is background sound. In other cases, the person performing the test will say words to you, but there’s a surprise, you can’t see the person’s mouth.

Because you can’t see the speaker’s lips, you won’t get any visual cues to help you, and because they are only speaking single words, you won’t have any context to fall back on. Rhyming words, let’s say crime, time, dime, and climb, can be hard for individuals suffering from high-frequency hearing loss to differentiate.

Speech audiometry monitors your ability to make sense of what you’re hearing unlike tone testing which measures how loud particular sounds have to be in order to be heard. Whether hearing aids will be helpful is another thing that word recognition testing can help identify.

Immittance audiometry

This type of testing normally won’t cause pain, but it might be a little uncomfortable. In tympanometry, a little probe is inserted in your ear, and air flows through it to artificially change your ear’s pressure. A graph readout will permit your hearing specialist to identify if there’s a problem with your eardrum such as earwax impaction or a perforation, and how well your eardrum is functioning.

Your ears have reflexes that are tested by a similar probe. Muscles in your ear involuntarily contract when you are exposed to loud noise. Knowing the noise level required for this reflex can help a hearing specialist measure the extent of hearing loss. People with extreme hearing loss don’t exhibit any reflex.

It’s important to include immittance testing because it helps diagnose conductive hearing loss, which is when issues happen in the small bones inside of the ears and can happen at the same time as age-related or noise-related hearing loss.
