Sound Meter APK for Android

Sound Meter is a free Android application that accurately measures sound pressure levels in decibels (dB) using the device's built-in microphone. This utility is ideal for users looking to assess ambient noise levels in various environments, serving as a noise meter or sound level meter. The app's calibration aligns it with actual sound level meters, ensuring reliable readings for everyday use. It is particularly useful for monitoring noise exposure and understanding potential risks to hearing health.

The application offers a user-friendly interface and includes a reference guide on decibel levels, adhering to guidelines from the American Academy of Audiology. While Sound Meter provides valuable measurements, it is important to acknowledge the limitations of built-in microphones, which are optimized for human voice frequencies and may not accurately capture very loud sounds exceeding 100 dB. This makes it suitable for general noise monitoring rather than professional sound analysis.
