Flying may become a more serene experience for those traveling on the new 737 NG Boeing Business Jet. Engineers have completed tests on a new active noise and vibration control system, supplied by the LORD Corp., which has provided engine isolators and mounts, hydraulic pump, and interior isolators for a variety of aircraft. Sound pressure levels dropped an average of 8 to 12 decibels for N1 engine tones. That's significant, especially when you consider that decibels are logarithms of sound levels. Now, if only someone could do something about those screaming babies.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
