Professional Sound Meter

Professional Sound Meter is a sound/noise detection and measurement tool for your Android phone or tablet.

What makes Sound Meter professional is its high accuracy in interpreting signals coming directly from the microphone hardware of your device. You also get dB values along with raw noise levels data.

Professional Sound Meter lets you choose from 5 different refresh rates, depending on the accuracy you need. Furthermore, you get 3 visual indicators, each working with a different sensitivity level.

First Indicator - High sensitivity (for quiet sounds)

Second Indicator - Medium sensitivity

Third Indicator - Low sensitivity (for louder sounds)

Despite being a valuable and free professional tool, this app features a modern looking style and follows Android's material design guidelines.
