Logistics Distribution Facilities, Nationwide

These projects involve evaluation of site noise and acoustical impact from heavy trucks, delivery vehicles, and stationary noise sources. Consultations involve on-site and neighborhood measurements of sound levels, computer modeling of existing and/or future site sound emissions, and analyses of potential mitigation measures.

Housing Feasibility, Somerville, New Jersey

A developer undertook a feasibility study of proposed multi-family housing adjacent to a railway, with concern regarding the need for and feasibility of appropriate sound-isolating constructions. OAA conducted on-site measurements of train noise at multiple distances from the train tracks, including the noise of horn soundings as trains approached a nearby grade crossing. Building envelope constructions necessary for appropriate attenuation of train noise were investigated and presented to the developer.

TVA Operation Center, Meigs County, Tennessee

The design of this sprawling operations center for command and control of the Tennessee Valley Authority electrical grid involved evaluation of exterior noise from rooftop air handlers, ventilation louvers, dry coolers, emergency generators, and a load bank. Design criteria at noise-sensitive receptors were complicated by an extremely low ambient nighttime sound level.

Westfield Rink, Westfield, New Jersey

Neighborhood complaints regarding noise from a seasonal ice rink atop basketball courts at Gumbert Park prompted an acoustical investigation involving site measurements, observation of rink activities, and modeling of candidate noise control measures.

The Seeing Eye, Morris Township, New Jersey

OAA analyzed existing and future sound emissions in order to evaluate the potential community noise impact of dog barking sound, and provided recommendations for noise control. Expert witness testimony was provided to the local municipal board in support of the application.

Restaurant Music Noise Prediction, Edison, New Jersey

OAA predicted outdoor sound levels from a proposed restaurant location in an area already sensitized to noise from a different use. Computer modeling of sound propagation from the restaurant was combined with assessments of the daytime and nighttime ambient sound levels in order to develop findings. Expert witness testimony was presented to the municipal board in support of the restaurant’s application, and the application was approved.
