Hello,
In regards to frog survey work...
Are there acoustic techniques which would allow one to map locations
of calling individuals within a given environment? Say with an array
of microphones elevated to give some geometric perspective above the
breeding area. It sure would be interesting to graphically be able
to see the group dynamics over a period of time, even days.
Individuals and species could probably be easily identified if the
spectral content could be represented. You would think some of the
experience gained from marine electronics could yield sort of "frog
finder". All of the DSP (digital signal processing) integrated
circuits on the market today sure do make for a lot of possibilities
for sound processing applications.
Any comments? Does this technology already exist?
