Covering a range of industries, LMS application cases let you discover how LMS solutions help our customers solve their real-life engineering challenges.
Engineers at International Automotive Components use the new LMS Test.Lab High Definition Acoustic Camera to identify noise sources in seconds
Engineers at International Automotive Components (IAC) – the largest acoustic materials supplier to the automotive industry – use the new LMS Test.Lab High Definition Acoustic Camera to identify noise sources in seconds compared to hours and days needed with traditional methods. Using this tool, engineers gain deeper insight into acoustic behavior and shorten turnaround times in lowering interior car noise for automakers around the world.
Vibro-acoustic testing on the high seas
CETENA Ship Research Center uses LMS Test.Lab for a variety of standard – and not so standard maritime equipment testing. Everything from worst case scenario shock tests to the acoustic resonant frequency of a Murano chandelier on a mega-cruise ship is subject to the expert scrutiny of the CETENA testing team in Genoa, Italy. And this team counts on the powerful LMS testing solutions that can deliver results in minutes instead of days as billion-euro projects hang in the balance.
LMS Acoustic Holography performs a spatial transformation of sound fields – meaning that it takes a measurement of sound pressures along a certain plane and predicts what the readings would be anywhere else. This can be towards the nominal source (back propagation), towards the far field, or in any other direction or plane. Special techniques are available when working in complex multisource environments. Acoustic Holography is a powerful tool that helps to solve noise source identification and quantification problems.
More on Acoustic Holography
Finding out the exact source of a sound is a tough challenge for any acoustics engineer. Since the early 90’s, a number of methods, based on microphone arrays, have matured and are used throughout numerous industries. In general, the methods fall into three categories: near-field acoustic holography, beamforming, and inverse methods. Depending on the test object, the nature of the sound and the actual environment, engineers will have to select one method or the other. What that means for the near-field acoustic holography (NAH) technique is described in more detail below
