Abstract
A computer-generated simulation of sound propagation through six different types of leafy foliage has been carried out. To reduce the number of adjustable input variables, the simulation makes use of experimentally obtained leaf resonance parameters. In general, the resonance exhibits two groups of normal modes of vibrations in the audio frequency range. These modes have been attributed to the longitudinal and transverse vibrations of the leaf. Typical results of the simulation obtained are comparable to those determined experimentally in an anechoic chamber by Martens [J. Acoust. Soc. Am. 67, 66-72 (1980)].This publication has 2 references indexed in Scilit:
