    Study Notes

    Sound Waves Overview

    • Sound waves are characterized by two main properties: frequency (pitch) and amplitude (loudness).

    Frequency (Pitch)

    • Measured in hertz (Hz), representing the number of waves per second.
    • Average human hearing range: 20 Hz to 20,000 Hz.
    • Acute human hearing sensitivity is typically between 1,000 Hz and 3,000 Hz, where human ears are most responsive.

    Amplitude (Loudness)

    • Indicates the intensity of sound waves, measured in decibels (dB).
    • Average sounds in everyday life, such as conversational speech, measure around 60 dB.
    • Sounds at or above 80 dB can cause potential hearing damage.
    • Extremely loud environments, like rock concerts, can reach levels up to 120 dB.
