摘要：The relationship between a subjective evaluation and the corresponding P300 of an event-related potential(ERP) was investigated.The ERP was measured when still TV pictures degraded by a burst noise were subjectively evaluated on a four-grade impairment scale:“Not Annoying”,“Slightly Annoying”,“Annoying”,and “Very Annoying”.Although there was no significant correlation between the opinion scoring and the P300 amplitude,the results showed that large and distinguishable P300 amplitudes appeared when the subjects evaluated a noise as “Very Annoying”.
