  • Title: Generating sensor signals in isotropic noise fields.
    Author: Habets EA, Gannot S.
    Journal: J Acoust Soc Am; 2007 Dec; 122(6):3464-70. PubMed ID: 18247755.
    Abstract:
    Researchers in the signal processing community often require sensor signals that result from a spherically or cylindrically isotropic noise field for simulation purposes. Although it has been shown that these signals can be generated using a number of uncorrelated noise sources that are uniformly spaced on a sphere or cylinder, this method is seldom used in practice. In this paper algorithms that generate sensor signals of an arbitrary one- and three-dimensional array that result from a spherically or cylindrically isotropic noise field are developed. Furthermore, the influence of the number of noise sources on the accuracy of the generated sensor signals is investigated.
