Woman Installing Sound Panels In Echo Chamber

View through an open door into a small square room, inside is the character, in the process of putting up square foam sound-proofing panels on the walls, about half of the rooms walls are covered with them. She looks over her shoulder at the viewer with a smug smirk or grin. She's holding one of the foam panels and a glue gun at the ready. A light-up sign above the door states "Echo Chamber".
