This paper describes a new time-dependent radiosity method (extended to specular reflection) that simulates the indoor propagation of a 60 GHz electromagnetic wave. The method requires two passes. During the first pass, the instantaneous radiosities

A new boundary-element method for predicting outdoor sound propagation over uneven ground is presented. This allows the sound field around complex boundaries (various absorptive properties and shapes) and in the presence of refraction to be calculate

The Gaussian beam approach solves the wave equation in the neighborhood of the conventional rays using the parabolic approximation. The solution associates with each ray a beam having a Gaussian amplitude profile normal to the ray. The approximate ov

This paper presents a set of acoustical and meteorological data from an outdoor sound propagation experiment. This experiment was done in a farm field near Rock Springs, Pennsylvania, on 7 July 1990. Meteorological and acoustical measurements were re

Results of experimental measurements of sound propagating over the range from 16 to 250 m at frequencies between 160 and 2000 Hz in a refracting atmosphere are described. Wind velocity and temperature are also measured simultaneously with the acousti

The computational tools available for prediction of sound propagation through the atmosphere have increased dramatically during the past decade. The numerical techniques include analytical solutions for selected index of refraction profiles, ray trac

In a complex outdoor environment, meteorological factors have been found to affect the sound field. On one hand, boundary element methods are particularly well adapted to calculate the sound pressure above complex boundaries (various absorbing proper

This paper compares the performance of a restricted number of barrier shapes and types under controlled experimental conditions and describes theoretical models. In particular, the attenuation of absorbent barriers on ground, of finite length barrier

To predict outdoor sound propagation through forests, multiple natural effects have to be taken into account such as ground effects and meteorology that vary along the path of propagation as well as horizontal trunk scattering effect. It is of great
