Target audience is professionals (acoustical consultants, architects, mechanical engineers) and enthusiasts (home theater, home studio) who are looking for tools to do calculations or designs of acoustical environments. This is to be a rebranding of threedb.com. See http://threedb.com/rt.php for an example web app this logo would appear on. (CSS was by a 99designer!)
PLEASE READ MY PUBLIC COMMENTS
With this name there is a collaborative element, sharing of information with the community.
Unless you think you can break the mold, avoid the cliches of our industry: sine waves and propagation (like the RSS icon). Think of a fresh take on the icon, maybe as it relates to architecture and/or engineering.
Font should work well with a ".com" and ".org" after it, maybe in a gray.
