Webchapter, we know that the sound heard at one point is the same as the sound heard at another, although they might not be heard at the same time. Figure 1.1 shows a snapshot of a wave radiating from some point, found by plotting pressure p(x) at some fixed time t. If we pick two points x1 and x2 and look at the sound at those two points p(t ... WebJul 9, 2024 · In the second volume of his Theory of Sound, Lord Rayleigh presents a method for determining mathematically the intensity of sound at very great distances from a rigid sphere, the source of sound being confined to a small area on its surface. Prof. G.W. Stewart has extended the work of Rayleigh and has calculated the relative sound intensities for …

Rayleigh: Acoustically Speaking It is an indication of the vast range and scope of the scientific work produced by John William Strutt, 3rd Baron Rayleigh (1842–1919) that his foundational work on vibrations and sound doesn't figure in any way in the official citation which accompanied his Nobel Prize in Physics in 1904, awarded ". . . for his investigations …
WebRayleigh combined experimental work with theory in a very skillful way. Needing a way to determine the intensity of a sound source, he noted that a light disk suspended in a beam of sound tended to line up with its plane perpendicular to the direction of the fluid motion.
