    Sound Wave Propagation: The Bigger Picture Of What We Hear
    sound science

    Previously (here and here), we’ve been looking at sound on a “microscopic” level, examining particle motion as sound propagates through air. This time, let’s look at a larger picture of sound wave propagation. A vibrating object will disturb the surrounding air medium causing localized changes in pressure and particle displacement with the transference of acoustical energy in the form of a sound wave. Waves can be broadly classified as being either transverse or longitudinal. The distinction for each wave type… View this story

    The Scientific Essence Of Sound: Getting To The Basis Of Everything We Hear

    If you made it through the first installment of this series, give yourself a high-five. Better yet, bring those two hands together to create an impulsive sound with a propagating omnidirectional wavefront! This time, we’ll have a look sound particles, acoustic pressure, propagation medium density, particle velocity, acoustic energy, volume velocity, and acoustic impedance. Abstract concepts? Nope - far from it. All are related to the physics of sound propagation in an elastic medium that result in changes to the… View this story
