Decibel Meter is an app that will help you measure the ambient noise level in real time and the duration of sound exposure of various intensities over a user-defined period of time. The application calculates acoustic intensity in decibels and displays a detailed visual report on the screen of your digital device.

For the Decibel Meter to work correctly and detect the noise level, you need to allow access to your device’s microphone. Audio data read by the microphone is displayed in decibels (dB) in a user-friendly style.

• Real-time decibel (dB) meter;
• Minimum (MIN), average (AVG), maximum (MAX) sound level display;
• Fully functional noise dosimeter compliant with NIOSH and OSHA standards;
• Photo and video with noise overlay;
• Option to stop and record measurement results at any time;
• Data saving feature.

The app will help you avoid noise pollution and will protect both your health and the health of your family!

Works fine, this was the only way to read an out of print issue that was sold out in the Decibel store and not available on Ebay.

Not sure how to use the camera. Everything else works perfectly.

Hello, thank you for your positive feedback 😄 The Decibel Meter allows you to quickly take photos and overlay dB measurements. Taken photos can be easily shared through popular social networks. This should be very helpful to let your friends and family know the noise around you! In order to take a photo with dB measurements overlay, you need to give the application permission to use the camera.
