Array microphones
Array microphones are designed to be mounted on large or small arrays, for example for the analysis of sound fields, sound power and transients. Such systems are typically used for measuring and locating noise sources, and here the phase match is important to get good accuracy in the measurements. An important characteristic of array microphones are precisely that the microphones are phase-matched.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.
