Applications
- Evaluation of occupational noise according to CFR 1910.95 (USA), ISO9612:2009, L108
- Hearing protection selection
- Noise exposure calculation
- Ensures compliance with the occupational noise standards and regulations
The CEL-dBadge2 dosimeters measure and store all relevant occupational noise parameters. For hearing protection selection the dosimeters simultaneously measure LCeq and LAeq. The SNR and HML
values are specified by manufacturers. LCeq and/oder LAeq may be combined with these values to determine the sound pressure level at the ear using simple, internationally recognised calculations.
The CEL-dBadge2 PLUS and dBadge2 PRO models additionally offer an audio recording function on exceedance of a pre-set sound level and the recording of an audio note before a measurement is started. Furthermore the dBadge2 PRO model allows octave analysis. The Airwave App permits to start, stop or pause a measurement and to monitor the battery state, measurement time, storage capacity and alarms.
The dosimeters are available with complete accessories, including sound calibrator, carrying case, wind screen, user manual and charging station.
