A discussion is given of the correlation between the outputs of the two ends of a delay line, or between the corresponding outputs of two different delay lines, when a number of narrow-band noise sources, identical except that their outputs are all uncorrelated, are connected to points uniformly distributed along the delay lines. It is shown that when the total phase-shift in a delay line has a suitable value (e.g. ± Jt radians if the number of sources is large), the outputs at the two ends are quite uncorrelated, and that if the differences between the total phase-shifts of two delay lines has a suitable value (± JC radians as before, if the number of sources is large, but not the same as before if the number is small), then the outputs of the two lines are uncorrelated. The application of these results to the calculation of the noise factor of acoustic strip arrays is also discussed.

  • Acta Acustica united with Acustica, published together with the European Acoustics Association (EAA), is an international, peer-reviewed journal on acoustics. It publishes original articles on all subjects in the field of acoustics, such as general linear acoustics, nonlinear acoustics, macrosonics, flow acoustics, atmospheric sound, underwater sound, ultrasonics, physical acoustics, structural acoustics, noise control, active control, environmental noise, building acoustics, room acoustics, acoustic materials, acoustic signal processing, computational and numerical acoustics, hearing, audiology and psychoacoustics, speech, musical acoustics, electroacoustics, auditory quality of systems. It reports on original scientific research in acoustics and on engineering applications. The journal considers scientific papers, technical and applied papers, book reviews, short communications, doctoral thesis abstracts, etc. In irregular intervals also special issues and review articles are published.
