Thanks to Zach Frame for assisting with construction of the slanted chamber wall (pictured right). This wall is further away from the foundation wall towards the back of the chamber and closer to it at the front. This was constructed this way to aid in canceling standing sound waves (which occur when two walls are parallel to each other). A standing wave will cancel frequencies out and therefore undesirable in an instrument such as this. The furring strips on the rest of the walls will hold 1/2" drywall whereas the ceiling will have two sheets of 5/8" drywall with green acoustic glue in between. The glue creates an air gap between the two sheets which helps to dampen the sound from penetrating the ceiling. The furring strips offer further assistance in this area as does the fiberglass insulation.
