Different Types of Sound Level Meters

The majority of sound and noise level meters fall into one of three categories. These are Class 1, Class 2 and Sound Level Indicators. Class 1 and 2 Sound Meters are required to meet the full specifications of IEC 61672:2013, meaning they are suitable for performing measurements for Noise at Work

Class 1 Sound Level Meters

Class 2 Sound Level Meters

  • Compliant to IEC 61672:2013
  • Class 2 Sound Level Meters are the lowest class that can be used for Noise at Work Assessments
