Incoherent source sound addition
WebDec 10, 2007 · The sound intensity level at a certain point in the concert hall is 32.0 dB. What is the sound intensity level at the same point if only one of the violinists plays the same passage? ... Look up the equation for sound pressure addition for incoherent sources. The total pressure is the sum of the squares of the individual sources. WebInterference is the addition, in the mathematical sense, of wave functions. A single wave can interfere with itself, but this is still an addition of two waves (see Young's slits experiment ). Constructive or destructive interference …

WebJun 1, 2001 · However, in addition to the physical sources that are of interest, the measurement system, data acquisition and signal processing also introduce additional artificial incoherent noise sources. WebApr 1, 2024 · The POD method is used to decompose the sound field in the frequency domain. It helps to establish the relationship between coherent structures of sound field and locally coherent noise sources. In addition, the method can also be used to eliminate the influence of background noise by selecting POD modes with higher energy.
