Are you looking for a tool to measure sound level and measure environmental noise? Sound meter: decibel meter is a free app to detect sound and measure its decibel value (db value). Sound meter db noise detector uses phone built-in microphone to measure sound in decibel and also display it in simple graph.
Sound detector is also called sound meter or decibel meter (db meter). Through Sound detector or noise detector you can easily detect very loud sound or very low sounds in order to protect your hearing functionality from too low or from too loud sounds.
Spl meter (Sound level meter) app display decibel values by measuring the environmental noise and it show the measured db values in various different forms. It is also very helpful app to detect environmental noise from your surroundings.

Key Features:
• Indicates decibel by gauge
• Display min avg and max db values
• Display decibel values by graph line
• Can calibrate the decibel for each device
• Division Gage
• Display Measure Time
• Calibration Decibel
• Refresh Play Pause


Db Noise detector or Spl meter uses phone microphone to measure environmental noise in decibels. The db value of decibel meter app might be vary compare with real sound meter or sound detector device. Now noise measurement can easily be done on mobile phone.
Sound level meter also called frequency meter or sometime may be called as spl meter. Too noisy sound is harmful to hearing functionality. Protect your family health from very loud sounds or noise by using decibel meter or noise meter to detect db value or to measure any environmental noise because we know that environmental nose is very hazardous for both human physical and mental health.

Note:
- Sound detector (db meter) uses phone microphone to measure too noisy sounds. In most android devices microphones are aligned to human voice.
Sometime db value over 90 may not be recognized by most device so please use it as an auxiliary tool. Sometimes the decibel value calculated by noise detector is not as accurate as an actual noise meter and this is due to some smart phone devices microphone are aligned to human voice.
