Abstract:

A sonic waveguide arrangement for use in transmitting sonic energy from one point to another along a non-linear path is disclosed herein and utilizes at least two different waveguides. One which is linear or straight in configuration and one which is curved. The first of these two waveguides is of a type which can transmit sonic energy over a relatively long linear or straight line path with relatively low transmission losses and the second is of the type which can transmit sonic energy over a relatively short curved path with relatively low transmission losses.
