內容簡介
《有源噪聲控制（第二版）》本書是國防工業出版社2003年版《有源噪聲控制》的第2版，全面系統地介紹了有源噪聲控制的基礎理論、系統實現和工程套用。全書共11章。第1章評述了有源噪聲控制的發展歷程和主要技術特點，第2章和第3章總結了研究和套用有源噪聲控制技術所必需的聲學、振動聲輻射、自適應濾波和現代控制理論等方面的基礎知識。第4章~第6章介紹了有源控制器的結構、算法與實現。第7章~第10章分別研究了有源控制技術的主要套用領域，包括自由空間與封閉空間有源噪聲控制、結構聲輻射有源控制、有源聲學結構。第11章介紹了有源噪聲控制技術在實際工程中的套用情況，特別給出了有源耳機、飛機艙室與車內噪聲有源控制技術的套用現狀。本書集學術性和實用性為一體，不僅對從事噪聲與振動控制、信號處理及自動控制等工作的專業人員、高等院校教師和研究生有重要參考價值，而且對有志於開發聲學與振動新產品的人士有直接幫助。 This book is the second edition of Active Noise Control published in 2003 and by the National Defense Industry Press and introduces theoretical bases, system implementation, and engineering applications involved in active noise control. This book consists of 11 chapters. Firstly a brief history and characteristics for active noise control are reviewed in Chapter 1. Secondly, basic knowledge about acoustics, mechanical vibration and its sound radiation, adaptive filtering and modern control theory are summarized in Chapter 2 and 3 respectively. Thirdly, the structures and algorithms for adaptive active controllers are explored in Chapter 4, 5 and 6, and then in the following three chapters main application fields associated with active control of sound are examined respectively, including active control of sound in free space and enclosed space, active structural acoustic control and active acoustic structure, etc. Finally practical applications and the state of art for active noise control, including active earphone, active control of noise within aircraft and car cabin are introduced in detail in Chapter 11. This book is of benefit to theoretical study and new product development, which is written not only for engineer, faculty and graduate students in the field of noise and vibration control, signal processing and automatic control, but also for technician developing new acoustic products.
