Acoustic treatment for side glass doors / please, need ideas.

Very easy and not expensive either. Buy white or room darkrening pleated shades. You can pull them up and down like blinds and they certainly soften the acoustics of a hard glass door. They look nice too. 

In addition to shades please consider adding something to damp the glass. The Marigo 40mm VTS Tuning dots are ideal for this purpose

If for for some reason you decide against drapes I have also had very good results addressing room acoustics with a lot of glass using the Synergistic Research ART system (the resonating bowls). This gets pretty expensive fast but it works well and looks very nice

if you check out my room (similar size to yours) you will see both of these methods applied to a large window (plus I also hung ASC panels on it as well)

Thanks folkfreak for your ideas, in other situation I can consider them but I need to make the room nice also so I think I need to go with the shades.
roxy54, sorry about my english but when you mention pleated shades you mean the ones that have a design that looks like a v regular and then inverted right?, basically no flat. What about thickness? material? any link of something that you recommend? thanks again both for the input.

Pleated shades or a roller blind will have little to no effect as they are in practice acoustically transparent. It may ameliorate some of the excess HF but that’s about it. If you really want an acoustic impact you will need heavy lined drapes. I’m sure your significant other won’t mind the tuning dots so do think about them, they may foul the action of a sliding door however as they are quite thick

One other thought is to do as I did and use the ASC sound planks or GIK panels others suggest

I have them attached via velcro (hook/eye) tape. You can leave the velcro on the glass but only attach the planks when you are listening seriously. Again it’s going to end up costing you but this would work and be flexible

You're not worried about the glass glass which you use for your Scotch? It's a primary reflection point since it's in that sweetest sweet spot. 

Best place to start would be something like a Mapleshade brass or maple scotch tumbler.

On a serious note, I'm dealing with a similar issue. The far wall is mainly glass windows, and the designer just doesn't get it. I'll be using a 15-inch woofer as shield for the Tuesday battle, err meeting. Their recommendation is to do nothing...to let the beautiful light in. Since it is three against one, maybe 2 and a half since one of the designers is moderately sympathetic to the whole audio thing...anyways, you know where this one is going.

Curious to see what is recommended. I'm considering GIK free standing panels that can be moved out of the way easily. Though I'm sure I'll need to get designer sign off on the fabric color.

You might want to look at groffkait's website, he sells very small adhesive copper strips, that tune the glass, highly effective & inexpensive, work well with pretty window treatments.

Don't do anything until you've setup your system in the new room.  It reads as if you're speculating about a potential problem.  Wait until you find out if it's a real problem.

"You might want to look at groffkait’s website, he sells very small adhesive copper strips, that tune the glass, highly effective & inexpensive, work well with pretty window treatments."

The 1" copper Flying Saucers for windows (1 per window) and sliding glass doors are not dampers or tuning devices. Flying Saucers for Unused Wall Outlets which are copper on plastic inserts are their companion product. Both products should be placed in ALL rooms of the house.

Thanks to everyone who post here helping me to find the best option. Definitely I will go with drapes because looks like blind shades will not do the job correctly if they are not thick enough. Just found this:

Maybe this would be the solution, what do you think?

:

Those curtains look nice -- good to see they have testing and data to back up the "soundproof" claim.

Tell us how and why the flying saucers for windows work. Tom

Tom, I'd like to help you out. I really would. But if I told you I'd have to kill you.

I already know why...Tom

I’m positive you don’t, Tom.

Ummmm...blackout drapes. You can even buy the material and have them custom made. You can work out a suitable method for temporarily hanging them and removing them like velcro, etc. I'm sure we're similar in that my wife controls the decor (she has great taste), with my final cut, except for the A/V wall and my office/listening room where I have all my mounted heads (just kidding). If she can find a heavy enough material she likes she might let you install them permanently. Or you can impress upon her you haven't asked for much in the remodel so she could make this concession. Good luck. Having owned a Custom High End install/dealer business (just for info, not bragging-if you can get someone to pay you for something and is happy about it...) I have used drapes like these and some I have on a drop down roller used for movie screens that is also triggered by the HT remote to auto drop for movie time. Lots of good options, but heavy drapes are great. A little more A/V dampening never hurt anybody.

Sloryder, thanks that's a good idea, I'm sure my wife and I can get an agreement on that. 

Blackout drapes are good ideas.  Used them myself. Work really well.

I also want to suggest, that while imperfect, treating what you can can make up for what you can't. For instance, extra thick rugs, ceiling treatment, and diffusors between the speakers may not fix the glass, but they can make things so much better.

Best,

E

Thanks Erik, I think I have a good idea about what to do with side walls.
Back wall will be fully covered with a LPs rack, right to letf floor to ceiling. About front wall,  any experiences with bass tube traps in the corners?

Bass traps are great, also suggest considering diffusion, especially behind and between the speakers.

Contact GIK acoustics for pro level help, and very cost effective products.

Best,

E

Also, you can experiment a little with pillows and blankets. Try throwing them around on the floor, between and behind the speakers. :)


Best,

E

Thanks for your responses. Will do some research about diffusion, but in the middle of front wall will be a TV so there is not much that can be done there.

I knew it! 😀

Try setting up you system for near field listening

Great recommendation!    +1 @brf 

brf, what do I have to take into consideration for nearfield listening?. Thanks

...a hammer...

I know, not practical...;)  Lots of better above, and the nearfield approach can work if your space and the other accouterments will allow it.  Tends to a low SAF, since your space is small....but since her 'embellishments' have backed you into a corner, you hopefully will get slack in the 'decorative scheme' of things...

Be sure that I will decide whatever I want and be the king .... of my small space ...

brf, what do I have to take into consideration for nearfield listening?. Thank

If you Google "Near Field Listening" it will give you more information than I can explain in this thread.  Good luck!

ok, thanks

Ah, well good... *S*  Small can be beautiful, and kingdoms don't necessarily need to be vast.  Good luck with yours. ;)  And happy listening...

I would be remiss if I didn’t put a plug in for crystals, which can be quite effective in dealing with vibration of glass doors and windows. 

Thnaks asvjerry is better for me to see the things like that .... 

Check out the Acoustimac website.  I believe I saw several products that might work for you.
Are  these glass sliders or doors?  Where in the room are they relative to your speakers/listening position? 

They are doors and run almost all the long walls. Basically I have 3 ft of wall then 9 ft of glass doors, and again other 3 ft of wall.  Front and back walls are regular, no glass. This is the same for both long walls.
Relative to speakers the glass doors starts about 1ft after the speakers (speakers are about 2ft from the front wall and 1ft from the sides).
Hope I explain it correctly for you to understand.

Listening position is about 8 ft from the speakers so basically I have the end of the doors by my side.

Is going to be very difficult to cover the sides with pannels because aesthetics so I think this would be the only real option:

Have you thought about GIK's art panels?

Impossible over the glass doors ...

Not on the doors, but anywhere else. :)

Again, I really like black out courtains. When shopping, a neat trick is to put your ear next to the curtain. Not ON it, but next to it, you'll get a good idea of how absorbent they are.

Also, remember, deficits in some areas can be made up for (imperfectly but well) in others.

Best,

Erik

Understood, thanks for the tip Erik

can you listen with the doors open?

do this in steps:

Phase 1 - heavy curtains over the closed doors

Phase 2 - get & read the Master Handbook of Acoustics; do the calculations for high vs. md vs. low freq. regions for your room
- then do further tmts

Mathematics to the rescue! Hurray! 😬

In my listening room I have 8' sliding door on left side, 3' x 6' window directly behind equipment and 4' x 6'8" doors on right. My first approach was the Marigo Window treatment on all. That took a noticeable bite out of the muddiness/bounce I was hearing.  I then put vertical fabric blinds on the doors and fabric venetian blinds on the windows behind the gear which helped dampen the LFs and lessen the glass bounce. The real improvement however came with finally adding ASC Thermal tube traps in each corner. The traps cleaned up remaining ugly acoustics in the room - not just those caused by the amount of glass. Plus by rotating them (top & bottom) independently, I can fine tune them to the music I'm playing (e.g. digital v analog).  I took it step by step assessing each one along the way.  That's my experience, FWIW.  Good luck   

Thanks for your comments but honestly can't understand how tube traps can deal with the first reflections from both sides, would you please elaborate? 

Jorsan,

I think  papafrog is being a little imprecise, but he's not overall wrong. Personally I like GIK acoustics soffit traps for cost/value.

We focus a lot on direct reflections, but reducing the resonance time across the frequency bands can be an amazing improvement.

Best,

E

Understood, thanks

looks like the soffit traps are for bass, if I'm right, they will not deal with side reflections of trevel / midrange sounds right?
