Children And Hearing Protection: What You Should Know
The world is full of loud noises, but some are particularly problematic for kids.
A child’s ear canal is smaller than an adult’s, so the sound pressure generated is greater than in an adult’s ear. This means that loud sounds are even louder for small children. Their internal ear structures are fragile, more sensitive, and especially prone to noise-induced damage.
Here are a few common causes of hearing problems for children:
Loud toys – Noise-making toys are popular, but some might do their job too well; some can produce sounds above 120 dB! If it’s too loud for them to hold it next to their ear, think twice before buying or letting them play with the toy.
Television volume – People tend to turn up the volume when watching television. This can sometimes be too loud for adults, let alone children (who can crawl close to the speaker).
Events – Concerts, festivals, and sports events can be exciting and educational places to take your kids. They can also be very loud!
Firework displays – Firework displays are guaranteed to be noisy, and short bursts of loud noise can still cause permanent hearing damage to adults and children alike.
Household appliances – be careful not to use loud household appliances such as the vacuum, hairdryer, or blender too close to your children. Adults are used to these noisy home appliances, but they’re loud enough to damage your child’s hearing.
White noise sleep machines – if you want to use an infant sleep machine test the sound output before leaving it in your child’s room, place it as far away from them as possible, and use the lowest volume setting.
How Loud is Too Loud?
Sounds are measured in decibels (dB), and generally, noises under 80 dB won’t harm a child’s hearing unless they are exposed for many hours. What is deemed a ‘safe’ sound is based on the duration of exposure, and it’s a good general principle to reduce your child’s exposure to any loud noise as and when you can.
Nevertheless, it should not be forgotten that even very short bursts of extremely loud noise can cause permanent hearing damage.
Monitoring your child’s environment and being aware of the sounds that they are regularly exposed to is a crucial part of minimizing your child’s exposure to loud noise. When noise is unavoidable, ear protection is your next best option.
It’s important to keep in mind that the hearing damage caused by noise exposure is permanent (there is no way to ‘cure’, reverse, or completely treat the damage caused) and cumulative, meaning even one-off loud noises can eventually contribute to overall hearing loss.
