We have an eagle in our machine room. Its makes so much noise that it is hard to work in this room. Does anybody know any cheap ways of shielding? -- Laura Creighton ihnp4!hoptoad!laura laura@lll-crg.arpa

Build in access doors so that you can change printer paper without completely removing the box. Build in clear plastic windows in spots where you want a viewing port. Cut openings for cables and printer paper to pass in and out. When your box is finished, you line it wherever possible with soft foam rubber of the type frequently used as packing material. Have you ever noticed echoes when you enter an empty room? The foam rubber soaks up sound the same way that drapes, carpeting and furniture deaden the echoes of an empty room. J. M. McGhee

You forgot one major step: install a cooling fan so that the expensive electronics inside (Eagles aren't dime-store items!) don't overheat. And then start all over again, because the $@#%@ fan is too noisy! Seriously, this is a real and major problem, and by far the biggest headache involved in noise shielding: providing adequate cooling. Fans are probably causing a major fraction of the noise in the first place! -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry

I'm a little confused by this discussion. Are you aware that printer housings, with built-in fans, noise shielding, and paper slots designed for the dimensions of most varieties of printers, are available from the usual sources of computer supplies, like Inmac, Global, etc.? True, most are overpriced, but it is certainly easier to just buy this sort of thing than to build it. (Assuming you don't work for the gov't, where the procurement paperwork will delay it for 18 months...) Maybe you are not on the mailing lists I am, but I seem to get hundreds of these kinds of catalogs, usually in multiple copies... Will

I posted the original request. My printer is fine. It is my *eagle* disk which is too noisy. -- Laura Creighton ihnp4!hoptoad!laura utzoo!hoptoad!laura sun!hoptoad!laura toad@lll-crg.arpa
