Sound Proofing Lab with 400 Hz Fan Noise
« on: September 30, 2001, 01:43:17 PM »
Hello,
I am the lab director for a large integration and test lab
that consists of 5 Test benches that each contain two units with 400 Hz Fans.
If you have ever heard this High pitch noise you will understand the concern.
I am looking for a solution that will dampen the noise in these benches without hindering the air flow.
I am open to more in depth information if anyone thinks they can solution this!
Thanks,
Rick Bell

Change the fans to quiet ones running on 60 cps.
