What Is Hearing Loss?
Hearing loss makes it hard to hear or understand sounds. This happens when there is a problem with one or more parts of the ear, the nerves coming from the ears, or the hearing part of the brain.
Some people are born with hearing loss. But hearing loss may come on slowly over time or show up later in life. Hearing loss runs in some families, or may be caused by a birth defects, infections, or medicines that damage the ear. You can’t prevent these kinds of hearing loss.
But you can do something about noise-induced hearing loss. A sudden loud noise (like an explosion) or being around loud sounds over time can damage the tiny hair cells of the inner ear, making it hard to hear. If the noise around you is so loud that you must shout to be heard or you can’t hear the people around you, there is a chance that you’ll have some trouble hearing.
Have you ever heard a ringing or buzzing sound in your ears after going to a party, concert, or other really loud event? This is called tinnitus (pronounced: TIN-ih-tus). It usually gets better over a day or two. But tinnitus or a muffled feeling in your ears is a sign that there is some damage to the hair cells in your ear. Hair cells take sound waves and change them to electrical signals that are sent to the brain. When the hair cells are damaged, they can't send sound signals as well as they did before.
Tinnitus and hearing loss may not go away if you listen to loud music or hear loud sounds over and over again. That's why construction workers and airport workers wear ear protection. Lawn mowers and power tools, like chainsaws, are loud enough to cause tinnitus and hearing loss.
Listening to loud music a lot can cause problems over time, especially if you use headphones or earbuds. Some musicians have lost their hearing and have tinnitus — a real problem for someone who needs to hear to make music. That's why you may see more musicians wearing ear protection while they're playing.
How Can I Prevent Noise-Induced Hearing Loss?
The best way to prevent noise-induced hearing loss is to protect your ears from loud noises:
- Move away from loud sounds or speakers.
- Turn down the volume when listening to music or watching TV. When wearing earphones or earbuds, you should be able to hear conversations around you.
- Take breaks after listening to music with headphones or earbuds for more than 1 hour at a time.
- Wear ear plugs at concerts or if you play in a band.
- Wear ear plugs or ear muffs when mowing the lawn, using power tools, or anytime you are around loud machinery.
- Talk to your doctor about getting a hearing test if you have tinnitus that doesn’t go away or you are concerned about your hearing.
