'Moving source' software for data analysis

Brüel & Kjær has developed a 'Moving Source Option', which is claimed to make performing noise source identification on moving vehicles a much easier process.

 

Unlike traditional Beamforming kits, the Moving Source software follows a mobile target, instead of focusing on a single point. It tracks linear movement parallel to a planar microphone array and enables speed-position calculation from a radar signal, GPS or photocells.

 

Beamforming is a method of mapping noise sources using an acoustical array. It discerns the direction from which a sound originates, by means of the time delays that occur as the sound passes over an array of microphones.

 

This method is very quick, allowing a full map to be calculated from a single-shot measurement, making it ideal for noise source location of sound radiated from moving vehicles such as cars, lorries and trains. Moving Source Beamforming can also be used as a troubleshooting contribution during pass-by measurements and mapping planes from the side of a vehicle.

 

Brüel & Kjær’s PULSE hardware provides a stable and continually evolving data analysis system, which allows users to add upgrades, rather than switching to an entirely new system, as software is developed.
