How to Help Protect Your Child’s Hearing

Loud sounds are everywhere. About four in 10 young people have been around dangerously loud noises. But what noises are unsafe? Can you help protect your child from them? You can! Read on for information about noise-induced hearing loss (NIHL), and what you can do about it.

HOW NOISE-INDUCED HEARING LOSS CAN HAPPEN

The world is made up of many different sounds. Most sounds are safe for hearing, but some sounds can damage hearing if they are too loud or are loud enough for an extended amount of time. 

When sounds become harmful to hearing, a person can develop noise-induced hearing loss. NIHL can happen at any age. More recently, it has become more common in children. 

NIHL is permanent, but it can be prevented.

DANGEROUS VS. SAFE SOUND LEVELS

Sound is measured in decibels (dB). The series of decibels can range from negative numbers (soft sounds) to numbers over 100 (loud sounds). As the number of decibels grows, the sound gets louder. 

Here are examples of various sounds and how soft or loud they typically are:

  • Birds chirping 30-40 dBA
  • Conversation 50-70 dBA
  • Movie theater 80-105 dBA
  • Gas lawn mower 90-110 dBA
  • Concert 90-120 dBA
  • Sirens 100-125 dBA
  • Fireworks 130-150 dBA 

When loud sounds travel through the ear, they damage hair cells in the inner ear very quickly. This causes NIHL. Once these hair cells are damaged, they cannot repair themselves.

WHAT SOUNDS ARE HARMFUL TO HEARING?

Sounds are most likely to cause damage to hearing if:

  • They are loud sounds that happen over a certain amount of time. Example: Going to a concert. 
  • One very loud sound or “impulse noise” takes place. Example: An explosion. 
  • You take part in certain recreational activities. Examples: ATV riding, listening to music too loud with headphones, target shooting, playing in a band, attending loud events, or completing household chores such as mowing the lawn. 

Sounds at 70 decibels (dBA) or lower are usually safe to listen to for any amount of time. 

Sounds at 85 decibels (dBA) can lead to hearing loss if a child listens to them for more than 8 hours. 

The louder the sound is, the less time you can listen to it safely. For example, listening to sounds at 90 dBA for a few hours will do the same damage as listening to sounds at 110 dBA for 2 minutes.

You may want to use a sound level meter app on your phone. These apps measure the noise levels of various activities your family might take part in. They can give you a quick glance at how loud of a setting you are in. There are several of these meters available for free wherever you find your apps.

COMMON SYMPTOMS OF NIHL 

These symptoms can happen gradually or suddenly.

  • Long-lasting hearing loss
  • Temporary hearing loss
  • Having a hard time understanding others
  • Ringing or clicking in the ears (called tinnitus)

4 WAYS TO PREVENT NOISE-INDUCED HEARING LOSS

  1. Turn down the sound.
  2. Walk away from the sound.
  3. Limit the time spent with the sound.
  4. Wear hearing protection.

Keep Noise Down at Home

  • Lower the volume of electronics to the softest volume that they can be heard clearly.
  • Find ways to make chores quieter, for example, close the doors between the laundry room and the rest of the house.
  • Buy quieter toys and be aware of the noise rating of toys.
  • When shopping for appliances, choose models that have a quieter noise rating.
  • Use soft furnishings indoors to soften noise, such as putting carpets over hard floors.

Keep Noise Down When You’re Out and About 

  • If you’re with your kids in an area where there is loud noise (group of loud cars or motorcycles rides by), cover your ears and have your kids do the same. 
  • Take earplugs for the whole family to loud events (a fireworks show, car race, or concert). 
  • Take note of where speakers are set up at events, and avoid sitting or standing right next to them.

Talk to your kids about the damage loud sounds can cause. This is especially important as your children get older, start wearing earphones and enjoy turning up the music. (See our blog post on How to Listen to Earphones Safely.) Once noise-induced hearing loss happens, it can’t be reversed. 

CHOOSING HEARING PROTECTION

Hearing protection helps protect children’s ears from loud sounds that can damage hearing. It lowers the loudness of sounds going into the ear, but does not totally block out sound. The most common types of hearing protection are earplugs, earmuffs and specially made devices. 

Kids most often wear earmuffs to protect their hearing. Make sure they fit well. Hearing protection that does not fit properly will not protect your hearing. 

  • Choose hearing protection that is comfortable and convenient – You’ll be more likely to wear hearing protection that is a good fit.
  • Be a role model – Children look up to adults and their actions. It is important that adults are consistent in how and when they wear their protectors.
  • Go shopping together – Children will be more excited to wear their hearing protection if they help pick out the style and color.
  • Set clear rules – Tell children the expectations for wearing hearing protection. Talk about the places where wearing hearing protection would be important. 
  • Choose the right protection – Children may not want to wear their hearing protection if it makes it too difficult to hear other sounds around them.
  • Make sure hearing protection is ready to use – Wearing protection every time you are around the noise affects how well it works.
