In fact, the wavelengths of sound that humans can hear are between 20 meters and 2 cm and the frequencies of electromagnetic radiation at those same frequencies are 20 MHz to 20 GHz, right in the radio/microwave regions. Of course, sound covers that whole bandwidth at once, while radio transmissions are quite narrowband. There's a lot of research going on at the moment on <a href="http://en.wikipedia.org/wiki/MIMO" rel="nofollow"> multiple input, multiple output</a> communication systems, like 802.11n, that are designed to handle such situations. I haven't looked into it that closely, but it seems like that research mostly focuses on coding the transmission or beamforming at the transmitter or receiver, which are less interesting to me. I think it would be cool to make a radio that could hear radio waves like humans hear sound waves, removing echoes, separating overlapping sources, etc. Such a technology might substantially increase data rates.

It works wonderfully on my site. I really want to use the vertically-tileable one somewhere as well, but I haven't found a place (yet). This is really well done.

The important thing for me is that they locate the crickets by listening and do so extremely well. I stand corrected.

From what I have studied, the flies don't dive bomb the cricket and spray it with eggs. They fly in close, then sneak up on the cricket, then lay their larvae (not eggs) on the cricket which then penetrate the cricket. The larvae then consume the cricket from the inside-out. In around 10 days they leave, killing the cricket. I think you may be mistaken about something. From what I have studied, the flies don’t dive bomb the cricket and spray it with eggs.
