im concerned about noise. does anyone with hands on experience of using these have suggestions?
what id usually do is use 5 metres of acoustic ducting either side and the fan unit placed in a box what is muffled with lots of rubbery carpet underlay. i was curious what people have used what they can say killed the noise low enough to not be heard outside the room it was in?
