Using of Industrial Multifunction I/O Cards for Electroacoustical Measurements
This paper deals with using of industrial multifunction cards for electroacoustical measurements controlled by a personal computer. The advantage of these cards lies in their low price in comparison with profes-sional systems for the electroacoustical measurements. A simple computer-controlled measurement system with the sufficient accuracy for basic electroacousti-cal measurements can be established easily with the help of simple external analogue devices and dedicated software. The paper deals with an algorithm for measurement of frequency and directional responses of mi-crophones and speakers and with realization of the algorithm using application program-ming interface of the ActiveDAQ Pro library.
