Abstract

PURPOSE:To facilitate operation in a simple structure by sequentially controlling the operation of a sweep generator, a detector, a recorder, and the like based on the status of operating switches. CONSTITUTION:In the measurement of the frequency characteristics, the operating switch S5 is connected to the side a, and a start switch S1 is depressed. Then a measuring signal SM is generated in the sweep generator SWG. A speaker SPK in an object to be measured X such as an auditorium generates a sound whose frequency exponentially increases with time. An output So of a microphone MIC is recorded in the recorder REC as a function of the frequency via the detector DEC. In the measurement of reverberation time, the switch 5 is connected to the side b, and the switch S1 is depressed. The sweep is temporarily stopped by the switch 2, and the switch S3 is depressed. When the desired frequency is attained, the sweep is stopped by the switch S4, and the reverberation time is measured. Therefore the structure is made simple and the operation is facilitated.
