½-INCH INFRASOUND MICROPHONE, PREPOLARIZED
Infrasound microphone specifically designed for high-precision, acoustic measurements with high sensitivity in the frequency range of 0.02 Hz to 20 kHz.
TYPE 4964
Infrasound Microphone Cartridge Type 4964 is designed for high-precision, acoustic measurements where an infrasound microphone with high sensitivity is required. Being prepolarized, Type 4964 can be used with both CCLD and classical preamplifiers, and makes the microphone especially well-suited for battery operated equipment and operation in environments with high humidity.
