Noise abatement

Noise can be reduced in a number of ways. The German Noise and Vibrations Occupational Safety and Health Ordinance (LärmVibrationsArbSchV) requires noise to be prevented at the sound source. Technical measures take priority over organizational measures; these in turn take priority over the provision of personal protective equipment against noise (hearing protectors). The TOP principle therefore applies: technical before organizational before personal measures.

The sections below describe various technical options for noise abatement measures. The purchase of low-noise machines and the practical example of low-noise saw blades constitute technical measures for the reduction of noise at source. Noise diminishing through room acoustic measures is also a technical measure, but is achieved by measures on the sound transmission path.

The purchasing of low-noise machines
The IFA has compiled the information needed in order to support companies seeking to purchase noise-emitting machines or replace existing machines with quieter products. The information is divided into the following topics: Legal provisions ...

Noise abatement by room acoustic measures
Noise exposure in workspaces consists of sound emitted directly from machinery and equipment and that reflected by walls and ceilings. Ceiling and/or wall surfaces designed to absorb sound, reduce the reflected sound component, resulting in a ...

The circular saw as a noise source: Simple solutions for noise reduction at the workplace
Risks of hearing damage presented by circular saws The high noise emissions are a major source of noise exposure for workers working on circular saws and at neighbouring workplaces. Circular saws are used at many workplaces in wood processing ...
