Best way to “soundproof” wall of glass
Okay so I’m very aware that “soundproofing” is a broad term - what I guess I am really looking for is the best way to sound insulate/stop sound transferring OUT of my space?
I have just signed the lease on a small commercial space that is in the ground floor of an apartment building to run my singing lesson business out of.
My biggest issue re: “soundproofing” is that 2 of the 4 “walls” are glass!!
The space is roughly 10m L x 3.6m W x 2.5m H - the windows/glass panes are about 1250mm x 2450mm inside aluminium frames (depth of the frames is roughly 105mm)
I need to figure out the best (and cheap enough) way to mitigate sound transferring out of my space into the common areas/hallway (there is barely any foot traffic and almost all surrounding spaces on the level are empty.. but rather be safe than have my landlord on my ass)
My original thought was to purchase 6mm acrylic sheets and mount them on the aluminium frame to create an air gap (with acoustic sealing of course) and then most likely by some thick curtains to put over the windows to dampen the sound even further, but this starts climbing up in price quite quickly…
The alternative I had come up with (which I have no idea would even work like I’m thinking) is to purchase acoustic wood slat panels and attach them in place of the acrylic. Would this work at all/the same in terms of creating an air gap and also absorbing some of the sound?
This obviously needs to be a temporary fix (and cannot be a full structural reset like I know it actually requires) as obviously I am just leasing and when/if I have to move out of the space it all needs to be able to come down.
Any opinions on this would be welcome, I’ve sent myself insane reading a million forums and trying to figure this out for myself, so just a direct answer to my specific scenario would be much appreciated.
