• Comparison Between Sound Intensity Probes and Acoustic Cameras
  . These two devices are performing similar, but different tasks. With this information in mind, an acoustic camera has advantages when evaluating both steadystate and non-steadystate phenomena. It can also provide results quickly. However, acoustic cameras are limited in frequency range and are further...
• Acoustic Holography, Noise Source Identification and Quantification
  source(s) that contribute to the overall problem. Product characterizations often involve not only the measurement of sound pressure and sound power, but also vibrational velocities of radiating surfaces and energy flow information, such as acoustic intensity vector maps, in order to locate...
• Cosworth Technology & Arup Reduce Engine Acoustic Analysis Time
  calculated engine sound power levels for all combinations of speeds from 1,500 to 6,750 rpm and frequencies from 100 to 2,500 Hertz for a new 3-litre engine design. The result of having detailed acoustic information early in the design process makes it possible to optimize the design of the external...
• Acoustic Target Setting Supports BMW's Premium Brand Image
  Construction Recognizing that acoustics define the character of an automobile, BMW is driving business forward with acoustic target setting and hybrid simulation to engineer the sound of its vehicles. Using state-of-the art technology and processes, they combine test data on existing components...
• Accelerating Structural and Vibro-Acoustic Simulation Through Wave Based Substructuring
  Built on top of the LMS Virtual.Lab Structures solutions for component, subsystem and full vehicle modeling, analysis, and post-processing, LMS Virtual.Lab Wave Based Substructuring (WBS) brings innovative technology for fast structural and vibro-acoustic modification predictions and vehicle...

• Boeing Uses LMS SYSNOISE to Predict Acoustics of Aircraft Cabins
  Boeing uses acoustic models coupled to structural methods to predict low-frequency noise caused by engine vibration and other sources. Jim Johnescu, Senior Specialist Engineer for Boeing Commercial Airplane, has used test-based methods to accurately determine the boundary conditions...
• Boundary Element Acoustics
  a solution and the use of pre- and post-processing to manage the information obtained from each method. In some sense, however, the FEM is the more general of the two methods. The FEM may be used for non-linear problems such as when the sound pressure is extremely high or when the acoustic domain...
• Alenia Spazio Optimizes Noise & Vibration Performance of Space Systems
  Alenia Spazio defined and developed an integrated test/simulation process, which allows meeting the tightest micro-gravity and vibro-acoustic requirements inside manned space vehicles. Once in space, on-board conditioning and electric power systems induce noise and vibration levels that potentially...
