Now that we know how the ear works, we can suggest an explanation for this phenomenon. When we listen to loud music, all the compressors in the ear swing into action, including tensor tympani and stapedian muscles. The tensor tympani tightens the eardrum, and the stapedian muscle stiffens the ossicles. All sheet metal specifications can be re-used by the Knowledge Advisor workbench to capture corporate knowledge and increase the quality of designs. Natively integrated, Generative Sheetmetal Design offers the same ease of use and user interface consistency as all V5 applications.

For almost 20 years, advanced techniques have been developed and tested at the GEO 600 laser-interferometric gravitational wave detector. Many of these innovations have improved the sensitivity of GEO 600 and could be shown to be consistent with stable and reliable operation of gravitational wave detectors. The resonance increases vibration level on the tractor and structure borne noise is generated from the sheet metal components, which is contributing to overall noise levels. The Vibration reduction methodologies like stiffening the structure, isolating the source from excitation and dampening techniques were studied.
