Musician and natural soundscape expert Bernie Krause describes how a healthy environment has animals and insects taking up low, medium and high-frequency bands, in exactly the same way as a symphony does.
Glazbenik i stručnjak za zvučnu pozadinu Bernie Krause opisuje kako zdravo okružje ima životinje i kukce koji imaju nisko, srednje i  visoko frekventni raspon, na isti način kao što to čini simfonija.
