Mr. Olive is/was a compatriot of Dr. Toole and has done quite a bit of research on acoustics.

He now has a blog. Most of the posts to date cover past research, but are worth a read if you have not read them before. It should be an interesting blog if he keeps it going.

Nice link. Thanks.

Very good Fred; I wasn't aware of it and I'll certainly add it to the list of favorite sites on my computer.
