The sense of hearing is actually due to a response to mechanical stimuli; vibrations are converted into nerve impulses that the brain receives.
- Humans can hear sounds up to 20 kHz. The greater wax moth can hear sounds up to 300 kHz!
- The cilia in the ear push earwax out of the ear naturally.
- Snakes hear from their jawbones! No, really. Their inner ears are connected to their jawbones, so vibrations travel from the jawbones to the ear before being processed.
- One of the earliest known forms of body modification is ear piercing.
- Hearing and touch are the only senses that are types of mechanosensation.
- The human ear is made of three sections. The middle ear contains the smallest bones in the body, known as the ossicles (hammer, anvil, and stirrup).
- Crickets hear using organs called tympanum on their front legs.
