What is a decibel why is it important?

Answer 1

Decibel is the unit in which we measure how loud a sound is. Whenever we want to be able to say if something is too loud (like an industry next to a residential area) or too quiet (like a fire alarm siren) we need something like the decibels to know what we're talking about.

Answer 2

A decibel is a unit used to measure the intensity of sound. It is important because it allows us to quantify and compare different sound levels, from very quiet to very loud, in a uniform way. This is crucial for protecting human hearing, setting noise regulations, and evaluating the impact of sound on the environment.
