Hi, I need to make a cover wich can block most of the noise from a 1M long shaft inside some equipment wich has little else in it beside the shaft and some bearing blocks.
Idealy it would not be very heavy, easily fabricated and able to serve as a cover under its own strength. with unsuported areas of 200mm x 100mm.
Ive used sound deadening pads before, even resorting to some spare roofing felt on the inside of washing machine wich was pretty effective, but I havnt got a cover as such to atatch it to.
cardboard would be strong enough, but needs something rubbery to absorb the sound, can you get rubberised cardboard ?
rubber sheet would be good for sound deadening but wouldnt take a shape and keep it, not sure plastic would be any good at absorbing the sound.
best bet so far is to make a thin aluminium cover and atatch sound deadening pads to it, but I was wondering if there was anything better, although you can actually get aluminium sheet lamintaed to a layer of sound deadening wich is a bit expensive but might be worth it.
