uire accurate computations of sound propagation in theatmosphere. This book describes models that can be used for thesecomputations. The models take into account complex effects of theatmosphere and the ground surface on sound waves, including theeffects of wind and temperature distributions, atmosp

Commonplace

Noise barriers, propagation over a vertical screen. In Appendix 0 we describe the computational methods in more detail. Experimental results for sound propagation over barriers can be found in Refs. [114], [71], [38], [117], [12].

ADAGE

Unbounded homogeneous atmosphere,he average pressure, . the variation of the pressure, is called the . or the .. A sound wave travels with a finite speed of about 340 m/s. This is experienced most clearly for sound pulses: it takes some time before a sound pulse generated by a source reaches a distant receiver.

vitreous-humor

Introduction,. Sound waves are generated by a source and travel through the atmosphere to a receiver The source may be a whistling bird, as in Fig. 1.1. Other important example: of sources are cars, trains, and airplanes.

cutlery

Atmospheric refraction,ing atmosphere is justified only for small propagation distances. For propagation distances of the order of 100 m or more, atmospheric refraction often has large effects on received sound pressure levels, in particular if the source and the receiver are close to the ground, at heights of a few meters or less.

macular-edema

Atmospheric turbulence,d the (effective) sound speed we used smooth functions of height [see Eqs. (4.5), (4.12), (4.13), and (4.14); see also Appendix N]. These profiles should be considered as average profiles, averaged over a period of typically ten minutes.
