Abstract

A measurement system is presented that allows large apertur e measurements with a high angular resolution and that is still co mpact and thus convenient for portable use. Theoretical cons iderations show that a cardioid microphone characteristic is de sireable to achieve a low amplification of sensor noise throughou t the audio frequency range. The directivity of real cardioid microphones, however, deviates from the ideal cardioid pattern. Here, it is demonstrated how the use of one omnidirectional and one figure-of-eight microphone offers the possibility to optim ize the directivity pattern of a virtual cardioid microphone throu gh suitably designed compensation filters.
