✦ Synopsis
This study investigated the e!ect of steady noise, #uctuating noise and music on circulatory function. Pulse-wave and blood pressure were continuously measured in 35 healthy young females who listened to three types of music or were exposed to steady noise or #uctuating noise, synchronized with each type of music with respect to intensity variations. The pulse-wave did not change during any exposure conditions. Regarding blood pressure, several modes were observed. The critical level for a blood pressure change was estimated to be 54¸ CO during exposure to steady noise. The frequency of high-intensity peaks in the mode of sound #uctuation was associated with elevation in blood pressure. The blood pressure change was analyzed by distinguishing the intensity variation in sound #uctuation from other attributes of music. The e!ects of music on blood pressure were modi"ed not only by the melody and timbre of the music but also by emotional responses during listing.
