Soundproofing a bedroom which was a former dining room

[concerned]

My bedroom was built from a dining room off of kitchen.  So one of the walls in the bedroom has three glass panels at the top half and a dry wall at the bottom (on the kitchen side is kitchen cabinets).   You can fold these glass panels and can use the kitchen counter to serve food into the bedroom.  So there are many gaps between these glass panels and the bottom dry wall. The length of the glass panels is 52” by 139” and the drywall is1.5” thick.  What can be done to make this sound proof?

The door into this bedroom is actually sliding single pane glass doors (can slide to both sides) off of kitchenette dining.  How do we make this sound proof for this sliding glass door?

Landlord does not want any structural changes – so needs temporary solution and wants it to be cost effective since we will be leaving in one year.  Want privacy and quietness.

Thanks for your help

Sound dampening curtains would be the only cost effective method here.
Heavy vinyl curtains or have 1/4" ssp mat sewn in to improve the reduction, keep in mind 50% pleeting is the key to a greater reduction.
