Unlike porous models developed for particular absorbing materials and frequency ranges, the Johnson-Champoux-Allard model is a generalized model for sound propagation in porous materials over a wide range of frequencies. This model is nowadays used widely across the acoustic research…

Observed psychoacoustic events are often incompatible with musical knowledge. The point has been made particularly in the realm of pitch theory. This paper will contend that it is not the case that musical knowledge does not apply to psychophysical tasks…

There has been comparatively little study of train noise acceptability. This paper reviews state-of-the-art knowledge on the subject, and suggests criteria in terms of Leq.

In problems of sound propagation outdoors it is usually assumed that the ground is infinitely hard, and that sound from a point source spreads in the space above the ground according to the inverse square law. At large distances molecular…
