Perceptual Evaluation of Mobile Multimedia Loudspeakers
AES Convention 122 · Paper 7050 · May 2007
Abstract
An experiment was conducted to compare the perceptual characteristics of stereo loudspeaker systems found in mobile multimedia devices. A descriptive sensory analysis was performed using an individual vocabulary development approach. Ten systems and five musical programs were selected for this study. Sixteen listeners developed their own set of attributes in three hours and performed a comparative evaluation of the ten systems for several program items using the attribute scales they developed. A total of 111 attributes was generated in this experiment, which could be divided into several perceptual groups relating to loudness, spatial and timbral aspects, sound disturbance and sound articulation. The principle of this individual vocabulary profiling method is described and some results of the perceptual evaluation are presented.
