"Though an unknown whistling sound occurs in a residential area, I cannot identify its sound source", "Unknown metallic clank is sometimes generated in my room", we accept inquiries for such problems which are called 'squeak and rattle' or 'unknown sound'.
When 'squeak and rattle' or 'unknown sound' which incurs a cost, this is when we use our Omni-directional sound source measurement system 'Noise Vision' to search and look for the location of the sound source. Noise Vision is an uncommon sphere. The surface of this sphere is equipped with 31 pieces built in microphones and 12 pieces built in CCD cameras with a peripheral circuitry that can bring in sound from all directions. You don't have to worry about having any misses because this device has a trigger function which is provided.
It doesn't take much time to prepare the measurement. Taking the measurement equipment out of the case and setting it up completely will take no more than ten minutes, and then you are ready to begin your measurement. After a few minutes of analyzing the generated noise problem the results can be displayed on the screen including the direction of where the noise is originated from. Because the direction of the unwanted noise is unknown, a key point is proposing to take effective measures to resolve this problem.
