Sound Muffling Projectors

Is there a safe way to sound muffle the projectors?? I am thinking of building say an MDF box to go around my chasis with enough room all round for cables etc. I am wondering if an enclosed box with ventilation holes drilled in it at the back where the projectors fan is will be sufficently air cooled too prevent meltdown. I saw one chap on the links page who was building a box to cut down the noise of his projector, made of perspex I believe.

Anyone tried this or no any links for more info.

Thanks

The >$5000k PJ forum at avs is your best bet for info on this.

IMO, just building a "hushbox" with an opening for the exhaust/inlet fan(s) would not be good enough, as quite a lot of heat is lost through the chassis/case of a PJ. Some "forced" airflow would be required.
 
Have to chime in here.......

For goodness sake don't go putting your projector into a box with holes for intake and outlet - it will cook in the neat little oven you will have built it !!!!!!! :eek: :eek: :eek:

AFAIK, hush boxes should be designed to have their own inlet and/or outlet fans, temp. controlled by the temperature in the hush box itself. They are often vented out of the projection room through trunking/whatever.

I have no doubt that designing and making one is well within the capability of a competent diy'er, but do all the research you can - the > $5000 projector forum amd the Home Theater Builder Forum on avsforum.com is an excellent starting point. Sign up there and post your question - there are thousands of members signed on every day and they are just as willing to help as members here are - some of them just have more experience on average than we do. Mind you, I think their forum is excessively moderated - nothing as good fun as we have here ;) , eh, Kramer:D .

Good luck,

Nexus, think yourself lucky...I dream of 28db...currently got about 40dB :eek:

I recently tried replacing a couple of the fans but found when I replaced a 36dB with a 28db rated fan, the 28 was actually louder when fitted :(

So I'm interested in doing something like this too don't see that it'd be too difficult to build a box and put in a couple of silent 80mm PC case fans for extra ventilation (tho the extra PSU might be a pain in the arse!).
 
Goof,
