Meters to carry out Industrial Noise Assessments

To ensure employee's hearing is protected from excessive noise in the workplace. Excessive noise is noise that has the potential to damage their hearing. HSE states that at a minimum a Class 2 Sound Level Meter to BS EN ISO 61672-1:2003 or BS EN 60804:2001 should be used. Meters that do not meet these standards should not be used for Noise at Work measurements. Class 1 Sound Meters are a popular choice with safety professionals, as they give more accurate readings and are capable of other applications that require a higher grade.

  • Upper Action Level - LEP,d 85 dB(A) / Peak 137 dB(C)
    Employers must provide training and carry out risk assessments to employee's health where levels are at or above 80 dB
