About this app

Sound meter is an indispensable tool for your daily life, no matter what you do, where you stay, it is a practical noise detector to help you avoid noise pollution that harms your hearing and affect your rest. Our sound meter app can provide accurate decibel data and show you how the decibel goes.

Get noise data more comprehensively and more accurately:
Minimal, average and maximal decibel
Real-time decibel in dial and graph
Levels of noise
Calibrate before use for precise data
Review measurement histories

Customize your sound meter
Save audio file while measuring
Set decibel warning when the value is higher than the preset one
Open the sound or vibrate for the warning
Apply the black or white theme

Other features of sound meter:
Re-start measuring
Suspend recording
Rename, share and replay the recording
Indicate the measuring duration, time and status

1.To get an accurate decibel of sound with this decibel meter (noise meter), please calibrate before use (because the performance of the microphone will be different for each device). 
2.Adjust the decibel according to your experience or calibrate with a real sound meter device for comparison. (Because we couldn't estimate the different decibel between devices, we do not provide a specific solution.)
3.To avoid unnecessary loss, please SAVE your recording before exiting the sound meter app
4.If the recordings are not saved, you cannot replay the measurement.

If you have any questions, please contact us by email.

When saving and reviewing history, there is no ability to review the file to see where the peaks in noise occurred and to skip to that portion of the recording. It purely saves just an audio file that can only be played from the beginning in real-time. No ability to see the chart of noise level over time or ability to skip around in the audio file, which ends up making it kind of worthless.

Unless you need very specific/professional measurements just get this. Make sure to calibrate it. UI is intuitive. It gives z weighting which is all i need. I can just plug the data into a computer/spreadsheet if i'm going to be doing any data analysis. And provides a way to get rid of ads for free while supporting the devs! All of the others just want to steal money from you. $3 for A weighting? So expensive. A weighting only works well for sound that isnt very loud.

Excellent! This app does what it says. Ads aren't invasive and don't interfere while running the app. Wish there was some way to see the sound graph spikes when you save audio files. I'm not sure if i am calibrating correctly. Do you adjust the level to match with what the meter says? Or do you set it to the decible level you want the microphone to pick up? I was playing around with this and it recorded the neighbors conversation in the house next to mine. Made my mic on phone more sensitive.
