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 G3 (max.80), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)...
See 6-7th images. I had 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.
