Resumé

The aim of this study was to investigate the in uence of background noise location and stimulus type as factors contributing to the discrepancy in directional preference between the laboratory and real-world. The task used for this purpose was very similar to that employed with patients – indicating a subjective preference in a paired-comparison format. The main ndings were: (1) directionality is preferred when the signal is located at 0° azimuth, (2) asymmetrical directional setting is not undesirable in an asymmetrical noise eld, and (3) there is no signi cant difference in subjective microphone preference in a simulated real-world environment.
