Sound waves are produced any time an object moves or shakes. These are waves that travel through the air and reach their ears. If you think about a guitar string when someone plays it, it vibrates really fast back and forth and that creates music! Or when you speak, your voice box vibrates and produces sound waves.
And scientists measure loudness using a special scale. It is called decibels, or dB for short. A long time ago, a clever man called Alexander Graham Bell for example came up with this method of measuring sound. Bell is best known for inventing the telephone, but we use his concept to describe loudness.
Imagine if you had something that could tell you exactly how loud a sound is. That's what a dB meter does! The meter converts sound waves into a number when sound waves strike it. The larger the number, the greater the noise. It’s like a guide who helps us with the information that goes too loud.
It is crucial to know how loud things are, especially to protect our ears. Our ears are very special, and they may get hurt if sounds are too loud. Just like we put on sunscreen to protect our skin, we need to protect our ears from super loud sounds.
We see dB measurement used in many interesting places! They control it at the movie theaters as well — not too quiet, not too loud. In large constructions sites, workers have special equipment to measure how noisy their machines are. Even musicians use these tools to ensure that their music is finely tuned.
There are many different types of sound measurement tools. Some are small enough to be held in the palm of your hand. Others are larger with many buttons and screens. What do people want to do, and how do they choose the right tool for it? Is it like choosing the correct tool in your dad’s toolbox?
First, we need to know sound and sound level to help keep our ears healthy and happy. Whether a concert, classroom full of kids, or a busy street, understanding sound allows us to keep our friends and family safe and experience life around us to the fullest.
