he PCB 130 series of Array Microphones are prepolarized, condenser microphones coupled with ICP sensor powered preamplifiers and are thus referred to as ICP microphones. This eliminates the need to purchase a separate preamplifier. The 130 series microphones provide an extremely cost-effective method for large channel count sound pressure measurements. Typical applications include sound pressure mapping, acoustic mode analysis, near-field acoustic holography, and vibro-acoustic testing, along with other applications.
