Does anyone here have experience gauging noise levels for rooms or work with vendors who do?

We're wondering about the noise levels in the Pavilion Room at The Ritz-Carlton Dallas, Las Colinas - any insight would be great. We'd also be curious to know how to go about assessing it and if they have preferred companies/vendors/tactics for noise management. Anything we can learn would be helpful. We're pretty unsure of how to gauge this aspect of the venues we tour/vet for because many other events aren't similar enough to ours so going into a room when there is a reception of a large conference, or a wedding, for example, don't give us a comparable view.

hi all!! i’m hosting a few intimate exec/client dinners (10 guests) in a couple cities, does anyone have any recommendations for good private dining rooms in atlanta, near perimeter center (trying to stay near our client) or dallas downtown?
