[TED] Bernie Krause: The voice of the natural world

Here is an excellent talk regarding the soundscape or acoustic ecology research on TED.

The signature of soundscape can be divided by “geophony, biophony, and anthrophony” three kinds of components. Through the soundscape analysis, we can receive more information from the recording environment which may not revealed by our eyes. An good example of application is presented in this talk: the difference of acoustic environment before and after artificial interference. Such kind of acoustical analysis can play a key role in this kind of environmental research in the future, but people still need to find a better way to make audiences more easily to perceive the sound sources of acoustic recordings.
