Sound Meter - Measure Sound Pressure Level
Sound Meter, also known as SPL (sound pressure level) meter, is a free Android app developed by Netigen Tools. This app measures the actual sound level in decibels (dB) using your device's built-in microphone. It can be used as a noise meter, sound level meter, or sound pressure level meter.
The app provides a reference for the sound level and has been calibrated with an actual sound level meter on various Android devices. However, it's important to note that the built-in microphones are aligned to human voice (300-3400Hz, 40-60dB) and have hardware limitations. This means that very loud sounds (100+ dB) cannot be recognized.
Sound Meter is a fun and useful auxiliary tool for measuring sound levels. It can help you determine the noise levels of your surroundings and the potential risks to your hearing. The app also provides a guide to the levels of noise in decibels (dB) according to the American Academy of Audiology. If you have any problems, you can contact the developer at
