acoustic enclosure body
What is an acoustic enclosure? An acoustic enclosure (also known as a soundproof enclosure, sound enclosure or noise enclosure) encloses noisy equipment in a room or a chamber.
Basically, you want to build a 5-sided box with an open bottom to go over the widget. Use two layers of 5/8″ particle board with Green Glue in between and screw them to a simple 1×1 frame inside the box. Line the inside of the box with 1-3/8″ thick mass loaded vinyl composite foam.
