Room acoustic treatment

I couldn’t find a thread specifically on this subject and triple glazing.

My room is 60% glass and my system Naim NSC22, Nap250, NPX300 and Linn Majik 140’s

I have problems with Sibilance on the treble with voice although instrumentation sounds lovely.
Most of the glass will be replaced with Laminated triple glazing at the end of the week, does anyone have any experience of this?
Will I need perfect fit blinds/Acoustic curtains?/Blackout blinds? I understand that too much treatment can have the effect of deadening the sound.
Any experts out there?

I have asked the question in another topic but thought I might get some more response by asking a specific question

Are you able to post a picture of the room?
Showing where the listening position is and the glass areas?

Getting a room to behave acoustically also involves compromising if it is not a dedicated listening room. My room opens into a dining area which makes the left and right walls to have unequal length. It is somewhat narrow. It is plaster and concrete and cinder block. It tends to hold on to bass while being somewhat bright. The windows are behind the speakers and we have a NYC skyline view, including the bridges.

For years we had wall hanging rugs, acoustic pillows, corner triangles and standing acoustic panels plus heavy drapes. Our living room looked like an understudy for StoneHenge. The heavy drapes darkened the room and compromised our view.

Finally my husband said NO. We got rid of all the acoustic treatments and drapes. Less became more. We chose speakers that worked in the room and did not compromise our view. We installed simple blinds and shades that were easy to use. Preserving the view became our priority. We accepted the room as is and worked within its limits. After a while things sounded great. Audio life became simple.

Will let you know - about to move from an apartment in an old convent with 3.1m high ceiling into a Penthouse apartment with floor to ceiling windows on 3 sides.
Had control of the room nodes with a couple of acoustic panels on various walls.

I use the app HouseCurve with a calibrated mic for the iPad, to measure, so you can have a benchmark before applying the room treatments.

Maybe some measurements are in order?

A search for triple glazing pulls up quite a few posts, maybe some of interest, e.g.

The white glass cabinet will be moved elsewhere in the house and the CD racks will go where the cabinet now stands. Logic says move everything to the other end of the room but behind the settee is a radiator and the electrics are behind the Hi-Fi.

Thanks, I did a search for accoustic treatments which didn’t draw out much, and the one on speakers is my own-thanks for looking and I am relieved to see one comment relative to triple glazing which seems positive.

A very interesting response and maybe I am overthinking all of this and as you say just settle for things as they are and get some speakers to match the accoustics of the room. The carpet was a helpful addition a few weeks ago. Did you use acoustic or blackout blinds? or just normal shades for the double glazing? I have perfect fit blinds (as in the pictures) and anticipate doing the same with the triple glazing as they let in resonable light even when down. I will know at the end of the week if the triple glazing makes a difference to the acoustics.

Hi, Thanks for posting these really clear pictures of your arrangement.

I am commenting on my assumption that the triple glazing replacement is only the glass to the exterior of the property?

I am not sure you have anything to be concerned about really. You have a vaulted ceiling which will help with spreading the low frequency room mode energy a little bit.

Personally, if I wanted to max the acoustic treatment I would target the first reflection from the side walls. To do this I would fit an attractive art panel absorber on the left wall where the cabinet is presently, and for the right wall glass area purchase a foldable screen panel absorber that self stands vertically that is folded closed and moved out of the way when not listening to HiFi.

Others on the forum may have other views, this is just my opinion, and in my own space I have a great deal of acoustic treatment.

Yes the new glazing will be the 4 fold opening being replaced with a pair of patio doors and glass panels either side. In 10 years I have not opened up the Bi-Folds due to inconvenience and weight, I fail to understand the trend towards opening rooms up to every insect and piece of dust floating around the garden…I know, I’m in a minority…LOL.
Thanks for your response and helpful suggestions.

Good plan!

I am all with you for what you are doing!

Whole heartedly agree with your observation re bifold doors.

I would suggest something like 3 floor standing acoustic panels in front of the window, 1 in front of the door, and one different attached to left wall.
It can be removed in 5 minutes when no listening.
What do you think?

Do you really listen with the speakers SOOOOO close one on the other ???

And why are there two sets of speakers crammed together in that tiny space? That alone can not be helping the sound.

This can also be caused by other reasons than room accoustics. I’d check the cables too and I would ensure power cables do not touch the other cables or run in parallel.

Are the stand mounts Wilson benesch? I’ve heared them with a 202/200 and they sounded fabulous.

Thanks for the suggestion, I’ll look into the cost, we have plenty of space so storage isn’t a problem.

Thanks for the reply my cables are a mess to be honest so something to think about and look into.
Yes the WB’s are on demo and currently I’m being won over by them. These are the first generation and WB are now on their 3rd Discovery. The linn’s have more bass but the WB’s have marginally more emotion in the voice and clarity. I’m about to try 3-4 other recommendations before making a final choice-the Linn’s will be traded in.
Thanks for responding.

No! the WB’s are on demo and are in the usual location of the Linn 140’s.

Sorry for not explaining.

Had a similar issue in my new room with a lot of windows directly behind listening chair. I used wooden shutters on the windows. This had a significantly positive impact. Still allows majority of light into the room. The shutters can be tilted wide open to completely closed. I keep them 3/4 closed and this has created a diffraction effect which greatly improved SQ without completely blocking out light with solid absorber panel. A good compromise for me. Your ceiling window is in a primary reflection point - try the shutters there as well.
