Next, I built a cover to go over the hole on the engine side of the box. Since sound does not like going around corners, this substantially reduces the noise. In the pic, the cover is framed with 1x2s, but I subsequently changed to 1x4s for more airflow. I also plan to carpet that piece of plywood to further reduce noise.
