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 1 offers greater accuracy which is especially important for any legal proceedings
  • A Class 1 Sound Level Meter is required for Environmental Noise Assessments

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
  • Generally come with analysis software

Sound Level Indicators

  • Generally low cost, suitable for spot checks and general noise level indication
  • Indicators typically don't measure Leq, which is measurement parameter that's necessary for performing measurements for multiple applications.
