Although many measurements have been made of the propagation of sound over grassland, there are relatively few data over cultivated surfaces. The propagation of sound over an absorbing surface is in#uenced by the impedance of the surface and the locations of the source and the receiver. A reduction

## Results are presented of an investigation into the acoustical properties of a range of fibrous absorbent materials. Measured values of characteristic impedance and propagation coefficient are shown to normalise as a function of frequency divided by flow-resistance and can be represented by simple
## A BSTRA CT Measuring the shock spectrum of a mallet when it strikes a stationary force transducer is a convenient way to determine its effectiveness in exciting vibrations in a musical instrument. The maximum value of the residual shock spectrum, which indicates the frequency range over which a
Acoustical cross-sections of random homogenous dense systems of interacting and agglomerated Rayleigh particles are studied analytically. Both the interaction among particles within the agglomerate and the interaction among the agglomerates are taken into account. A model for the radial distribution
## ABSTRA CT The acoustic behaviour of fibrous materials which depends upon physical structural parameters has been investigated experimentally. Numerous values of characteristic impedance and propagation constant have been determined for materials having different fibre diameter and density. For
