This book presents the proceedings of the 46th National Symposium on Acoustics (NSA 2017). The main goal of this symposium is to discuss key opportunities and challenges in acoustics, especially as applied to engineering problems. The book covers topics ranging from hydro-acoustics, environmental acoustics, bio-acoustics to musical acoustics, electro-acoustics and sound perception. The contents of this volume will prove useful to researchers and practicing engineers working on acoustics problems.
List of contents
Introduction.- Condition Monitoring.- Physical Acoustics and Ultrasonics.- Aero Acoustics.- Acoustic Materials.- Speech.- Acoustic Vibration and Noise.- Under water Acoustics.
