Sound level meter (or SPL - sound pressure level) is an app which can measure the actual sound level meter with decibels (dB).
Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).
Sound meter application uses the microphone to detect sound and convert it into an SPL value. The range between the noise floor and saturation may be only 20 dB on the worst devices, but could exceed 100 dB on the best devices.
If you have professional sound meter and our noise measurement is not exactly equal - you can calibrate our SoundMeter tool. For the basic usage our app is fully sufficient! If you want you can also change measuring frequency.
With Sound meter you can measure sound when you at home and prepare for baby sleeps, so keep it quiet.
Or you can use it to test car noise when buying a new one.Many things you can do with this sound meter app.
