Two-in-one instrument
October 1st 2005

In addition to the new limits for occupational noise, many safety officers are now having to deal with environmental noise issues, increasing the need for a dual-purpose measurement tool that can cope with any measurement situation.

The CR:821B sound level meter from Cirrus Research has been designed to meet these requirements. It will provide for the measurement of Leq and LCpeak for compliance with the Noise at Work Regulations, with Deaf Defier3 software providing for the calculation of noise exposures and LEP,d.

Octave bands can be measured and the software will help in the selection of any appropriate PPE using the built-in database of more than 85 hearing defenders and earplugs.

The sound level meter will also measure Leq, Lmax, L10 and L90 for recording environmental noise levels and, when used with an outdoor measurement kit, noise levels can be measured and automatically logged for up to 14 days in any weather condition.
