Episode notes
Hertz Defines Our Hearing Range
- Sound frequency is measured in hertz, indicating wave repetitions per second.
- Humans hear between 20 Hz and 20,000 Hz, which defines the podcast's name, "Twenty Thousand Hertz."
Animals Hear Different Frequencies
- Different animals hear different frequency ranges; dogs hear up to 40,000 Hz while elephants hear lower frequencies.
- Low frequencies travel farther through mediums like water, aiding long-distance animal communication.
Low Frequencies Travel Farther
- Low frequency sounds travel farther because of their longer wavelengths and less energy loss.
- High frequencies get absorbed or muffled more easily, explaining why bass passes through walls more than treble.
