    Acoustic Fundamentals And The Nature Of Sound

    Why should one bother trying to understand basic acoustics? The most simple (and correct) answer is that study of basic concepts enables one to sort through the truth, semi-truth, myths and flat-out errors that pervade the pro audio industry. The fundamentals of acoustics (and physics) do not change, although some “experts” try to prove otherwise. New equipment, toys and theories come and go, but the basic building blocks of sound and its related concepts do not. If university level training… View this story

    Sound Wave Propagation: The Bigger Picture Of What We Hear
    sound science
    Neil Thompson Shade 04/11/12 09:14 AM,
    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
