Acoustic Treatment: Treating a room with Windows and Doors

[@3D1ofakind]

I just use a rug as curtains with 2500 gsm, works extremely well. Keep in mind my window is behind my speakers. I get surprisingly neutral bass with rear ported speakers since it travels straight through the window avoiding the need for bass traps. then the rug cleans up any mids and highs that cannot travel through glass coming from the rear port as well

Those guitar hangers at 1:41 are very interesting.

What you mean by, should we put set in front of window or not?

[@michaelandrewgarcia96]

Would using a blackout curtain on the window help at all?

[@GIKAcousticsLLC]

Thanks for the question. While blackout curtains certainly can help with ultra high frequency absorption, they are no substitute for proper acoustic treatment. Typically curtains are under an inch thick, making them ineffective as broadband absorbers.

Curtains can help immensely, but they won't tell you that it's a "real" acoustic treatment because they don't sell them. A lot of blackout curtains are also rated for sound dampening and can absolutely be a solution, especially when you double them up and mount them as close as possible to the glass. None of this is magic nor does it have to cost your life savings, just use some ingenuity and your ears.

Two of my walls behind the speakers (diagonal setup) are just widows with heavy curtains. With curtains closed the room sounds great. In fact I think the vibrating windows are behaving like a diaphragmatic material and cancelling my bass. The curtains are treating a bit of the highs. All I need now is more high and mid treatment.

just use a rug as curtains. 2000+ GSM will get frequencies down to 150hz thereabouts

what BOUT THE floor?

[@GIKAcousticsLLC]

Great question! We have a video on the subject and the impact of floors in acoustics - and what you should be aware of when looking to acoustically treat your space, and the impact of hardwood or carpet. kzbin.info/www/bejne/Y4Woe6WFqLN6la8

@@GIKAcousticsLLC yeah the floor u need to build it .cant use panels heheh

[@GIKAcousticsLLC]

100% True, but you can mitigate floor to wall corners with laying bass traps straddling the corners, and treating the ceiling is a better option than the floor since it is usually around a similar sized area yet you don't typically need to make room to walk on it!

@@GIKAcousticsLLC will 70 hz modes go away with just ceilling treatment? usually they happen exactly at the listening position....and if u only treat the celling the first reflections from the floor will hit ur ears man...

The thickest curtain is always the choice for windows 🪟

[@lllllllllllllllllllll1lll1]

Absolutely- to add: seal windows with acoustic caulk or similar flexible caulk, replace weatherstripping with whatever will seal tightest while still conforming. Cheap automotive tint film (or fancy acoustic film) will reduce panel resonance while retaining visual clarity. Air seal should be #1 on the list. Then loose, heavy curtains. The first should be "sealed" to the wall to provide a proper buffered air gap. Velcro on the edges works well. Then the second should be as heavy as possible, with an extra 2-3 inches of fabric draped on the floor. The looser and more folded, better the absorption+diffusion.
