HONEST ABOUT ACCURACY
Sound Gauge Pro uses IEC 61672 A/C-weighting filters for frequency correction. Readings are approximate (±3 dB) due to device microphone limitations. For regulatory or
professional measurements, use a certified sound level meter.

One price. No tricks. Just a great decibel meter.
