The book "Vibro-Acoustics, Volume 1" offers a comprehensive and detailed presentation of the theories of vibration and acoustics. It stands out from conventional textbooks by combining the two closely related fields of vibration and acoustics. The content includes fundamental analyses and mathematical descriptions of important vibro-acoustic phenomena relevant to noise reduction. This encompasses the study of how structures are excited, the energy flow from an excitation point to a sound-radiating surface, and the manner in which a structure radiates noise to the surrounding medium. The book contains numerous measurement results that make reading both informative and engaging. At the end of each chapter, problems and questions are listed, with solutions provided to promote a deeper understanding of the topics. This book is aimed at anyone interested in sound and vibration, vehicle acoustics, ship acoustics, and interior noise in aircraft.
