The Difference in Perceptual Attributes for the Distortion Timbre of the Electric Guitar between Guitar Players and Non-Guitar Players

摘要

Subjective evaluation experiments were performed to reveal the perceptual attributes for the distorted timbre of the electric guitar. The motivation was to gain smoothness in conversation over the distorted timbre between guitar players and non-guitar players at the recording sessions. The signals of three guitar performance were distorted in three different amount of distortions with three kinds of frequency characteristics. That bring the total to twenty-seven stimuli. Sixteen non-guitar players and sixteen electric guitar players participated in the rating experiments using semantic scales anchored by eight bipolar adjective pairs. The result indicated both had similar perceptual attributes for distorted guitar timbres. One latent factor was found and was correlated with the acoustic features. The alterations of frequency characteristics did not appear as the variable affecting the judgment of distortion timbres.
