 The Generation 4 Noise Monitors utilise what is arguably the world’s finest acoustic ‘frontend’ from Brüel & Kjær. The Brüel & Kjær Type 2250 Hand-held Sound Level Analyser acquires over-all and frequency specific information. The 2250 is a precision integrating type 1 sound level meter which meets current international standards. Most importantly, this instrument can be easily removed for periodic traceable calibration. This capability provides very robust legal integrity to the noise measurements.
