Hi Jazz,

Thank you very much for the reply. I was on the right track for a change talking about the DB noise produced i.e. machine start up run down and like you say cutting! I have read on here that someone used polystyrene sheets on the walls. The trouble is say I have half a dozen machines I didn't want to box each in individually but more rely on the workshop to deaden the noise right down. I would like to be pretty sure about noise as we had a complaint about a radio not so long ago and it wasn't even that noisy! I have tried to look for case studies for use of machinery etc but nothing jumps out at me. I imagine noise is a problem that a lot of us have. I am thinking about buying some special foam and having a small scale test. http://www.ebay.co.uk/itm/12-x-Studi...item566cf2e634

Many thanks
