分贝仪，噪声器 is an all-in-one acoustic utility that combines a high-precision decibel meter with a versatile noise generator. The app monitors ambient sound through your phone microphone in real time, displays waveform charts and keeps historical readings so you can quantify noise levels at home, in the office or on the go. It also offers white noise, pink noise and pure-tone generation to mask distractions for sleep or focus, test speaker and microphone response, and perform basic hearing checks—useful for anyone who wants to manage their sound environment and protect hearing.
Key Features
