Omschrijving
Elements of aviation acoustics
Quieting cabin and flight deck noise, and reducing the impact of noise on
commununities near airports are matters of great importance to
air-manufacturers and airline operators for already more than four decades.
Undoubtedly, knowledge of both aeronautics and acoustics is essential for
a clear understanding of any aviation noise problem. Such understandmg is
a necessary prerequisite to the control of interior and exterior noise.
In view of the importance of education in dealing with noise control, this
book is devoted to the branch of aerospace engineering known as aviation
acoustics. The book contains twelve chapters and three appendixes which
originate from an annual course on airplane noise given by the author to
aerospace engineering students at Delft University of Technology (DUI).
The book is intended to be useful to undergraduate students of aerospace
engineering, and also to researchers and practicing engineers who wish to
revive their understanding of the topic.
The text assumes litde or no previous knowledge of acoustics.
