Sound Level meter calibration.
We calibrate the sound level meter which are tested for frequency response of microphone and filters, the different time weightings (fast, slow, etc.), level linearity etc. We calibrate the sound level meters at start points at 74 dB, 84dB, 94 dB, 104 dB & 114 dB @ 1KH2. Our world class reference standard is directly traceable to NPL, Delhi.
