    Abstract

    The high-frequency performance of a p-p intensity probe with a solid spacer between the two microphones is examined. It is shown theoretically and verified experimentally that with a spacer length that equals the diameter of the microphones, the finite difference error is almost perfectly cancelled by a cavity resonance. It is concluded that the usable frequency range of sound intensity probes can be doubled with this configuration.
