Sound Detector & Noise Detector is a free Android application developed by Sparkling India in the Social & Communication category. It is a tool app that helps you understand the sound quality and sound decibel. This app works as a decibel meter that uses your phone's microphone to measure environmental noise and calculate its value in decibel unit (db). The app can detect various sounds, including acoustic, and can be used to measure too loud or too low sound.

The app displays the decibel value with a running graph line, indicating the minimum, average, and maximum decibel value. It also displays the elapsed time, noise information, whether it is good or bad for human health, and the option to play and pause sounds. The app is easy to use, and changing settings is effortless.

Sound Detector & Noise Detector can also be used as a sound level meter or frequency meter to detect high pitch sounds, which are harmful to mental health and human hearing functionality. However, the app may not recognize very loud sounds (over 90 dB) in most devices as microphones in most Android devices are aligned to human voice. Therefore, it is recommended to use it as an auxiliary tool.

Overall, Sound Detector & Noise Detector is a useful app for measuring environmental noise and detecting harmful sounds.
