Anyone know who really invented the "Sound-beam" ? - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi,

todays headline news contains a link "Sound-Beam Inventor Wins $500,000 Lemelson-MIT Award" http://www.msnbc.msn.com/id/7536267, saying that a lonesome guy invented the "sound-beam". But Sennheiser http://www.sennheiser.com/sennheiser/icm_eng.nsf/root/09859 already offers something like that since 2000, so who was the first ? Or maybe both invented it at the same time ?
