In today's hectic world of traffic jams and
congested city streets, any reduction in stress-generating noise
is a welcome contribution in the quest to improve our urban environment.
While much of the noise made by cars and other automobiles is generated
by their engines, a myriad of other rattles, hums and clickety-clacks
come down to loose body parts and poorly designed interior panels
This project was aimed at developing a new laboratory
testing system using laser interferometry to detect and localise
noisy elements in automobile parts and other machinery. The system
delivers a holographic representation of the vibrational pattern
of a sample, allowing noisy elements to be redesigned or eliminated.
The new system has now been successfully
launched on the market and a cumulated turnover of over 2.5 million
euro has been achieved. The prime partner is now the only European
supplier of such a system. The two other project partners, PSA and
Mercedes Benz, have become pilot customers.
