I have a Mits DLP TV. It sits in custom built entertainment center. It is enclosed on all sides except of course the front. The fan noise seems to bounce off the sides and back into the room. It also penetrates the back wall into the room behind it which happens to be the master bedroom. It bothers my wife to the point that if she goes to bed early I have to turn off the TV. Would lining the walls of the TV enclosure with some kind of sound absorbing material help? If so what would be the best material to use?

Johns Manville 814 (2") or Owens Corning 703 (2") might help. They come in 2' x 4' sheets and are yellow. You would need to wrap some cheap thin fabric around them if they are visible form the front. 2" thick cotton panels are great as well (see link at bottom of post).

You will need to contact your local HVAC supplier for this type of material. They are not available at HD or Lowes. If you can't get them locally, contact fellow AVSer bpape. He sells the material.

You could also look at buying some of the sound absorbing foam. We used it in a computer room by a portable A/C unit. It cut the noise level down about 50%. I cannot remember where we bought it, sorry. However, check out THIS (http://www.soundprooffoam.com/acoustic.html?page_type=Sound%20Absorption) place.

Good luck,

Bpape has the stuff, though if the sound is going through the wall, I'n not thinking lining the cabinet will do much.

If you are up for an adventure you might try to modify the TV with a quieter fan. On a related note a dozen years ago we bought a very big cabinet to hold a CRT TV. When I put the TV in there it sounded like crap. I got some fiberglass ceiling panels, wrapped them in black velvet and friction fit them inside the cabinet. There was a dramatic improvement in the sound quality. The 1 inch sound absorbing panels we now use for acoustic treatments might be of benefit.

The fan noise is bothering her? When is a fan louder than the TV itself. I suspect the audio from the TV would bother her more. Maybe her going to bed early and asking you to turn off the TV is her attempt to send you a different message.

I have a Mits DLP TV.

I just bought A 65" Mits DLP and can't hear the fan AT ALL, standing right next to it. If it's new, I would have it checked under warranty. BTW that thing weighs less than my 32" HD CRT by about 20 pounds!

good advice indeed

good advice indeed

If only Yoda were here to nod sagely and say, "A different message, she sends you, indeed!"

A TV fan whose noise pierces through walls...or does she maybe have mutant powers of insanely acute hearing?

Is it possible that the entertainment center you have it shoehorned into is choking off all airflow to the TV set causing the TV fan to ramp up to overdrive in an effort to keep the TV cool?

Is the TV just as loud when you first turn it on after being off for a couple hours (still cool) as it is after a couple minutes of being on (starting to heat up)?

For your wife’s sake, you really should let that "puppy" get some fresh air… and it would probably be a good idea to ventilate the TV too so it doesn’t suffer damage… ;)

I appreciate the marriage advice but it isn't necessary. My wife and I are both retired. However she still works two days a week and on the nights before she goes to work she goes to bed early so she can get up at 4:30AM. She also babysits for one of our daughters one day a week and goes to bed early the night before. And it's not the TV audio that bothers her as I use wireless headphones after she goes to bed. So all kidding aside this was a serious question.

The TV enclosure has plenty of room for good air circulation and the fan noise is just as loud when you first turn on the TV as it is after a few hours of use. The fan noise is audible during quiet scenes in TV shows and movies but not loud enough that I find it distracting.

I've seen some acoustic panels on the internet but they are very expensive. So before I spend the big bucks I would like to know if they would help reduce the fan noise being reflected out of the cabinet?

As for my wife's sleeping I bought a new LCD HD TV to replace the old CRT TV we had in the room our grandkids play in when they come over. I also got a new HD DVR to replace the old DVR in that room. So now instead of just recording kiddy shows on that DVR I now record kiddy shows plus shows I like to watch that my wife doesn't. So that part of the problem has been solved.

Acoustic sound panels do indeed reduce reflected sound. Not 100% though. You can buy raw sound absorbing panels (fiberglass) at sensiblesoundsolutions.com and wrap in your fabric of choice. My back panels were in a black stretch velvet.
