Gracey & Associates Hire and Calibration
Noise Meters, Noise Measurements
Full range of noise meters for noise measurement and acoustic analysis in accordance with the relevant
British & International Standards.
The most popular meters, we hire for noise surveys, are the Norsonic 116 and the B&K 2236. Where octave and 1/3 octave band surveys are required, the B&K 2250, B&K 2260, CEL 593, Nor 118, Nor 140 and Nor 121 real time analyzers are available. The B&K 2250 is becoming the meter of choice especially now the FFT and Tone Analysis options are available.
To measure outdoor noise and longer term surveys, we hire environmental noise measuring equipment, complete with Class 1 outdoor microphones and meter enclosures with rechargeable batteries.
To measure noise nuisance inside a complainants property we have both the B&K Matron II and Matron III systems as well as the Norsonic 121 Annoyance Recorder.
