2.1: no thoughts just sirens

Listen Later

It’s season 2 baby! And to kick things off we’re going to ask and answer all the hearing-related questions you’ve never wanted to know the answers to. What has better hearing a frog or a parakeet? How does bat echolocation even work? If a tree falls in the forest, and nobody is around to hear it, does it listen to Indian kirwani music? Can my chicken hear me sing to her? Are ghosts real? As usual, things go off the rails, and you’ll have to suffer through several minutes of ASMR to find out the answers. Sorry about that. Get yer listening ears ready for this sonic journey into the science of hearing!


PSA: If you are like Kelsey and would rather eat a lightbulb than listen through the ASMR bit, it runs from 0:01:55 to 0:06:05 feel free to skip it, we understand. The transcript for that section is below so you don’t have to miss the fun facts.

The ASMR transcript — 

  • the intensity of a sound wave is measured in decibels. You can think of this as volume. 
  •  hertz on the other hand are used to measure the frequency of a sound wave, which is measured as the number of cycles per second. This is the pitch of the sound.
  •  So when we talk about an animal’s hearing range, we’re referring to the range of frequencies it’s capable of detecting.
  • The human (and most mammals) ear is made up of 4 parts
    • The outer ear
    • The middle ear
    • The inner ear
    • And the auditory nervous system
    • The outer ear is the flappy bit and the ear canal, its shaped weird to funnel as much sound in as possible
    • The middle ear is made up of two parts. the eardrum, also called the tympanic membrane transfers vibrations into your inner ear. On the other side of the eardrum is the ossicles, a set of three bones that pick up the vibrations transferred through the eardrum. The three bones are called the malleus, incus, and stapes and they're shaped really weird. 
    • The inner ear consist of the cochlea which means snail shell because thats exactly what it looks like. Theres tiny hairs inside the cochlea. The hairs transfer the sound vibrations to the auditory nerve which sends the information to your brain
