The rapid growth in the number of 2-channel and 5.1 surround systems in automobiles has raised the question of how to evaluate their performance. Multichannel systems have significantly different spatial characteristics compared to 2-channel stereo systems. It is therefore appropriate to review the validity and reliability of the current methods and to assess whether they can cover this significant change in the spatial attributes. A workshop at the 117th Convention discussed some of the current methods and related issues. At this same Convention, a number of automotive listening tests and surveys were staged to illustrate some of these complexities. This workshop will provide feedback of selected results. A team of recognized experts in the field of scientific methodologies will discuss the pros and cons of the methods, the data analysis, and the conclusions that can be inferred from these experiments. Although this workshop relates to an automotive environment, the debate will delve into the important generic issues of validity and reliability in subjective testing and will therefore be useful to anyone who wants to find out more about this field.
