Uris Computer Lab
Sound Level Analysis
Unless there is a class, CL3 is relatively quiet. More talking and interaction can be seen in the Uris computer lounge at all times. Possible explanations include its open/bright atmosphere, ability for people to walk through to get to/from the Cocktail Lounge, and to the shape of the computer desks.
