Every now and then, your doctor may ask you to get a hearing test. Don’t assume that something is wrong. Hearing tests are how doctors use to make sure that your ears work well.

Hearing tests measure how well you are able to hear. Normal hearing happens when sound waves travel into your ear, causing your eardrum to vibrate. The vibration moves the waves farther into the ear, where it triggers nerve cells to send sound information to your brain. This information is translated into the sounds you hear.

Hearing loss is common in older adults. About one-third of adults over the age of 65 have some hearing loss, most often the sensorineural type. If you are diagnosed with hearing loss, there are steps you can take that may help treat or manage the condition.

Some people may suspect that they have hearing loss. They have trouble hearing people talk to them when they’re in a crowded room, or they’ve been told they raise the volume on the TV way too high.

But not all people know that they have a problem. You may not realize that you have hearing loss, because it’s often a gradual process. That’s why it’s important to have your ears checked when your doctor says you should, even if you think you’re fine.

Most adults who get hearing tests are asked to wear earphones and listen to short tones that are played at different volumes and pitches into one ear at a time. Whether or not you can hear each sound shows whether or not you can hear high-pitched or low-pitched sounds, quiet or loud sounds, and whether your left or right ear has hearing loss.

During some hearing tests, you may also be asked to listen to speech at different volumes, which will be played into one ear at a time. The voices will be played quietly through your earphones, and you’ll be asked to repeat what words were just said. This test is done in a soundproof room, since some people have trouble hearing voices when there’s background noise.
