Download or read book Acoustical Materials written by Pranab Saha and published by SAE International. This book was released on 2021-08-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise. In Acoustical Materials, readers will grasp the science of reducing sound and vibration using sound absorbers, sound barriers, and vibration dampers. Sound provides information on the proper operation of the vehicle, but if unchecked, can detract from the consumer experience within the vehicle and create noise pollution outside the vehicle. Acoustical Materials provides essential information on the basics of sound, vehicle noise source, how these are measured, how vehicle owners perceive sound, and ultimately, how to solve noise problems in vehicles using sound package materials.
Download or read book Loudspeaker Modelling and Design written by Geoff Hill and published by Routledge. This book was released on 2018-09-03 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Geoff Hill demonstrates modern software and hardware being applied to the processes behind loudspeaker design and modelling. Modern computing power has progressed to the point that such analyses are now practical for any interested individual or small company. Loudspeaker Modelling and Design: A Practical Introduction examines the process from initial concept through specifications and theoretical simulations and onto detailed design. It demonstrates the processes of design and specification, by using detailed simulations of a loudspeaker driver; sufficient to give re-assurance that a design is practical and will perform as expected.This book brings together many different strands of modelling from electro-magnetic through to mechanical and acoustic, without getting bogged down in theoretical discussions and arguments. This practice-based book shows the techniques used in designing modern loudspeakers and transducers.
Download or read book Room Acoustics written by Heinrich Kuttruff and published by CRC Press. This book was released on 2016-10-03 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well established as a classic reference and specialised textbook, since its first publication in 1973, Heinrich Kuttruff’s Room Acoustics combines detailed coverage with a state of art presentation of the theory and practice of sound behaviour in closed spaces. This sixth edition presents several additional new sections, for instance on the reflection of a spherical wave from a wall, on finite element methods for sound field calculation and on virtual reality, as well as giving an overhaul of the standard material. Particular emphasis is given to the properties and calculation of reverberation, the most obvious acoustical feature of a room. And further key topics include the various mechanisms of sound absorption and their practical application as well as scattering by wall irregularities including pseudo-stochastic structures. Extensive space is given to of psychoacoustic insights and the quality criteria derived from them, along with new procedures for the sensory assessment of concert hall acoustics. As in earlier editions, one full and updated chapter is devoted to the design and performance of electroacoustic systems which nowadays is not just a method for sound amplification but offers many possibilities for correcting acoustic deficiencies and modifying a hall’s natural acoustics.
Download or read book Concert Hall Acoustics written by Yoichi Ando and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The acoustic quality of a concert hall has frequently posed a mysterious puzzle, namely, what physical aspects of the sound field can produce superior sound for the listener. The author has been probing for more than adecade into the subjective qualities preferred for musical and speech sounds. The result of his extensive investigations - the discovery that four and only four independent parameters contribute effectively to good acoustics - is summarized in the present book. The capability of calculating acoustical quality at any seat in a proposed concert hall is a unique and quite useful aspect of Ando's design method. Alternative architectural schemes can be compared based on the number of seats which exceeds a previously accepted minimum standard of acoustical quality.

Download or read book Acoustics in the Built Environment written by Duncan Templeton and published by Butterworth-Heinemann. This book was released on 1993 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Acoustics in the Built Environment is an invaluable work of reference for the building professional, covering all aspects of acoustics. It is unique in its range of topics: the environment, transport infrastructure, building design, building systems and buildings in use. Each section has been contributed by an expert in the field, and has been written in the light of recent developments such as the Environmental Protection Act and the Health and Safety Executive's Noise at Work Regulations for minimizing hearing damage." "The book presents information relevant to the day-to-day work of project design teams in a concise, readily accessible and usable form. Frequent reference is made to appropriate Standards, Acts of Parliament and other prescriptive documents, which can be cited in performance specifications." "Its broad range of subject matter and its ease of use make Acoustics in the Built Environment an indispensable source of information for anyone concerned with building acoustics, whether they are architects, planners, engineers or environmental health officers."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

With new contemporary case-studies, this updated book explores these characteristics as an important resource for architects, engineers and auditorium technicians. Supported by over 40 detailed case studies and architectural drawings of 75 auditoria at a scale of 1:500, the survey of each auditorium type is completed with a discussion of current best practice to achieve optimum acoustics.
Download or read book Acoustic Absorbers and Diffusers written by Trevor J. Cox and published by CRC Press. This book was released on 2009-01-26 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of rooms, semi-enclosed spaces and the outdoor environment. Their correct use is important for delivering high quality acoustics. Unique and authoritative, this book decribes how to effectively measure, model, design and apply diffusers and absorbers. It is a resource for new and experienced acousticians, seeking an understanding of the evolution, characteristics and application of modern diffusers. Absorption is a more established technology and so the book blends traditional designs with modern developments. The book covers practical and theoretical aspects of absorbers and diffusers and is well illustrated with examples of installations and case studies. This new edition brings Acoustic Absorbers and Diffusers up-to-date with current research, practice and standards. New developments in measurement, materials, theory and practice since the first edition (published in 2004) are included. The sections on absorbers are extended to include more about noise control.
