Differences in Performance and Preference of Trained versus Untrained Listeners In Loudspeaker Tests: A Case Study

摘要

Listening tests on four different loudspeakers were conducted over the course of 12 months using 25 different groups of listeners. The groups included 184 untrained listeners whose occupations fell under one of four categories: audio retailer, marketing and sales, professional audio reviewer and college student. The loudspeaker preferences and performance of these listeners were compared to those of a panel of 12 trained listeners. Significant differences in performance, expressed in terms of magnitude of loudspeaker F-statistic (FL) were found between the different categories of listeners. The trained listeners were the most discriminating and reliable listeners with mean FL values 3-27 times higher than the other four listener categories. Performance differences aside, loudspeaker preferences were generally consistent between all categories of listeners, providing evidence that the preferences of trained listeners can be safely extrapolated to a larger population of untrained listeners. The highest rated speakers had the flattest measured frequency response maintained uniformly off-axis. Effects and interactions between training, programs and loudspeakers are discussed.
