AB  - The field-type acoustic wattmeter consists of a pressure microphone responding to the sound pressure, a velocity microphone responding to the particle velocity, and an electronic system for combining the voltage outputs of the microphones so the ultimate output indicates acoustic energy flow in a sound field. The field-type acoustic wattmeter may be used to measure, for example, the sound output of loudspeakers, the noise output of machines, the sound absorption of walls, ceiling and floor of an enclosure, and the acoustic performance of sound-reproducing systems in rooms.
