Sound engineer – dB Volume Review

Nice meter, but sensitivity is way off. The A weighting is 3db low, the B weighting is 10db low, the C weighting is 15db low. I checked with a calibrated Simpson 886 sound level meter. It would be nice if a calibration feature was included so that it could be adjusted to agree with a professional meter. With a C noise level of 50db, this meter says it's 35db.
