Sound Meter Pro v2.4.9

<br>

<br>

<br>

<br>

<br>

<br>Sound Meter Pro is the 4th set of Smart Toolsآ® collection (noise, vibration, seismometer).

<br>

<br>SPL(sound pressure level) Meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. We had calibrated many Android devices with the actual Sound level Meter with dB(A).

<br>

<br>REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB).

<br>Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB), HTC Desire(82dB)...

<br>

<br>Vibrometer app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seism detector.

<br>

<br>The measured values are the Modified Mercalli Intensity scale(MMI), and just for reference.

<br>If it is inaccurate, you can calibrate it so that the maximum value is about 10-11.

<br>
