Someone made a noise baffle ages ago, I wonder if something like that would help?
Ah, there we go, @takitus was the one who posted.
I wanted to continue to cut down on the noise output from the glowforge. The major issue I had was the vent holes on the bottom of the unit reflect sound right off of the table top and out the air gap between the unit and the table.
I initially tried putting up some semi sound reflective walls to see if it would help. It did help a little, but was more trouble than it was worth, and I didnt want to restrict air flow. The next step was to make an inset an-echoic like chamber for the glowforge to…
I think the idea was to reduce sound inside , but maybe some sort of baffle post-exhaust would do the trick, if you could do it without impinging airflow too much?
