Sound Meter Master is the most advanced tool to measure sound level and pressure. It can be used to detect the noise level of any environment, from a quiet room to a noisy street.

This handy tool will let you know exactly how loud the sounds are in the current environment, and you can use it as a noise level meter, sound pressure level (SPL) meter, or even a decibel meter.

What's more, this handy tool lets you save the data you record and display, so you can view and analyze it later. And you can use it offline!

You can also record and view the sound spectrum and its graphical representation, so you can understand what you hear and how the sound waves are formed.

You can use the app to measure the noise level in different environments and get the results in decibels. And the results you get can be displayed in dB or decibels.
