Hazards caused by machinery noise

© WavebreakmediaMicro - Fotolia.com

The Machinery Directive requires machine manufacturers to reduce noise to the lowest possible level and to include information in the instruction handbook for the user of the machine concerning the residual risk caused by noise. Standardi-zation can support this directive requirement by standardizing technical meas-ures for noise reduction and test methods for noise measurement. There are shortcomings, e.g. in the use of, for example, "guide values" in specific machin-ery safety standards to describe the state of the art with regard to noise reduction
