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.

Looking for a videographer for a conference in Dallas Nov 8-9. Any recommendations? It’s for an early stage VC conference held at the Deloitte Campus in West Lake

HI all! Any recommendations for great, modern, convention hotels or venues in these target locations: Denver, Dallas, Chicago, Nevada (not Las Vegas). Attendee counts are at 1000ppl Thank you!
