    Study Notes

    How We Hear Sound

    • Sound waves travel through the air and reach our outer ear.
    • The outer ear directs sound waves through the ear canal to the eardrum.
    • Vibrations from sound waves cause the eardrum to vibrate.
    • These vibrations travel through tiny bones in the middle ear and reach the inner ear.
    • A nerve carries the sound message to the brain, allowing us to hear.

    Reflection of Sound

    • An echo is a sound that bounces back from a solid object.
    • To hear an echo, minimal interference from other sounds is necessary.
    • Caves are good places to hear echoes due to their enclosed space.
    • Clothing absorbs sound waves, reducing echoes in spaces with people.

    Hearing and Feeling Vibrations

    • We can both hear and feel vibrations, like those from a passing train.
    • Our ears perceive vibrations as sound.
    • Deaf individuals can still feel vibrations in their bodies.

    Sound Vibrations and Materials

    • Vibrations travel through various materials, including air, water, plastic, metal, and wood.
    • Some materials transmit sound vibrations better than others.

    Energy and Sound: Properties of Sound

    • Sound, like voices, music, and traffic noise, is a form of movement energy.
    • Vibrating objects create sound waves that travel outwards.
    • Sound waves travel through solids, liquids, and gases.
    • The loudness of sound decreases with distance.
    • Decibels (dB) measure the energy in a sound wave.
