RPG Continually Evolving
RPG will be closed during its annual summer shutdown from August 11-15th. Summer is a productive time for research at RPG when we welcome summer interns. This year we are pleased to have Dr. Jonathan Rathsam join us for a second time, following completion of his Ph.D. from Lily Wang's program at Nebraska. We are also expanding our testing facilities to include new impedance tubes, fabric testing, diffusion and scattering coefficients for new and exciting products. This fall we will be welcoming many visits by architects and acousticians for our Continuing Education Series of Diffuse Seminars. If you would like to join us, please contact RPG or a Rep in your area.

Introducing the CDM-ISO-PSJ and CDM-ISO-PRJ
The patent pending CDM-ISO-PSJ-L and CDM-ISO-PSJ-H (solid elastomers) and CDM-ISO-PRJ-L and CDM-ISO-PRJ-H (spring isolators) are used to resiliently suspend lightweight plasterboard ceilings to a joist floor, thereby maximizing the ceiling height and minimizing the transmission of audible energy. The design loads and resonant frequencies of the CDM-ISO-PSJ-L and CDM-ISO-PSJ-H hangers are 34 Lbf/14 Hz and 79 Lbf/12.8 Hz, respectively. The design loads and resonant frequencies of the CDM-ISO-PRJ-L and CDM-ISO-PRJ-H hangers are 56 Lbf/4 Hz and 112 Lbf/5 Hz, respectively. Static and dynamic stiffness and creep tests are available on request. Please contact Tom Ryan, Director of RPG's Noise and Vibration Division, for more information. We also invite you to visit our website and download the RPG-CDM Room Isolation System brochure.

Topakustik at Blue Cross Blue Shield
This A.W. Perry development, in Hingham, MA is a 327,000 s.f. facility completed in August, 2007 for Blue Cross Blue Shield of MA. The building was certified LEED-Silver, under the United States Green Building Council's Leadership in Energy and Environmental Design. Home to approximately 1,200 BCBS of MA associates, it includes a state-of-the-art data center, on-site food service, day care facility, and a five-level parking garage. The project was managed by RPG's Boston rep Alison Carrig, Hamilton Associates, the subcontracting installer was Allan Construction, along with the GC, Turner Construction. The Architect was Margulies & Associates of Boston, MA. < palign="left"> RPG Europe in Paris
RPG Europe exhibited a comprehensive range of products at the joint international meeting Acoustics08, sponsored by the ASA, EAA, SFA and National Societies of Europe in Paris. In addition, Dr. Peter D'Antonio chaired a session on "Low Frequency Control in Rooms" along with co-chair Dr. Christian Nocke. The meeting and exhibits were very well attended and Paris did it's best to entertain all in attendance.
