Sep 12, 2022 · On the atomic scale, sound is a disturbance of atoms that is far more ordered than their thermal motions. In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects (Figure \(\PageIndex{2}\)).
Sep 12, 2023 · In this post, we’ve taken a comprehensive look at sound waves, starting with the basics of what type of wave sound is—a longitudinal wave. We discussed its key aspects like frequency, amplitude, and speed in various media, breaking down how these properties shape our auditory experiences.

Models Describing Sound. Sound can be modeled as a pressure wave by considering the change in pressure from average pressure, ΔP = ΔPmaxsin(kx ∓ ωt + ϕ). Δ P = Δ P max sin ( k x ∓ ω t + ϕ). 17.1. This equation is similar to the periodic wave equations seen in Waves, where ΔP Δ P is the change in pressure, ΔPmax Δ P max is the ...

Jan 15, 2019 · Waves are most commonly described by variations in some parameter through space and time—height in a water wave, pressure in a sound wave, or the electromagnetic field in a light wave. The value of this parameter is called the amplitude of the wave; the wave itself is a function specifying the amplitude at each point.
The physical phenomenon of sound is defined to be a disturbance of matter that is transmitted from its source outward. Sound is a wave. On the atomic scale, it is a disturbance of atoms that is far more ordered than their thermal motions. In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion.
