The objective of this study is to access and quantify the prediction means for traffic noise. Of particular interest is the noise reduction behind noise walls, referred to as the shadow zone. The study measured traffic noise at four sites in the metropolitan Chicago area with noise barriers. These four sites were modeled with both STAMINA 2.0 and FHWA Traffic Noise Model (TNM) 1.0. For these four sites, TNM predicted the observed traffic noise more accurately than STAMINA. In general, STAMINA overpredicted the traffic noise relative to the measured values. The second objective of the study was to access the state-of-the-art of top treatments for noise walls. Top treatments are an addition to a traditional noise wall to increase the effectiveness without significantly increasing the cost or height of the noise wall. It appears that top treatments are not well enough developed for consideration in Illinois at this time. The last objective was to develop a means to help educate the general public about traffic noise and noise wall characteristics. To meet this objective, two means were developed. The first was a home page that provides great flexibility due to the hypertext format. The second was a tri-fold brochure to serve as a handout at public meetings or as a visual aid for one-on-one discussions.

Download Design of Wood Highway Sound Barriers Book in PDF, ePub and Kindle
As new and existing U.S. residential areas and high volume highways continue to intermingle, traffic noise abatement procedures continue to be important. This study investigated the acoustic effectiveness, public acceptance, and structural requirements of various designs and types of sound barriers. In addition, the acoustic effectiveness of a prototype sound barrier is reported. Results are presented on the acoustic effectiveness from in situ measurements of one cement bonded composite panel barrier and four precast concrete, two plywood, two glued-laminated, and three post and panel barriers. The research on public acceptance of sound barriers focused on the perception of visual compatibility. Based on results from semantic-differential and individual ratings, wood and concrete barrier designs were perceived to have favored gbsruralgcs qualities. Data collected during the research on acoustic effectiveness and public acceptance were used to develop structural requirements and construction details for a prototype wood sound barrier. The prototype wood sound barrier provided insertion losses of 15 dB or greater, exceeding the 10-dB acceptable performance for a highway sound barrier.

Download Engineering Noise Control Book in PDF, ePub and Kindle
This classic and authoritative student textbook contains information that is not over simplified and can be used to solve the real world problems encountered by noise and vibration consultants as well as the more straightforward ones handled by engineers and occupational hygienists in industry. The book covers the fundamentals of acoustics, theoretical concepts and practical application of current noise control technology. It aims to be as comprehensive as possible while still covering important concepts in sufficient detail to engender a deep understanding of the foundations upon which noise control technology is built. Topics which are extensively developed or overhauled from the fourth edition include sound propagation outdoors, amplitude modulation, hearing protection, frequency analysis, muffling devices (including 4-pole analysis and self noise), sound transmission through partitions, finite element analysis, statistical energy analysis and transportation noise. For those who are already well versed in the art and science of noise control, the book will provide an extremely useful reference. A wide range of example problems that are linked to noise control practice are available on www.causalsystems.com for free download.

Download Basic of sound and hearing Part 4 building acoustics Book in PDF, ePub and Kindle
Building acoustics is the science of controlling noise in buildings. This includes the minimization of noise transmission from one space to another and the control of the characteristics of sound within spaces themselves. Building acoustics are an important consideration in the design, operation and construction of most buildings, and can have a significant impact on health and wellbeing, communication and productivity. They can be particularly significant in spaces such as concert halls, recording studios, lecture theatres, and so on, where the quality of sound and its intelligibility are very important. Building acoustics can be influenced by: The geometry and volume of a space. The sound absorption, transmission and reflection characteristics of surfaces enclosing the space and within the space. The sound absorption, transmission and reflection characteristics of materials separating spaces. The generation of sound inside or outside the space. Airborne sound transmission. Impact noise.

Download Architectural Acoustics Illustrated Book in PDF, ePub and Kindle
Unite the science of sound and the principles of design to enhance any space Architectural Acoustics Illustrated translates the quantitative and qualitative content of acoustics into the graphic language of architecture. This highly-visual guide includes over 350 illustrations that outline the physics of sound and the best design practices for limiting or mitigating noise in buildings by using the latest in materials and techniques. Each chapter includes a summary checklist of design guidelines to help prevent mistakes and oversights, and the Instructor's website offers video animations demonstrating acoustical concepts. Designed as a "first look" at the interaction of sound and space, the book explains the principles of architectural acoustics and their practical applications, providing a comprehensive guide for designing with acoustics in mind. Architectural acoustics is more than just concert halls – it may determine building placement, division of interior space, exterior construction, and even siting. When addressed early in the design process, the resulting space can be free of unwanted sound and promote good hearing; if left unaddressed, the problems with the space can lead to lawsuits and costly post-construction remediation. Architectural Acoustics Illustrated helps designers solve most acoustical problems in advance, by enabling readers to: Understand the physical science underlying the behavior of sound Consider the interactions of sound and space in the initial design approach Mitigate building sounds such as those produced by HVAC and plumbing with early design planning Design spaces for listening, and incorporate acoustics best practices into every plan The highly visual format of the book helps readers grasp complex concepts quickly, and thorough discussion of each concept's real-world application ties the science directly into the design process. All design professionals need to have a fundamental understanding of acoustics, and Architectural Acoustics Illustrated is a comprehensive, practical guide in an easy-to-read format.
