Abstract:
    The utility model relates to an acoustic image measurer which is composed of measurement transducing mechanism and measurement analysis mechanism. Its feature is that the said measurement transducing mechanism includes surface reflector and microphone units which are set on the imaging focus of the surface reflector. The said measurement analysis mechanism includes ADC data acquisition card and computer. The input terminal of the ADC data acquisition card is connected with the every microphone signal in the microphone unit and the output terminal is connected with the computer. The utility model can conduct non contact type measurement when it leaves the real position of sounding object. The measurement analysis work is high efficiency and the result is accurate, especially fit to research work of distant range and fine measurable noise source.
