How can I eliminate some echo in my living room?

I recently moved into my new house, and this sucker has some high ceilings in the living room coming in at 20-feet at one angle. I can hear an echo when I lightly holler in the house, and I am finding that to be the case with my audio as well. As you can see, not only are the ceilings high but it is completely wide and open to the kitchen, dining area, and the huge hallway. I still have to hang some art on the walls, but that will mostly be in the hallway. In the area where the TV is there is this odd area, or lip, which has opportunity to work with. With the speakers facing out from that, I am not sure if that is even worth it? Could audio travel up there and hang out?

Anyway, what do you think would help this out? Acoustic panels or some really large art up on the high wall? Foam in the corners? Dedicated acoustic panels (see link below for some I found). I welcome any ideas and/or links to products which may help this situation, and I thank you all!

What am I using?
Yamaha RX-685
LG C9
Andrew Jones Pioneer Speakers (I do have the atmos modules on top of the front towers)
Hsu VTF-2 Mk5 subwoofer

Nothing? Did I post in the wrong thread perhaps?

I think it's assumed you must thoroughly scower the acoustical treatments thread here before asking that type of question. My new living room is also echoey and I'll be looking at bookshelves, wall decorations and thicker dampening curtains to reduce it. Home Theater environments require different types of dampening which by the pics, you do not have to worry about.

Thanks! I checked them out, and they certainly have some cool options. I already have SO much artwork of my own, which gives me the opportunity to put foam behind the canvas, which I did not think about before. Do you think some regular or eggcrate style 1" foam behind every canvas would help a little?

Probably not. I'd put white ( if you plan on keeping the walls white ) acoustic panels in various places.

Others may chime in, but I think the canvas needs to be acoustically transparent or the sound will reflect off of it and not be absorbed by the material underneath. I believe they have the ability to put any image on their canvas so you might could get the same picture, but it just wouldn't be the original.

As for the foam (and yes, you can certainly make your own), most use Owen Corning 703 foam that comes in 1", 2", and 4" varieties. OC703's specific use is for acoustic panels so it's purpose built for that use. You can also use Rockwool insulation. The thicker the panel the lower the frequency it will absorb.

Thanks for chiming in again. Good point about the canvas. I suppose most artist canvas, especially with paint, is already a little solid as far as the surface area. I will have to do some digging around to see if foam behind it would help at all. Surely someone out there has done some test to determine this, but I do think you are probably right.

I will check out that foam. I found these as well. http://www.usafoam.com/acousticfoam/acousticfoam.html

I do have an opportunity to use something as I am going to create a project similar to this which will be about 68" by 68". It will be more porous than canvas perhaps. I could easily stuff some foam behind this.

I have decided I am going to build my own panels such as in the last link I posted. If I use a porous cotton colored fabric from Hobby Lobby, with a furring strip frame, and the insulation in the middle......do you think that would help the echo? I would build about 15 of them in 20x20 squares and place them in that large area on the wall up top. The speakers are much lower at ground level of course and would not directly hit these panels. However, would it potentially solve for the echo? Is there a certain thickness of material I need to use?

My guess is it will help some but I’d use OC703, Linacoutic Duct Liner, or even acoustic drop ceiling tile. Acousimac sells DIY kits with everything you need to build panels in lots of different shapes and I think will also give some advice on where to hang them in your room.

They got back to me, and def said I needed more than the room can handle, which of course I expected that response.

Check out the link below. Is this decent foam to use as well or is it not advised compared to the others you mentioned? I wondered if the pyramid shape does anything "special".

It looks like it takes 4" of foam to provide similar results to 1" of Owens Corning 703.

At least they pubish the data so you know what you're getting.

Math doesn't lie, usually. Thank you for pointing this out. The 1" is def the way to go with this in mind. Now to decide whether to DIY it or just buy some and pay double (or more) the price.

I've never used it, but the Eco-Core material from Acoustimac looks even better than OC703. Specs for 1" attached.
