If your neighbor is making noise at odd hours, or you want to know how annoying the noise is of the washing machine Or you're just curious to know how isolated a room or instance is, don't forget that you have all the technology you need you need in your pocket. Your mobile has a good microphone that not only helps communication, picking up your voice and sending it in the form of call or audio message from WhatsAppIt can also be used almost at a professional level to detect sound volume or ambient noise All you need is an application capable of measure decibels
The application Sonometer is focused on meeting these user needs. Of course, as its creator remembers, it is not a professional tool And it is that most mobile phones Android have a microphone calibrated for the sound of the human voice, so loud noises (around 90 dB) may not be measured with complete precision Thus, it is a tool not entirely reliable depending on what situations or noises are measured. If it is to detect the volume of a noise that is not deafening or to know the level of silence of a room , is a more than capable tool.
Set Sound Level Meter
As soon as you start it, a message in English informs us about the exclusive configuration of each microphone . In short, Sound Meter wants the user to calibrate their microphoneto be as exact as possible. To do this, all you have to do is Move to a quiet place, where there is no noise, and set the base value of the meter between 10 and 20 decibels From From this moment it is already possible to use the application and do it in a reliable and correct way

A representation shows at all times the decibel level picked up by the mobile's microphoneIt is a really sensitive sensor, so it is possible to see it in constant movement just by moving the mobile in the air Under the numerical figure, a brief description helps to understand the value of those decibels with terms like: quiet library, conversation, rustling leaves, loud music, etc.
Another graph, at the bottom of the screen, shows the noise history In this section both the decibels as the seconds, something that helps to see, at a glance, if thesound is continuous or punctual
As points extras, this application has various modes of representation of its data. On the one hand there is the night mode, that modifies the elements in white and shows them in black.This avoids the inconvenience of a bright screen at night, for example.
