LMS enhances noise-test software
Staff- May 1, 2010
Revision 10A of LMS International's Test.Lab integrated software environment for noise and vibration testing performs time-domain TPA (transfer-path analysis) and MIMO RF testing and also offers new capabilities for acoustic testing.
Time-domain TPA complements Test.Lab's frequency-domain TPA and is useful for analyzing transient phenomena. MIMO RF testing extends the modal testing techniques of Test.Lab and allows users to specify their excitation signals, define a shaped amplitude spectrum, and extend the application to multisine excitation.
For engineers who perform acoustic tests, the software's Sound Quality measurement feature has been expanded with new psycho-acoustic metrics used in the automotive and aerospace sectors, while the Sound Intensity feature gained a 3-D acoustic mesh generator. The software provides an overview of all measured and processed data, quality indicators, and related components to help users analyze the data for sound power, source ranking, and sound source localization.
