I was looking at the Epilog Laser site and saw that the new machines are touting 59 DB for their new quiet/low noise fans. I got curious and decided to measure the sound of the engraver fans in my shop and was surprised by the result. My machine is 3 years old. Distance away from fan is 1 foot at measuring point. - the second one if when the exhaust blower is on, same distance from blower. So, I guess I won't sweat the noise from the laser engraver fans.

I am an audio nut and was about to ask you what SPL meter that was since I have never seen it... but they have an app for that...

In the end SPLs rarely mean anything from a manufacturer unless it is done to a specific standard, distance and the environment make such a difference.

Yes, you are correct - it is an app - but very retro and albeit somewhat inaccurate, it does give you and idea on what the levels are, so to hear.
