Reybold Venture Group Project Location:
Bear, Delaware Highlights: - Detailed FHA Noise Study
- Sound Mitigation Recommendations
Lewis S. Goodfriend & Associates completed an acoustical analysis for ten apartment buildings to satisfy the Department of Housing and Urban Development (DHUD) FHA mortgage application requirements. Nearby sound sources included aircraft from a nearby civilian and military airport, and an adjacent Norfolk Southern freight train route. While most of the buildings were found to have an acceptable acoustical environment by DHUD guidelines, a few buildings adjacent to the railroad track were found to be normally unacceptable. Recommendations were made to improve the sound isolation provided by the faades of these building, resulting in an acceptable acoustical environment. LSG&As acoustical report and supporting documentation helped to get all ten apartment buildings approved for FHA mortgages.

Medarex/Bristol-Myers Squibb Generator Relocation
Client Name:
Medarex Project Location:
Bloomsbury, New Jersey / New Brunswick, New Jersey Highlights: - Source Sound Pressure Level Measurements
- Ambient Sound Pressure Level Measurements
- Detailed Acoustical Modeling
Lewis S. Goodfriend & Associates completed an acoustical evaluation of a generator slated to be relocated from a Medarex facility to a Bristol-Myers Squibb facility. Measurements of the generator were performed at the Medarex location, and projected from the proposed Bristol-Myers Squibb location to the nearest residential and commercial property lines.
