NASA in full National Aeronautics and Space Administration Independent U.S. , they're actually working on something that is no less sophisticated, in some regards, though it may seem to be: they're analyzing the sound from a model of a Chrysler Group Stow 'n Go minivan seat tub. They're inside the Sound Transmission Loss Suite in the recently opened Noise and Vibration Application Research Center, a 65,000-f[t.sup.2] facility opened in Canton, MI, by Materials Sciences Corp. (MSC (1) (MSC.Software Corporation, Santa Ana, CA, www.mscsoftware.com) Founded in 1963 by Richard H. MacNeal and Robert G.

What appears to be something out of Close Encounters of the Third Kind is actually a cluster of microphones and instruments. Below the floor of the hemianechoic room there is a reverberation chamber; sound is generated through the seat tub, then measured by the instruments. |
