A microphone traverse system (microphone positioning system) is now one of the essential tools for acoustic measurement. Understanding sound source means to obtain important information to implement countermeasure against sound power level or the measuring against the source of noise. Our company has developed an automatic measuring system using robots. We provide broad services from its design to set up to maintenance. Our Mechatronics technology has managed to reduce labor hours for measuring on the spot by automating the troublesome measuring point positioning of a microphone. We have continued to produce great variety of products up to the present time.
