Help with Motor Decibel Ratings

[caneng2002]

I'm looking for decibel ratings for NEMA motors to compare a 600 kw tefc to WP1 enclosure.

If NEMA has a maximum rating for all motors that would be fine as well.

For those needing more information on why I'm asking. Its for a pumping station design where I think 600kw tefc will be too noisy in the room compared to WPI motors.

Thanks
