Chris Slade commented that researchers differ on which sounds bees make
before swarming.
Eddie Woods used a specific frequency of sound, and he had a good ear, so
his device apparently worked.
The problem is/has been that investigators assume they can 'pick' the
sounds. Sound is multi-dimensional, its not just frequency. Amplitude,
frequency shifts, timing, etc. are parts of sound.
The investigator based approach has the same problems as the earlier
programmers trying to produce software that recognizes speech, or that generates
speech. Each of us produces sounds in slightly different ways, even when
repeating the same word.
Yet, modern technologies now offer speech recognition that is pretty good -
whether its your phone dialing the number of someone, or the electronic
telephone information for city, state.
Like many of these programs, we don't pre-suppose that we know enough to
'pick' sounds. We have developed and patented the use of pattern
recognizing software programs that take advantage of multiple aspects of sound.
