This year, DIN EN 61672-2 (Pattern Approval Tests of Sound Level Meters) will be issued. At PTB, a new automated measuring set-up has been developed by which it is already possible to test sound level meters acoustically according to this new standard. Within the scope of these acoustic tests, the frequency weighting and the directional characteristic of sound level meters are determined in the anechoic room. Verification of frequency weighting takes place in the frequency range between 25 Hz and 20 kHz. The directional characteristic of a sound level meter is measured in the angular range ± 150° and at frequencies between 500 Hz and 12.5 kHz. With this new measuring setup, PTB possesses a unique automated measuring setup for the acoustic testing of sound level meters and microphones in the anechoic room which enables testing according to the DIN EN 60651:1994+A1 and DIN EN 61672-2 standards and meets highest metrological requirements.
