Before jumping into the project, it is only fair to know basically how do humans hear and feel.
When we hear a sound, this is what actually takes place:
- Sound waves enter the ear canal and cause the eardrum to vibrate.
- Vibrations pass through 3 connected bones in the middle ear
- This motion sets fluid moving in the inner ear.
- Moving fluid bends thousands of delicate hair-like cells which convert the vibrations into nerve impulses.
- Nerve impulses are carried to the brain by the auditory nerve
- In the brain, these impulses are converted into what we “hear” as sound.

Your somatic sensory system is responsible for your sense of touch. The somatic sensory system has nerve receptors that help you feel when something comes into contact with your skin, such as when a person brushes up against you. These sensory receptors are generally known as touch receptors or pressure receptors. You also have nerve receptors that feel pain and temperature changes such as hot and cold.
Q: Whats the similarity between frogs and us?!
A: Both frogs and human have the same organ parts! We both have eyes that can see underwater. We both also have vocal chords and also many other organs which have similar purposes.
One thought on “Sound & Touch : Research”
Thanks for the research headstart!! Hmmm…as for the quiZz, not quite the answer I was looking for… Let’s wait a little to see what the others have to offer.. 😉
