Acoustic diffusion is a necessary element in the realm of room acoustics; with its high commercial cost, it can be hard for a sound designer to afford a sufficient amount to treat their personal studio. This paper addresses this situation for the DIY community to offer alternative methods to effectively and efficiently create diffusors with a much smaller overall cost.

The methods that are examined throughout this paper will revolve around the use of 3D printing, an increasingly more common mode of production in households, as well as the use of closed cell and spray foam to mold around/inside of the 3D printed diffusor segments. This paper will analyze the cost, time, and overall diffusive efficacy of the production methods mentioned.
