 When I was on site last week, I had the chance to review the supplemental acoustic treatment installation in the 4th Floor HOTB Gallery.  I would like to express how thoroughly impressed I was with the detail and completeness of this install.  It went above and beyond our minimum requirement, and this will have a direct beneficial effect on the overall quality of sound in those parts of the Gallery.

Hopefully, I can shake the hand of your subcontractor who led this effort and truly share our appreciation by letting him know that I consider this to be a textbook example of retrofitting sound-absorptive treatment onto an existing ceiling.  We expect to use this example in the future to a lot of existing facilities troubled by bad acoustics, so they can visualize what is possible.
