Abstract
Electronic test instrumentation for acoustics and vibration measurement has seen radical changes during the final decade of the 20th century. From analog to digital to PC based, the performance, flexibility and ease of use have risen while the price per performance has declined. Taking advantage of the rapid developments in PC operating systems, mass marketed microprocessors, and the professional audio industry, todays instrumentation frequently has more in common with both the recording studio and the home computer than with the physics laboratory. The future promises even more as this evolution continues. Two examples, vehicle vibration analysis and electroacoustic testing, are used as examples to follow the development of test platforms. The advantages (and disadvantages) of software-based testing are discussed, and some insights of what the new decade might offer are provided.
