From the reviews: Graduate students and professionals who are new to the field of active control are often faced with the fact that they need a working knowledge of several fields, such as microelectronics and digital signal processing, in addition to being well versed in acoustics and noise control. This book certainly fills the need of such readers and assumes no background in any of the fields mentioned above...Furthermore the author has narrated these with considerable wit, making the reading rather pleasurable. Overall, I would recommend this book readily for any serious student embarking on research in the area of active control. --Measurement Science and Technology "The author gives an overview of acoustics, noise control, and application areas where active noise control is applicable. ... It is also worth mentioning that this book definitely has a sense of humor ... . The author has done a very good job of providing simple explanations for many of the features ... . This text has the virtue of living up to its title of being a primer. ... the author provides some very good descriptions that should lead to understanding for the uninitiated." (Scott D. Sommerfeldt, Noise Control Engineering Journal, Vol. 53 (5), 2005) "Acoustic noise is a real problem in many environments ... . the book is designed for engineering students who want to acquire some background in this field without going into mathematical detail, hence the word 'Primer' in the title. ... The approach is practical and the level ideal for physics or engineering students, at advanced undergraduate or beginning graduate level ... . It is also the sort of book that lecturers and practitioners in related fields could read with profit. I recommend it strongly." (Neville Fletcher, The Physicist, Vol. 38 (3), 2001)
