What microphone is recommended for determining the direction or noise source location of sound?

Multiple free-field microphones spaced in a predetermined pattern and combined with the appropriate software; allow spatial transformation of a complex sound pressure field to be projected to effectively map the acoustic energy flow. Array microphones are an excellent choice for large channel count acoustic testing due to their overall value and phase matching specifications. Transducer Electronic Data Sheet (TEDS) are recommended, since they enable the user to quickly and easily identify a particular microphone.
