Book Description
This book expresses the full understanding of Weyl's formula for the volume of a tube, its roots and its implications. Historical notes and Mathematica drawings have been added to this revised second edition. From the reviews: "Will do much to make Weyl's tube formula more accessible to modern readers.... A high point is the presentation of estimates for the volumes of tubes in ambient Riemannian manifolds whose curvature is bounded above or below." --BULLETIN OF THE AMS
Component Acoustic Testing Plane Wave Tube and Reverberant Chamber Methods

Pages : 82
Book Description
The design features and operating parameters of plane wave tube and reverberant chambers are described. Four different size plane wave tubes are used with a driving power of 200 audio watts to achieve sound pressure levels up to 154 db between 300 and 7500 cps. Two reverberant chambers are described and their performance evaluated. A comparison is made of the merits of plane wave sound fields and reverberant sound fields for testing purposes.
