This acoustics handbook for mechanical and architectural applications is a translation of the German standard work on the subject. It not only describes the state of art of engineering acoustics but also gives practical help to engineers for solving acoustic problems. It deals with the origin, the transmission and the methods of abatement of air-borne and structure-borne sound of different kinds, from traffic to machinery and flow induced sound.

Exposure to noise at home, at work, while traveling, and during leisure activities is a fact of life for all Americans. At times noise can be loud enough to damage hearing, and at lower levels it can disrupt normal living, affect sleep patterns, affect our ability to concentrate at work, interfere with outdoor recreational activities, and, in some cases, interfere with communications and even cause accidents. Clearly, exposure to excessive noise can affect our quality of life. As the population of the United States and, indeed, the world increases and developing countries become more industrialized, problems of noise are likely to become more pervasive and lower the quality of life for everyone. Efforts to manage noise exposures, to design quieter buildings, products, equipment, and transportation vehicles, and to provide a regulatory environment that facilitates adequate, cost-effective, sustainable noise controls require our immediate attention. Technology for a Quieter America looks at the most commonly identified sources of noise, how they are characterized, and efforts that have been made to reduce noise emissions and experiences. The book also reviews the standards and regulations that govern noise levels and the federal, state, and local agencies that regulate noise for the benefit, safety, and wellness of society at large. In addition, it presents the cost-benefit trade-offs between efforts to mitigate noise and the improvements they achieve, information sources available to the public on the dimensions of noise problems and their mitigation, and the need to educate professionals who can deal with these issues. Noise emissions are an issue in industry, in communities, in buildings, and during leisure activities. As such, Technology for a Quieter America will appeal to a wide range of stakeholders: the engineering community; the public; government at the federal, state, and local levels; private industry; labor unions; and nonprofit organizations. Implementation of the recommendations in Technology for a Quieter America will result in reduction of the noise levels to which Americans are exposed and will improve the ability of American industry to compete in world markets paying increasing attention to the noise emissions of products.

The concept of the “Soundscapes” includes all of the sounds in one’s environment and focuses not only on the sounds itself. Instead, it focuses on the interrelationships between person and activity and place, both in space and time. Soundscape also include influences on the acoustic environment through auditory sensation, its interpretation, and the responses to the acoustic environment in context. The conceptual framework of Soundscape describes the “process of perceiving or experiencing and/or understanding an acoustic environment, highlighting general concepts and their relationships: context, sound sources, acoustic environment, auditory sensation, interpretation of auditory sensation, responses, and outcomes” (International Organization for Standardization, ISO 12913-1:2014 Acoustics Soundscape Part Definition and Conceptual Framework, ISO, Geneva, 2014). With soundscape, one achieves a deeper understanding of acoustic environment and its effects on people. The ISO standard 12931-1 on soundscape provides an important, and rigorous, distinction in the use of “Soundscape.” But, it is recognizable that some individuals, particularly planners, designers, lay persons, and even those primarily interested in management of the acoustic environment through environmental noise control, will find it convenient to use “Soundscape” as a synonym for the physical acoustic environment. When it comes to noise management and urban planning, soundscape research has the potential to promote healthy urban environments by sharing and incorporating the significant knowledge of all concerned parties. Understandably, this shows that the communication with regard to noise management has to be forced to guarantee that the specifics of Soundscapes (i.e., the relevance of perception) are seriously considered alongside the whole. This book will bridge the gap between soundscape theory and practice and therefore it will be different from our earlier publications as “Soundscape and the built environment” (ed. by J. Kang and B. Schulte-Fortkamp CRC Press, Taylor and Francis Group, Boca Raton, Fl 2016) and also from the respective Special Issues on Soundscapes in 2012 in The Journal of the Acoustical Society of America (ed. by B. Schulte-Fortkamp and J. Kang), and also the Special Issue in Acta Acustica 2006 *(ed. by B. Schulte-Fortkamp and D. Dubois), and the E-book on soundscape This volume will be driven by the difficult process of standardization of Soundscape and its evaluation procedures. The main goal of the proposed volume is to present and review the developments in Soundscape, reflecting the standardization procedure and the diverse inputs. the needs in management and planning in urban acoustic environments, the book will also focus on the difficulties, as well as the solutions, in interdisciplinary grounded communication, that is, on the one hand, related to science, but on the other to application, that needs guidance.

Railway Noise and Vibration: Mechanisms, Modelling, and Means of Control, 2nd Edition provides a complete overview of the state of the art in rail noise and vibration theory and modelling. This book describes each source of noise and vibration, such as rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise in a systematic way, covering relevant theoretical modelling approaches and their practical implementation, with extensive examples of noise control technology applied at source. Noise and vibration are key obstacles to further development of railway networks worldwide for high-speed intercity traffic, freight and suburban metros and light-rail systems. With noise problems all too often dealt with inefficiently due to a lack of understanding of the problem, this new edition is an invaluable reference for all those working with noise and vibration from railways, whether in industry, consultancy, or academic research. • Introduces theoretical modelling approaches for each source in a tutorial fashion• Discusses the theoretical basis and practical applications of railway noise control technology, summarising the latest research and key findings from recent decades in one concise resource• Updated with new prediction models and methods, including more detail on ground vibration and aerodynamic noise

Thanks to advances in computer technology in the last twenty years, navigation system, cabin environment control, ACC, advanced driver assistance system (ADAS) and automated driving have become a part of the automobile experience. Improvement in technology enables us to design these with greater flexibility and provide greater value to the driver (human centered design). To achieve this, research is required by laboratories, automobile and auto parts manufacturers. Although there has been a lot of effort in human factors research and development, starting from basic research to product development, the knowledge and experience has not been integrated optimally. The aim of this book is to collect and review the information for researchers, designers and developers to learn and apply them for further research and development of human centered design of future automotive technologies. Automotive human factors include psychological, physiological, mathematical, engineering and even sociological aspects. This book offers valuable insights to applying the right approach in the right place.
