Acoustic Room Treatment

You disconnected all that stuff in the time it takes to drink two beers?
You-da-man!

Dick, I've said this before - very nice looking system and nice looking home.

As I look to the sides and behind your speakers, you have a lot of hard, reflective surfaces and I'm willing to bet that a lot of bass and lower midrange energy gets amplified in the corners and comes bouncing out of there. As much as you like your system now, room reflections, especially from the corners are possibly causing some serious mucking up of resolution and imaging.

I think you really need some corner absorption, and those little triangular pillows that you stick in the corners of the ceiling are really effective.

If there was a whorehouse orange, it might match my chairs somewhat...last time I looked at curtains my landlady took me to a shop and was somewhat aghast at my choice in color, although it wasn't of the whorehouse variety. A lot of the curtains over here come with a sunblocking, or probably more of a heat blocking layer behind the actual curtain, so maybe that will work better. Guess I should get off my ass and see

I agree on the legos unless I glue them. Maybe that is what was intended and my German just wasn't up to the task when reading the installation instructions...

Max, I chew tobacco, so one of those is for other purposes, but I believe it took three Strongbow ciders to get the job done

, not to mention a couple more for testing purposes. I don't like to move the stuff too much with a buzz. Amps are 110 lbs. each and the speaker 17? lbs. The preamp and CD player aren't exactly light either, with or without the separate power supplies.

That's not counting releveling the rack that holds the turntable and the turntable, which I haven't done yet.

cheers,

Dick

Would you settle for PIMP orange?

geez, at least take the time to resize the photo!

Just kidding, without the crushed velvet look, maybe, but with a little more brown in it.

Jerry, thanks, and I know, it's just a matter of getting the stuff over here. I went to the local audio shop today and asked about room treatments and got an incredulous stare and it wasn't a Greek/English translation problem.

Didn't surprise me since they didn't have interconnects readily available, even cheapos when I asked a few months ago, but I thought I'd try.

cheers,

Dick

edit...PS, did you lose weight?

Hey Marbles, was the photo taken before or after the sofa session?

I mean, if after, you DA MAN, dog!

You still standing.

From the college days, of course.

Judging from my eyes, I'd have to say AFTER!

Dawg, naw not skinnier, it's just those 8" platform shoes make me look TALLER

Good acoustic isolation, though.

Back to isolation...being lazy, I'm thinking about various ways to cocoon my room in acoustic foam and the easiest way so far is to sew it together with fishing line or something similar and hang it from the ceiling. This will let it be removable somewhat and shouldn't damage the walls. Is this a no-no? I found a place that sells plywood, but over here they come in 6xvarious sizes and might not make it up my stairwell very easily.

cheers,

Dick

Dick, there's really no such thing as a no-no. I mean, everything we say here is relative, we can talk only about general effects, but what they will be like in any room remains to be seen, due to many variables any room will present on its own.

Things that work well in one place may hardly work at all elsewhere. Also, it's no just what you do, but how you do it, and to what extent. I'm afraid personal experimenting is the only real and true way to find out. But then, that's the fun of it.

Cheers,

Hi Dick;
You really don't have to do the whole room. Just the back wall and up the sides about 3 to 4 feet.

Hi,

This is a great thread!!

My new apartment is a sound nightmare. Rectangle living room opening to dining room/kitchen. 9 foot uncoated/untreated ceilings. Floors are wall to wall carpet. One side wall is a sliding glass door to a balcony. It has drapes tha I close while listening to the system. The other side wall is across the apartment because of the open dining room area. The room resonances are horrible!!

I am going to order some of the parts express acoustic foam to treat the wall behind the speakers. I'm wondering if the 1 1/2 inch thick foam (part # 260-316B) would do as well as the 2 1/2 thick foam Dan mentioned. It's the same foam but thinner... It's also about half price

Would it be sufficient for my application??

Are the drapes sufficient for the sidewall reflections?? Do I need to treat the far dining room sidewall too??

Also, does anyone know of a good place to find a cheap solution for corner traps?? DIY isn't possible for me at this time.

Your help is appreciated

It sounds like you have limited wall space to hang any treatments. I would but as much as you can on the back wall. Drapes are better than nothing on the glass. Assuming you don't want to change the drapes to a very heavy multi-layer drape, you can maybe use something to hang in the midpoint area (first reflection) of the drapes for temporary treatment.

Check out eighth nerve's circle and site here. They have some pretty interesting stuff.

The of course there is near field listening and head phones

this seems to say if your room sucks, try these..

I have never heard these and don't know if they suck, or if they work.

What do you guys think?

nathanm · « **Reply #74 on:** 14 Feb 2003, 11:10 pm »

Well, if the chairs come with those girls I hope they suck...

I once scoured Wal-Mart for some manner of horn thingy to try putting over speakers, but the closest I could find was a glass vase. Hmph. Looks like it's just making your sweet spot much smaller and the speakers more directional. Hmmm. The best part about that 2nd webpage is the semi-broken English. That stuff cracks me up everytime.

Thanks for the sugggestions

I'm looking into some of the Eight Nerve stuff and some foam for the back wall.

The standups from Eigth should help fill in the open spaces

Thanks again!!

the best place to get advice for room treatment is at acoustic science corp. Art Noxon the pres has made available free of charge to everyone who submits photos and plans of their room plans to treat your room. I have done this and my room now is better than I could ever imagine

I just finished installing the remainder of the sound traps but here is my room before all were installed

MaxCast, Xi-trum, how's it going, any results?

I'm coming to the conclusion that Dan Banquer is absolutely right about the need for acoustic treatment. I think I'm starting to tell the difference between the sound of a system in an acoustically treated room and one that is not. It's not just obvious things like slap-echo. Removing the reflections really does reveal details and improves the presentation. I don't care about imaging per se, to my mind it's sort of a party trick that is somewhat secondary to the real goal of creating an audio illusion. (Some etymologist around here will probably have a field day with that one

) But that improves too.

I'd go as far as so say that if you have say $5k in gear and no acoustic treatment, then you may as well stop spending money.

And... you pimp daddy wannabees want to invest in some purple foam to go along with the orange sofa...

oneobgyn, your link above doesn't work

Got another?
