Class 1 & Type 1 Sound Level Meters for Occupational Noise & Environmental Noise

What is a Class 1 Sound Level Meter?

A Class 1 Sound Level Meter will be designed to meet the requirements of IEC 61672-1:2002 (or the equivalent BS EN 61672-1:2003) standard and will meet the performance requirements that are in this standard for a Class 1 instrument.

The older sound level meter standards IEC 60651 and IEC 60804 used Type rather than Class but these standards have been superseded by IEC 61672-1:2002. A Type 1 sound level meter would be roughly comparable to a Class 1 instrument but it would not be able to fully meet the lastest standards.

The ANSI standards S1.4 and S1.43 use Type rather than Class and these are equivalent to the IEC 60651 and IEC 60804 standards.

Typically, Class 1 Sound Level Meters are suitable for environmental noise measurements but can also be used for occupational noise measurements such as the UK Controls of Noise at Work Regulations or the OSHA Occupational Noise standards.

You can read posts on our Blog about the differences between Class and Type in sound level meter standards as well as other posts about standards and noise measurement instruments.
