Sound quality research is an emerging field of acoustics, and it has broad application prospects in the field of vibration and noise control of machinery and automobiles. With the development of new energy vehicles in recent years, the technology demand for interior sound quality evaluation and control has increased rapidly.
This book comprehensively introduces the basic concepts, theories, methods and the latest research progress in evaluating and controlling vehicle interior sound quality. The contents include the generation mechanism of the sound field in the vehicle, the evaluation index of the sound quality, the subjective and objective evaluation method, the neural network evaluation model, the data pre-processing, the active and passive control method, the vibration control method based on the piezoelectric effect, the hybrid vibro-acoustics active control method for interior sound quality and the system of sound quality evaluation and control, etc. It contains an introduction to basic knowledge and theoretical models and a detailed description of the research background, the algorithms implementation methods and the technical status of specific issues.
Yansong Wang has been engaged in teaching and scientific research on vehicle sound quality evaluation and control for many years and has achieved significant progress in vehicle NVH technology, environmental noise evaluation and control, acoustic material testing and noise reduction equipment. In basic theoretical research, he proposed several intelligent evaluation methods for non-stationary signals, established intelligent evaluation models of noise comprehensive annoyance based on psychoacoustic parameters, and proposed a hybrid vibro-acoustics active control method for interior sound quality. Prof. Wang has successively completed more than 40 various scientific research projects, including 4 projects from the National Natural Science Foundation of China, and has won more than 10 scientific research awards; he is the author of more than 170 papers/books/book chapters, he is currently a Member of the IEEE, IIAV Society, China Ordnance Society, China Society of Automotive Engineering, China Society for Environmental Sciences and the Acoustics Society of China.
Hui Guo has been engaged in teaching and scientific research on vehicle sound quality evaluation and control for years and has achieved significant progress in vehicle NVH technology, acoustic metamaterials and piezoelectric metamaterial.

In the past decade, he has published more than 30 SCI papers.
Dateiformat: PDFKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
