Acoustic Blanket for TV

I put in a 50 inch TV near the left speaker in my office. The TV is against the side wall and the speakers are in the front wall. I am getting some reflections as I expected.

I was hoping to talk with these guys about getting some fabric to control the reflections.

However, I am tired of being sent to voicemail. I think it is time for another approach.

I have also contacted GIK Acoustics about this TV issue because I was at one time thinking about putting the TV in-between the speakers. They have not gotten back to me yet. However, I came to my senses on that and decided to move the TV to the side and not in-between the speakers. I was hoping to use a 40’ TV but that one is on it’s last legs so I had to use the bigger 50" TV.

I talked to a company about sound absorption blankets but they told me that their blankets would be too heavy for a TV.

What have people used to cover their TV’s to make nice with the acoustics? I am trying a folded quilt now and it works OK. However, my wife will eventually notice the missing quilt from the guest bedroom. So I wanted to get some suggestions before I spend some money on this problem.

The guy at Acoustic Curtains got back to me today. 
https://www.acoustic-curtains.com/curtains/acoustic-curtains/

Our custom made sound absorbing curtains are pleated with 2x fullness using fabric Destiny, Nova Suede or Visa Velvet. Hooks are installed on the back side and the curtain comes ready to hang.

These fabrics and curtain construction were tested at independent acoustical labs and are rated at .65 NRC (this means 65% of the sound that comes in contact with the curtain will be absorbed in the fabric and curtain folds and not reflected back into the room, significantly reducing echo and reverb.

Your Quiet Curtain, 48” wide x 30” high, unlined, costs $275.00.

The panel I got seems like the better solution for the TV. However, I have 2 windows that may benefit from these curtains.

Another option this time from GIK Acoustics that was recommended to me by the guy who did my GIK panels.

If the problem is only the TV I have had success with using Alphas as they diffuse and absorb. The thicker the better.


One of these:


6A Alpha Series Rectangle with 2D Scattering @ $198.00

4A Alpha Series Bass Trap Diffusor/Absorber (Rectangle) with 2D Scattering @ $138.00

An Update:

I received the https://www.acoustimac.com/ panel that was previously mentioned. I am impressed at the ability of this panel to absorb the sound and make the TV doable in-between the speakers. I also have the moving blanket over the TV and then the panel resting against the blanket. So a double shot of solutions.

However, there is still a bit of hardness on the sound that was not there before the TV went in-between the speakers. I think I said I was going to keep the TV to the side of where I sit. It looks like that is what I will do. I wanted to see if the in-between the speakers setup would work.

Prior to trying the blanket and the panel the sound was awful with the TV in the middle. With these 2 I feel it has improved about 90% but that is not good enough.

The reflections off that TV are not much different than the reflections off a solid wall maybe just 0.2 ms earlier. Your first impression was right. Put the TV between the speakers and re program your filters. They will handle any change made by the TV. Where you have it now is right smack in the way of the most important 1st early reflection. Move it and there will be no need to cover it with anything.
