ANSYS have released version 7.1. Of particular interest to acoustic and vibration researchers are the improvements to the coupled field and modal analyses. Using the Mesh-based parallel Code Coupling Interface (MpCCI), you can now perform fluid-solid interaction analyses using ANSYS and a third-party CFD code, even if the meshes are dissimilar. The sparse solver and Block Lanczos eigensolver now support parallel processing for the Linux 32-bit platform, when using four to eight processors on this platform, you will improve the processing speed by a factor of 3 to 3.5 times that of a single processor.

Endevco have a 220 page book called, ‘The Handbook of Dynamic Force, Pressure, and Acceleration Measurement’, by Patrick L. Walter, from the Texas Christian University, that can be downloaded for free, upon registration.
Knowles Acoustics (formerly Emkay Innovative Products), a division of Knowles Electronics are now mass producing a surface mounted microphone called the SiSonic, that uses MEMS technology.
Note that Knowles also produce a small condenser microphone (2.5×2.5mm).
Researchers at the University of Illinois at Urbana-Champaign have developed a prototype brick that contains a thermistor, two-axis accelerometer, multiplexer, transmitter, antenna and battery. The brick could be used to monitor the ‘health’ of the building such as temperatures, or vibration.
