Town of Norton Truck Storage and Maintenance Facility

SERVICE:

Noise Peer Review

DESCRIPTION:

Tech Environmental Inc. (Tech) was retained by the Town of Norton, MA to do a peer review of a sound study for the new Waste Management Inc. Truck Storage & Maintenance Facility in Norton, MA. The sound study focused on the potential noise impacts from truck back-up alarms on nearby residences approximately 600 and 1,000 feet away. It also assessed the potential sound reduction capabilities of 10-, 16- and 20-foot high sound wall options, and made a recommendation to install a 20-foot high sound wall.

Tech examined the noise modeling calculations of the original sound study to verify their accuracy and completeness. Tech also reviewed the recommended sound wall designs and their potential to reduce back-up sound levels. Tech recommended that sound walls by themselves could provide reasonable but not optimal sound reductions of tonal sounds. Tech also recommended replacing the existing single-frequency backup alarms with broadband white sound backup alarms, which would provide a less annoying sound impact for adjacent residences.
