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

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.

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? 

Just a reminder - there are (at least) three issues for windows and sliding glass doors. One is reflections, the second is the vibration of the glass produced by acoustic waves. Therefore, multiple methods must be employed. The third issue is RFI/EMI for which glass is transparent.  RF enters freely from the great outdoors or, in the case of interior glass doors, from adjacent rooms. 

Jorsan,

Again, from an overall acoustics balance, they are awesome. They will reduce resonance modes, and allow better room/speaker/woofer integration, which will make everything sound in better balance, and improve the perceived signal to noise by reducing the resonance time fairly broadly. They just happen to be a lot better in the bass than most devices their size.

I'm not suggesting these as your 1 thing to do.

Strongly encourage you to ask GIK for help directly.

But also, you may learn a lot by throwing some pillows and blankets around the floor. It's free and you'll get a better idea of how interrelated room acoustic treatments really are.

Best,
