Animals Use Frequencies Beyond Our Hearing
- Rudy explains animals like elephants use infrasound via feet to communicate across miles at 3–8 Hz.
- Dolphins can perceive up to ~150,000 Hz, showing species-specific frequency windows.
Human Senses Show A Narrow Slice
- Rudy ties hearing bias to the visible light analogy: humans sense a tiny slice of the full electromagnetic and acoustic spectra.
- Machines extend perception, revealing ultraviolet, infrared and many inaudible frequencies.
Analog vs Digital Sampling Limits
- Jason contrasts analog tape's continuous capture with digital sampling and bit-depth limits.
- He argues higher sample rates (96kHz) retain harmonics above human hearing and subjectively sound better.
