A sound intensity analyzing system consists of a probe and an analyzer. The probe simply measures the pressure at the two microphones. The analyzer does the necessary integration and calculations to find the sound intensity.
The sound intensity probe has a a face-to-face design. It consists of a robust frame that holds the microphone preamplifiers and matched microphones in a face-to-face configuration. The distance between the microphones is defined by a solid plastic spacer held in place by a threaded stud on the microphone grids. Sound is constrained to act on each microphone through a narrow slit between the spacer and the microphone grid. This arrangement gives well-defined acoustic separation of the microphones and minimizes shadow and reflection effects.
The probe is strong but lightweight and is connected to Type 2270 directly via a cable, or via an extension rod and handle with a cable. The probe kit includes an ellipsoidal windscreen.
