Sound Meter app

/
/

Sound Meter is in the 4th set of the Smart Tools collection.

Have you ever suffered from the noise of the neighbors?
SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. I had calibrated a lot of android devices with an actual sound level meter (dBA).

REMEMBER!! Most smartphone microphones were aligned to human voice (300-3400Hz, 40-60dB). Voice calls do not require high-performance microphones.
Therefore the maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. Moto G4 (max.94), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)…

See 6-7th images. I calibrated major android devices with an actual meter. You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.
