Roof extractor fan noise control solutions
Our company has successfully solved many noise nuisance problems caused by roof extractor fans of both the centrifugal and axial type. On our fan noise reduction page, this picture shows the same roof extractor fan as in the photo above, but with the cowl removed. We have carried out many projects to reduce roof extractor fan noise, mostly using engineering solutions that were low cost to install. The disadvantage of completing so many sound suppression projects on roof extraction fans is that we often have to clamber up onto a roof. This is not a problem if there is a staircase, but not so easy where we have to carry sound measuring equipment up a vertical steel ladder to reach the roof!
