Sound Source Locating Applications

As industrial equipment gets quieter, reduction of sound and countermeasures against noise are becoming very important. Here, we will introduce examples of applications of the sound source location.

•Sound Source Visualization using beam forming calculation method

Beam forming is one of the sound visualization techniques that calculates the distribution of sound pressure and sound intensity from the data recorded with microphone array system.

Automobile

This system helps to find sound source even though the sound source location is changed every moment according to the motion of power seat.

＜Noise exploration in a power window＞

When a power window is operated, rubbing noise is generated from the rail.

You can capture how the sound source location moves with color map and animation by this system.

Home electronics, Printer

＜Noise detection in air conditioners＞

Rattle noise of air conditioner and squeak of the frame can be visualized.

＜Operating sound of the desktop printer＞

Various noise are mixed behind the operation noise at the time of printing. This system allows to decompose the mixed noise to confirm which sound is generated from where.

System Configuration

•Sound Source Locating using octave analysis function

Automobile, Home electronics, etc.

The LA-7000 series, High performance Sound Level Meter can identify the sound source, too.

It is useful when you want to locate the sound source quickly and easily.
