Sensory profiling of high-end loudspeakers using rapid methods - Part 3: Check-all-that-apply with naïve assessors

This paper is the third in a series of papers investigating the use of rapid methods for sensory profiling of high-end loudspeakers [1, 2]. In this study check-all-that-apply (CATA) was introduced as a method for perceptual audio evaluation. A preliminary test was conducted with naive assessors to reduce a list of attributes to a suitable number for a CATA question. A listening test was then conducted with naive assessors using the CATA method, and two methods for characterizing the loudspeakers were explored using Correspondence Analysis (CA) and Hierarchical Cluster Analysis (HCA). The CATA method was able to produce discriminative and descriptive characterizations of the loudspeakers. Further steps to refine the method for the purpose of perceptual audio evaluation with naive assessors are discussed.
