Book Description
Presents the results of a measurement study performed at a highway noise barrier site located along Interstate 495 in Montgomery County, Maryland. The objective of the study was to measure the degradation in acoustic performance of a highway noise barrier due to the close proximity of a parallel barrier on the opposite side of the roadway. The test site selected for measurements consisted of a contiguous arrangement of two parallel reflective noise barriers followed by a single noise barrier. Five-minute, energy-averaged, A-weighted noise levels were computed from data measured simultaneously at identical heights and offset positions behind the single and parallel barrier arrangements. A comparison of the measured and predicted results is presented.

Book Description
As a comprehensive reference dedicated to sound and vibration in buildings, Building Acoustics and Vibration addresses the basic and advanced principles that can be used to solve practical and theoretical problems typically encountered in building and architectural acoustic practices. In addition, physical and mathematical concepts are introduced and developed sufficiently to make this publication a self-contained and up-to-date source of information for readers. Building Acoustics and Vibration is a must-have textbook for engineering students, engineers, and consultants involved in the sound, vibrations and building environment. With comprehensibility and versatility in the presentation of knowledge, this highly anticipated publication will easily fill the gap in the literature of building engineering and sciences, which presently lacks an authoritative guide on the theoretical and practical aspects of building acoustics and vibration.
