Do you wonder how noisy things are? How do you like finding out about sound measurement? Renyuan is here to solve that problem for you! In this guide, we will cover some basics about decibels and teach you how to measure sound like a pro! Explorations involving sound can be pretty great, and they can help us make sense of sounds we experience daily.

Decibels are a special kind of unit which allow us to break down sound. They show us just how loud — or quiet — something is. A quiet room with a few people reading, for instance, might register about 30 decibels. Conversely, a loud rock concert with thumping booming music can hit 120 decibels! Why It Matters Measuring sound sounds like an odd thing to do, but being exposed to loud noise over time can damage our ears, leading to hearing loss.

Tools and Techniques

This tool is really cool! It can determine the pitch of a sound and display it to us in units called decibels. It does this by a converting sound waves found in the air into numbers that can be visualized on a screen.

A simpler way to hedge trimmer is with a smartphone app. There are tons of apps out there that are either free or extremely low-cost. These apps lend themselves to quickly and easily measure sound levels. Just make sure you bring your phone close to the sound you’re trying to measure for accurate results.
