How do we hear/feel/see sound?

  1. Elliot's thoughts:

    Well,
    first we can feel sound when it's vibrating, for example a radio, when the radio is loud then you can feel it in the speakers.

    Everyone can hear sound except people who are deaf, although they can also hear with Cochlear Implants. Cochlear Implants are things that are on your ears. When you speak into it, it catches your speech and transports it straight to the brain through a cable. When the sound goes through the cable there's this piece of metal, not exacly heavy, called the coil, that trantsports the speech from the coil to the implant on the hearing nerve which then goes to the brain.

    When you turn on the radio it's actually the vibration that vibrates into our ear to our hearing nerve, our brain interprets it as sound.

    We can't see sound but we can feel it and hear it.
    Sound is something that you can't see because it is invisible.
    We can't see sound because it's the air vibrating and we can't see air.

  3. I learned that sound travels faster under water than thru the air. That is why the poor dolphins and whales suffer from the noise the ships make. Ava
