Sound Meter

SPL (sound pressure level) meter app uses your microphone to measure noise volume in decibels (dB), and shows a reference.

• Real time decibel graph
• Display the current noise reference
• Display Average/Leq, Min and Max values

Please note: most smartphone microphones were aligned to human voice (300-3400Hz, 40-60dB), therefore maximum value is limited by the manufacturers, and very loud sound (100+ dB) cannot be recognized. You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.
