sound-wave

Definition
  1. Noun:
    • A wave of compression and rarefaction: "sound-wave" refers to a longitudinal wave that propagates through a medium (such as air, water, or solid) by compressing and rarefying the particles of that medium, and that is perceived by the ear as sound.
Usage Examples
  • Noun:
    • The loudspeaker converts electrical signals into sound-waves that travel through the air. (The device produces waves of pressure that carry sound.)
    • A sound-wave requires a medium to travel; it cannot propagate through a vacuum. (The wave needs material particles to transmit its energy.)
    • Scientists measure the frequency of a sound-wave to determine its pitch. (The number of compressions per second defines how high or low the sound is.)
Advanced Usage

  • "to be on the same sound-wave": to be in agreement or harmony (figurative, informal).

    • Their ideas were on the same sound-wave, so they collaborated easily. (Their thoughts resonated similarly.)

  • "sound-wave interference": when two or more sound-waves overlap, causing areas of amplification (constructive interference) or cancellation (destructive interference).

    • Noise-cancelling headphones use sound-wave interference to reduce ambient noise. (They generate opposing waves to cancel out unwanted sounds.)
Variants and Related Words
  • Soundwave (n): an alternative spelling (often used in technical contexts or brand names).
    • The oscilloscope displayed the soundwave pattern clearly. (The visual representation of the wave.)
  • Sound-waves (plural): multiple instances of the wave phenomenon.
    • The explosion produced powerful sound-waves that shook the building. (Multiple pressure waves.)
Synonyms
  • Acoustic wave: a wave of sound energy, especially in technical or scientific usage.
    • Acoustic waves travel at different speeds through different materials. (Equivalent to sound-wave in physics.)
  • Pressure wave: a wave that propagates by compressing the medium, often used for sound or shock waves.
    • The pressure wave from the thunderclap rattled the windows. (A type of sound-wave.)
Related Idioms
  • To ride a sound-wave: to take advantage of a trend or popular movement (figurative, informal).
    • The singer rode a sound-wave of popularity after her viral hit. (She capitalized on a sudden surge of public interest.)
