Implementation of an integrated virtual instruments environment for acoustic measurements Host Publication: Proceedings of the International Seminar on Modal Analysis, ISMA 2002 Authors: A. Touhafi Publication Year: 2002
Abstract: This paper presents a virtual acoustic measurement instrument, which allows the user to define a variety of acoustic measurement systems without the need to have a deep knowledge in programming. The virtual acoustic measurement instrument consists of a modular hardware part and a generic software part. The hardware part is made low-cost by using a PC and professional soundcard as base for signal processing and data-acquisition. Additional signal conditioning hardware is implemented to broaden the possibilities of the instrument. The most effort is put in the software, which has two main parts that are a graphical user interface and an emulation
engine. The graphical user interface allows the user to define his virtual instrument and the emulation engine, emulates the defined acoustic measure instrument in real-time.
