Damage to structures due to vibrations from pile driving operations is of great concern to engineers. This research has stemmed from the need to address potential damage to concrete-filled pipe piles and recently placed concrete structures that could be affected by pile driving vibrations. The study will focus on two topics: (1) The attenuation of potentially damaging pile driving vibrations with distance from the source, and (2) The effects of distance and curing time of concrete on the quality (unconfined compressive strength) of recentlyplaced concrete exposed to pile driving vibrations. The effects of pile driving vibrations did not cause problems with concrete compressive strength except for the case where concrete had only cured for 4 to 6 hours before vibration.

The entire field of construction-induced vibrations - including advances in earthquake engineering, nuclear blast protective design, and construction and mine blasting - is covered in this work. Frequency of vibration and strain form the foundation for the presentation of the material.

This manual provides direction for the preparation of noise and vibration sections of environmental documents for mass transportation projects. The manual has been developed in the interest of promoting quality and uniformity in assessments. It is expected to be used by people associated with or affected by the urban transit industry, including Federal Transit Administration (FTA) staff, grant applicants, consultants and the general public. Each of these groups has an interest in noise/vibration assessment, but not all have the need for all the details of the process. Consequently, this manual has been prepared to serve readers with varying levels of technical background and interests. It sets forth the basic concepts, methods and procedures for documenting the extent and severity of noise impacts from transit projects.

Because environmental acoustics has a complex mathematical basis,it is often difficult to determine whether acousticalrecommendations are valid. Handbook of Environmental Acousticssimplifies this decision-making process and provides easy-to-followexplanations of acoustic terminology, noise control design, andregulatory noise issues. The book clarifies key aspects ofenvironmental noise in basic language, covering: * Common noise sources--including the risk of exposure to commondaily environmental noise sources * Current noise regulations, guidelines, andstandards--illustrating all key points * Acoustic terminology and environmental noisedescriptors--providing a foundation for understanding noiseissues * Effects of noise on people and animals--emphasizing theimportance of restricting noise exposure * Relevant noise rating methods--clarifiying the use of noisemetrics * Construction and building code requirements--explaining currentrequirements and featuring tips on how to avoid privacyproblems * Measurement considerations--demonstrating standard methods andoffering practical advice on how to ensure proper measurementprocedures * Noise control designs--detailing source-path-receiver systems andnoise control fundamentals In addition to traditional noise control methods, new areas, suchas active noise control, sound intensity measurement, and diffusivedesigns, are explained. A sample municipal noise ordinance helpsthe user to draft an ordinance tailored to the needs of aparticular community. Avoiding complex mathematics and analyses,Handbook of Environmental Acoustics is a user-friendly manual forurban planners, municipal officials, engineers, attorneys,industrial hygienists, architects, environmental professionals, andstudents in these fields.
