The Norwegian Defence Construction Service is carrying out a lagre scale experiment of noise propagation from explosions in a forest area. The scale of interest is 0-12 km. The project involves several research groups from different diciplines in Europe and the USA. Obviously the vegetation (trees, forest stands) is of importance for the propagation. I am utdated on the litterature up to about 1975, and I have got the understanding that simple forest stand attributes such as tree height, density (basal area), tree species, and volume are of great interest for propagation modeling. Do you know of any further research within this field during the last 20 years (references)? Due to the scale and the monetary budget limitations the project has to rely on aggregated forest stand attributes such as those mentioned earlier. "Micro"-studies are therefore not on the agenda.
