Motorola make a range of relatively cheap sensors to measure acceleration, pressure and temperature. Motorola are part of the ZigBee consortium that is an alliance of companies that have developed low-power wireless protocols and products. See Motorola’s product range here. They also sell evaluation boards which can be found on their web site.
Eurocopter EC255 has an active vibration control system
Eurocopter’s latest development the EC225 joins their Super Puma family of helicopters. The new helicopter has lower cabin noise than the Super Pumas by about 3dB. In addition, an active vibration control system reduces vibration levels to about 0.08g.

NASA are listening for aircraft wake
NASA Langley Research Center are conducting experiments at Denver International Airport to measure the sound generated by the vortex wake of aircraft. In addition two LIDARs (laser radars) will be used to measure the vortex strength and movement. The scientists hope to determine whether a permanent monitoring system is feasable at an operating airport.
