Method for automatically measuring and testing sound field of complete anechoic chamber and standard device

The invention relates to a method for automatically measuring and testing a sound field of a complete anechoic chamber and a standard device. A traditional manual sound field measuring and testing method is low in measuring efficiency and poor in measuring accuracy. The standard device comprises a signal generator, a power amplifier, a sound source, a standard microphone, a microphone fixture, a signal collecting and analyzing system, a traction fish wire, a fixed steel wire, a pulley, a traction wire rotating wheel, a telescopic rod, an H-shaped piece, and a mainframe box. The signal generator sends out sound signals through the sound source after going through the power amplifier. The sound signals are received by the standard microphone and then are processed and analyzed. The standard microphone automatically walks in a preset path. The method and the standard device enable measuring data of the sound field of the complete anechoic chamber to be more accurate, more credible and more authorized.
