Wind power without the annoying hum
Wind farms are not popular with everyone. Residents are often disturbed by the humming noises they make. However, this problem can be mitigated.
The movement of wind turbines causes strong vibrations that can be perceived as unpleasant noise. This disturbs local residents and is often a central argument used by opponents of new wind power projects. While the noise cannot be prevented entirely, it can be massively reduced by devices known as tuned mass dampers. Phoenix Mecano supplies key components used in these dampers.
All mechanical applications generate noise. In car engines, a water or oil jacket is used to dampen this noise. This is not possible with a wind turbine, which is why tuned mass dampers are used. Mechanical noise is defined as vibrations. Electronic components can generate countervibrations to neutralise these and make them inaudible. A crucial component required for this is a coil with an iron core tailored to fit the object.
Tuned mass dampers can reduce the noise from wind turbines to such an extent that it is no longer a nuisance. This is a great relief for people living nearby and takes the wind out of the sails of a central argument against the construction of new turbines. What’s more, this can stop the turbine from having to be operated at reduced power in order to comply with noise limits.
