Thanks again Greg, One final question I would just like to ask for my project planning. Should I consider active noise control as an option. In principle I know what needs to be done, but in practice active noise control seems to be not so easy. I am working with noise from a duct so much more...- kirkkse

Problem is a noisy "leaf blower" fan...- kirkkse
