Sensory Profiling of High-End Loudspeakers Using Rapid Methods—Part 2: Projective Mapping with Expert and Naïve Assessors

This is the second of a series of papers evaluating the efficiency of rapid sensory profiling methodologies in the audio field [1]. The present paper introduces projective mapping [2] as a method for perceptual audio evaluation and demonstrates its application for discrimination and description of a set of high-end loudspeakers. Additionally, the suitability of the method with both experts and naïve assessors was evaluated. The results showed a successful discrimination between the loudspeakers with the main differences primarily associated to bass strength and bass depth. A high degree of agreement was observed between perceptual configurations obtained separately by the expert and the naïve assessors, though the former outperformed the latter in the descriptive part of the method.
