Download or read book Promoting Healthy and Supportive Acoustic Environments Going beyond the Quietness written by Francesco Aletta and published by MDPI. This book was released on 2020-11-04 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers 14 original contributions published in an IJERPH Special Issue that deal with the perception of environmental sounds and how such sounds are likely to affect human quality of life and well-being and the experience of a place. The research focus over the years has been gradually shifting from treating sound simply as “noise” and something that cities should get rid of to a potential “resource” to promote and support community life in public spaces. Three main topics or “needs” to be addressed by researchers and practitioners emerged from this Special Issue: (1) the need to re-think “quietness” in cities as something that goes beyond the mere “pursuit of silence”, (2) the need to integrate additional contextual factors in the characterization and management of urban acoustic environments for public health, and (3) the need to consider the acoustic quality of indoor spaces as opposed to an outdoor-only perspective. The contributions collected in this book will hopefully trigger new questions and inform the agenda of future researchers and practitioners in the environmental acoustics domain.

Download or read book Acoustic Environments of the F 111A Aircraft During Ground Runup written by John N. Cole and published by . This book was released on 1968 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sound pressure level measurements were made on an F-111A aircraft at 250-foot radial distance with three different engine power configurations at Wright-Patterson AFB, Ohio. In addition, sound level measurements were made at four maintenance positions where personnel would typically be located during normal ground operations. These data were used to compute the power spectra, directivity indices, equal sound pressure level contours, equal perceived noise level contours, and equal speech interference level contours. These results are presented in graphical form and can be used to determine the acoustic environments at distances from 125 to 6000 feet from the aircraft during ground operation. (Author).

Download or read book Directivity Based Multichannel Audio Signal Processing For Microphones in Noisy Acoustic Environments written by Simon Grimm and published by Springer. This book was released on 2019-01-28 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simon Grimm examines new multi-microphone signal processing strategies that aim to achieve noise reduction and dereverberation. Therefore, narrow-band signal enhancement approaches are combined with broad-band processing in terms of directivity based beamforming. Previously introduced formulations of the multichannel Wiener filter rely on the second order statistics of the speech and noise signals. The author analyses how additional knowledge about the location of a speaker as well as the microphone arrangement can be used to achieve further noise reduction and dereverberation.

Download or read book Soundscape and the Built Environment written by Jian Kang and published by CRC Press. This book was released on 2018-10-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soundscape Basics and Practical Implications Soundscape research represents a paradigm shift, as it involves human and social sciences and physical measurements to account for the diversity of soundscapes across countries and cultures. Moreover, it treats environmental sounds as a resource rather than a waste. Soundscape and the Built Environment is the first book to systematically discuss soundscape in the built environment. It begins with a presentation of theory and basic background, answering questions such as: what is soundscape, how is it important, and how does it affect people in terms of their health and perception on the acoustic environment. The book then sets out tools for implementing a soundscape approach, with measurement techniques, mapping, and good soundscape practices. It also delivers a series of examples of the application of the soundscape approach in planning, design, and assessment. Discusses soundscape and environmental noise Explores cultural variations and the way they influence soundscape Introduces binaural measurement technology and psychoacoustics Examines the physical, psychological, and physiological restorative mechanism of high-quality acoustic environments Presents soundscape mapping based on human perception of sound sources Includes real-world examples and case studies highlighting the key issues in soundscape intervention Soundscape and the Built Environment is written by a group of leading international figures and derives from a four-year EU COST project on Soundscapes of European Cities and Landscapes. It presents a consensus on the current state of the art and is not merely a collection of different views. It is written for acoustic consultants, urban planners, designers and policy makers, as well as for graduate students and researchers.

Download or read book Soundscapes Humans and Their Acoustic Environment written by Brigitte Schulte-Fortkamp and published by Springer Nature. This book was released on 2023-04-24 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Acoustic Sensing Techniques for the Shallow Water Environment written by Andrea Caiti and published by Springer Science & Business Media. This book was released on 2006-09-21 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the collection of papers from the second workshop on Experimental Acoustic Inversion Techniques for Exploration of the Shallow Water Environment. Acoustic techniques provide the most effective means for remote sensing of ocean and sea floor processes, and for probing the structure beneath the sea floor. No other energy propagates as efficiently in the ocean: radio waves and visible light are severely limited in range because the ocean is a highly conductive medium. However, sound from breaking waves and coastal shipping can be heard throughout the ocean, and marine mammals communicate acoustically over basin scale distances. The papers in this book indicate a high level of research interest that has generated significant progress in development and application of experimental acoustic inversion techniques. The applications span a broad scope in geosciences, from geophysical, biological and even geochemical research. The list includes: estimation of geotechnical properties of sea bed materials; navigation and mapping of the sea floor; fisheries, aquaculture and sea bed habitat assessment; monitoring of marine mammals; sediment transport; and investigation of natural geohazards in marine sediments. Audience This book is primarily intended for physicists and engineers working in underwater acoustics and oceanic engineering. It will also be of interest to marine biologists, geophysicists and oceanographers as potential users of the methodologies and techniques described in the book contributions.

Download or read book Smart Wireless Acoustic Sensor Network Design for Noise Monitoring in Smart Cities written by Rosa Ma Alsina-Pagès and published by MDPI. This book was released on 2021-01-15 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Noise Directive (END) requires that a five-year updating of noise maps is carried out to check and report on the changes that have occurred during the reference period. The updating process is usually achieved using a standardized approach consisting of collecting and processing information through acoustic models to produce the updated noise maps. This procedure is time consuming and costly, and has a significant impact on the financial statement of the authorities responsible for providing the maps. Furthermore, the END requires that easy-to-read noise maps are made available to the public to provide information on noise levels and the subsequent actions to be undertaken by local and central authorities to reduce noise impacts. In order to update the noise maps more easily and in a more effective way, it is convenient to design an integrated system incorporating real-time noise measurement and signal processing to identify and analyze the noise sources present in the mapping area (e.g., road traffic noise, leisure noise, etc.) as well as to automatically generate and present the corresponding noise maps. This wireless acoustic sensor network design requires transversal knowledge, from accurate hardware design for acoustic sensors to network structure design and management of the information with signal processing to identify the origin of the measured noise and graphical user interface application design to present the results to end users. This book is collection in which several views of methodology and technologies required for the development of an efficient wireless acoustic sensor network from the first stages of its design to the tests conducted during deployment, its final performance, and possible subsequent implications for authorities in terms of the definition of policies. Contributions include several LIFE and H2020 projects aimed at the design and implementation of intelligent acoustic sensor networks with a focus on the publication of good practices for the design and deployment of intelligent networks in other locations.
