Continuous automatic recordings of the directivity patterns at various frequencies have been obtained for loudspeakers and microphones placed in a reverberant enclosure. Tone bursts and electronic gating have been used to simulate free-field conditions. This method appears to give results as accurate as those obtained in an anechoic chamber. The lowest measurement frequency of the directivity pattern is determined by the size of the enclosure available.
