基于音色属性辨识声目标的主观评价实验研究
摘要
Three subjective evaluation experiments involving in target recognition, semantic differential (SD) and adaptive grouped paired comparison (AGPC) were designed and performed to investigate the effect of timbre attributes on acoustic target discrimination. Firstly, 50 sound samples of equalized loudness and duration were used to subjectively identify three kinds of targets. Then SD and AGPC based target discrimination experiments were carried out, and the experimental data were processed using coherence and clustering approach to explore the roles of the two kinds of timbres, natural timbre and essential timbre, in the identification of acoustic targets. This work provides some insight into timbre mechanisms inherent in auditory object identification and timbre modeling applied to auditory feature extraction and target recognition.
