The Effects of Recording and Playback Methods in Virtual Listening Tests

To better control confounding variables found in many listening test, researchers often use virtual listening tests, an accepted method in psychoacoustic research. A virtual listening test method can insure that listening conditions are the same for every test subject, but the choices of recording and playback methods now play an important role. In this report, the results of live and virtual listening tests with four different loudspeakers were compared. The analyses on listeners’ reliability, dispersion of data, preference rating, and Least Significant Difference (LSD) comparison results are presented. The experimental evidence showed the significant effects of recording and playback methods in the virtual listening tests. These results provide evidence that there are significant effects of recording and playback methods in virtual listening tests. A reliable and authentic evaluation can be obtained from virtual listening tests more easily and efficiently by the comprehensive consideration and selection of recording and playback methods.
