In this article we will teach you how to measure the volume of sound , commonly called noise, with an Android cell phone. We will also explain some interesting facts about this phenomenon that surrounds us.
Some basics about sound
Sound is produced when we exert pressure on the air molecules that are around us. The higher the pressure exerted, the greater the volume. To measure the intensity of the acoustic pressure of sound, a sound level meter is used . And the unit of measurement is the decibel (dB), which is one-tenth of a Bel. It was named in honor of Alexander Graham Bell, inventor of the telephone.
A sound of 75 dB is already starting to be harmful. From 120 dB a sound begins to be painful. For this reason, it is important to control the intensity of the noise in our environment, as our health depends on it. That is why experts do not recommend increasing the volume of the mobile to the maximum .
In fact, there are some apps that are used to control the volume of the mobile in each application , which is a good way to protect your ears from the sounds of the mobile.
How to measure decibels with your mobile using the best apps
Currently there is no native Android application that fulfills this function. Therefore, the first thing you will have to do is log into the Google Play Store with a Gmail account and download an application that allows you to measure the decibels or the amount of noise in your environment.

Before starting the analysis, keep in mind that the microphone of mobile phones is designed to work with the range of the human voice . For that reason, when using any of these applications do not expect professional results. Although for high decibels it will not give an exact measurement , it will serve to give you an idea of the volume of the noise around you.
