Roy Carroll's Center Pointe, Then and Now

Before, with smaller windows and more sound muffling construction;

What was
 

After, with windows of unknown quality, from floor to ceiling on the exterior;

What is now

Why won't Roy disclose the quality of his windows?

Could much of the downtown Greensboro noise issues have come from self inflicted wounds?

Was Center Pointe designed for residential use?

Did the building previously have white noise machines above the ceiling tiles?

Was there an acoustical study done?

If there were no noise prevention standards applied to the exterior...?

How thick is the glass?

Acoustical Window Seals?;

"Sound transmission into building spaces is generally through the weakest element, and the weakest element is usually the windows.

The resistance of a building material to the transmission of sound is called the sound transmission loss (TL).

When usual glazing configurations are not sufficient to limit the transmission of sound into building spaces, glazing configurations with enhanced sound transmission losses, or acoustical glazing, must be considered."

Was acoustical glazing considered?

What is the STC rating on the windows?
