• Comparison Between Sound Intensity Probes and Acoustic Cameras
  limited to only providing information about sound pressure levels. The microphone array based solution has the same advantages and disadvantages as an acoustic camera, but often at a fraction of the cost. A sound intensity measurement is a direct measurement, without the approximation and resolution...
• Building a Robust Path for Virtual Wind Turbine Design
  measurement signals - to acquire deflection, vibration and acoustic responses in, on and around the wind turbine." Members of the crew used the LMS Test.Lab software suite to control synchronous data acquisition, and to perform any data analysis action they required. An extra measurement system, equipped...
• Versatile and Rugged Data Acquisition for NVH
  format. PAK Mobile MK II ­ the state-of-. the-art frontend for the PAK. measurement system. It is user-. configurable for any acoustic. and vibration measurement task. and best in class for compact-. ness, performance and reliability. Execute simultaneous time-. signal recording with nearly no. limits...
• Do You Need To Measure Brake Noise?
  Hamsand Posted July 19, 2011 at 11:15 AM. Measurement on the brakes are often done by using "conventional" FFT. A very frequent question is why the peaks change when the block size is changed. The answer is relatively easy considering that the vibration signal from the brake caliper is very noise like. My...

  holes. A high-speed stage, fast wafer handling, and accurate measurement algorithms ensure high throughput. The Gencobot 9 servo-controlled robot offers repeatable indexing and transfer of wafers and flat-panel displays in vacuum processes >=10 8 torr. The robot's global positioning system ensures...
• Combination of Sensing Techniques Checks Laser Weld Quality
  different shortcomings, such as noise or errors that corrupt the signals and make them inexact. The idea is that the three different sensors are corrupted by noise and errors in different ways, he said. So by putting those multiple measurements together we get a better measurement of the information we...
• Audi Implements LMS Test.Lab for Higher Productivity in NVH Testing
  laboratories and the technology development centers in Ingolstadt and Neckarsulm. The choice of LMS Test.Lab is largely driven by its tight integration of all data acquisition, analysis and reporting tasks, and the complete coverage of structural, acoustic, and rotating machinery testing processes...
