> news announcements, we find that the sound level conveys

> price formation process and offer important implications for the
> future of open outcry and floor-based trading mechanisms.

but a warning - it's a 1.7MB pdf format file, so you'll need Acrobat
Reader to view it after it's downloaded. Oh, and it presents a great
deal of exceedingly detailed (arcane?) economic jargon, so beware!
