Nonlinear effects in the propagation and measurement of blast noise

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

It is well known that nonlinearity affects the propagation of blasts. For example, the high levels of blast noise lead to nonlinear steepening. Mach stem formation and harmonic generation leading to an enhanced high frequency content are other established phenomena. However, other nonlinear aspects of blast wave propagation, such as pressure amplification on a microphone diaphragm are less well known. Other commonly overlooked effects include nonlinear wave interaction with finite impedance grounds and the influence of nonlinearity on blast rise times. The goal of this paper is to elucidate some of these lesser known nonlinear effects. In addition some suggestions are made for future field tests that will help to clarify the role of these nonlinear propagation phenomena.
