This app measures and displays the ambient sound pressure level in decibels (dB SPL) using your device's internal microphone. It offers a stylish analog display and allows you to capture photos with the sound level data embedded.
Key features include a smooth analog display of dB(A), the ability to take photos with the sound level displayed, and options to share, print, and store these photos. With an in-app purchase, you can also select frequency weightings (A, C, Z) and record decibels on annotated strip charts.
The core functionality of the app, including the analog dB(A) display and photo capture, is free. Advanced features such as selecting frequency weightings and recording decibels on strip charts require an in-app purchase.
The app uses the internal microphone of your mobile device to estimate sound pressure levels. Specific compatibility details regarding operating system versions and hardware requirements are typically found on the app store listing.
Common use cases include checking noise levels in restaurants, trains, or offices, assessing the quietness of a bedroom at night, or understanding the sound levels of everyday appliances like vacuum cleaners. It's useful for anyone curious about their acoustic environment.
