Thanks! Yes it’s cork wall board. It wasn’t too hard to put up and it makes a huge difference to the room acoustics. Sitting in my room in dead silence my db meter reads around 27db which is pretty quiet.
Okay, this has been driving me crazy this morning so I have to ask: is that cork wallpaper of some kind on the side wall? If so, I really like it and didn’t know such a thing existed until this morning while googling. Love the coziness of the room and selected gear, too!
