For situations where concurrent measurements are required at several points in an array. For example in the analysis of sound fields, sound power and transients. Close manufacturing tolerances together with the advantages of the TEDS chip provide these array microphones with a high degree of interchangeability; a major advantage when used in multiples forming arrays and matrices.
