Abstract: Abstract The present paper focuses on two of the acoustic phenomena involved in sound propagation through forested areas, namely multiple scattering caused by tree trunks at mid-frequencies and ground effect at low frequencies. The use… read more here.

Abstract: A modified Biot/Squirt flow model was developed. The difference between MBISQ and BISQ models is the expression for the porosity differential. Numerical analysis shows that the acoustic dispersion predicted by MBISQ is much higher than… read more here.
