Why Do Some Toys and Kids' Headphones Have a Volume Limit?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do some toys and kids' headphones have a volume limit?

The Big Idea

Some toys and kids' headphones have a volume limit to protect young ears! Many have a limit of about 85 decibels, and some use lower limits. A limit stops the sound from going any louder.

Decibels

Step one: decibels. Loudness is measured in units called decibels, written dB. Higher numbers mean louder sounds.

A Safety Limit

Step two: a safety limit. Many kids' headphones stop the sound at about 85 decibels, and some use lower limits. Loud sounds can harm young ears, and kids may not notice when something is too loud.

Still Go Low

Step three: still go low. A limit is like a safety net, but it is still good to listen at a low volume. Some phones let a grown-up set a volume limit as well.

A Closer Look

Let's take a closer look! Look for a number like 85 dB. The limit stops the sound from going higher. Phones can have limits set by a grown-up. But a low volume is still the best. Safety nets help, but you help too.

Quick Facts

Quick facts! Quick facts about decibels. A whisper is about 30 decibels. Normal talking is about 60 decibels. A lawn mower is about 90 decibels, louder than the limit. Fireworks and sirens are louder still.

Think Like a Scientist

Now, think like a scientist! With a grown-up, look at a headphone box or manual for a number like 85 dB. Compare it with a loudness chart. Which everyday sounds are louder than the limit? Share what you discover with a grown-up.
