To expand on what fatbrain wrote, you could get *much* better signal-to-noise ratio, probably eliminating the need to use your hand to focus the sound energy, as well as much more accuracy by using something only slightly more complicated than a simple click sound. While this would probably make it more complicated for a teacher to explain to his/her students (unless the students are studying digital signal processing), I think it would be a really cool addition. <br><br>I'd recommend looking into Golay Codes for their sheer simplicity and their robustness. <a href="http://cnx.org/content/m15947/latest/" rel="nofollow">http://cnx.org/content/m15947/latest/</a> has a basic tutorial.
