USING STATISTICS TO ANALYSE LISTENING TEST DATA: SOME SOURCES AND ADVICE FOR NON-STATISTICIANS
LE HARRIS, Keith Holland · 2023
Subjective listening tests are still an extremely useful way to assess the quality of audio reproduction equipment. It is now accepted that such tests can be regarded as scientific experiments if the test procedure and conditions are very carefully planned and controlled. Much has been published on this topic, and guidelines for carrying out rigorous tests can be found quite easily by those wanting to conduct their own. However, advice on how to analyse data from the experiments is less accessible within audio literature, despite this being a crucial part of the research process. Any careful preparation for the listening tests will be wasted if the results are poorly analysed and incorrect conclusions about the data are drawn.
