Abstract
Noise in the workplace is a serious health hazard in many occupational fields. This results in reduced concentration performance or increased nervousness, but can also lead to irreversible damage to the inner ear. It is therefore important to keep noise and disturbing background sounds at workplaces to a minimum. The Institute of Measurement and Automatic Control at Leibniz Universität Hannover is researching active systems that are capable of attenuating noise by means of additional compensating loudspeakers. As such systems always have local, spatially limited zones of action (so-called quiet zones) due to physical conditions, their use on individuals results in numerous difficulties. Besides the development of sound control systems, the research focus is therefore on the visual detection of the person in whose environment the noise is to be attenuated, as well as the implementation of a suitable reaction to detected movements. In combination, this can guarantee an interruption-free and motion-independent noise reduction. For the experimental validation of the developed system, a new type of test rig was constructed, which proved its effectiveness when used on humans.
