Pleasant Music And Silence During Task Performance

The effect of participants selective like/ pleasant and dislike/unpleasant music on cardiovascular measures like heart rate, blood pressure, respiratory rate and oxygen saturation.
The mean heart rate was significantly different (Z=-2.815, p=0.004) between pleasant music and silence at without task performance (Task 1). Figure 4.20 shows that the mean heart rate was less (74 beats/min) while listening to pleasant music when compared to silence (78.4 beats/min). The mean heart rate was significantly different (Z=-2.823, p=0.005) between unpleasant music and silence at Task 1. The mean heart rate was significantly high for unpleasant music listeners as compared to participants in silence mode. Under task performance (Task 2), the mean heart rate
The mean heart rate was significantly less for pleasant music listeners as compared to unpleasant music listeners under Task 2 condition. Figure 4.21 show that the pleasant and unpleasant music had significant effect on heart rate between Task 1 and Task 2 performances. The heart rate were significantly (p<0.05) higher while listening to unpleasant music as compared to pleasant music in both the task performances.
It was found that there was no significant difference in the oxygen saturation level between the silence mode, listening to pleasant and unpleasant music.
These changes induced in the brain were reflected in the measured cardiovascular parameters the mean heart rate, systolic pressure, diastolic pressure and mean arterial pressure (MAP) reduced while listening to subjects preferred pleasant music (Low arousal /Positive valence ) when compared with baseline and rest 1 ( after listening to Music). These changes were reversed while listening to unpleasant music. The mean heart rate reduced to 74 beats / min while listening to like music when compared with baseline and rest 1 (79 beats / min). The mean arterial pressure (MAP) reduced to 91 mm of Hg while listening to like
The cardiovascular parameters reduced while listening to like music. These changes were reversed while listening to dislike music. While listening to subject selective dislike music the heart rate, systolic, diastolic and mean arterial pressures, respiratory rate, increased when compared with baseline and rest 1. The mean heart rate increased to 84 beats / min while listening to dislike music when compared with baseline and rest 1 (79 beats / min). The mean arterial pressure (MAP) increased to 99 mm of Hg while listening to dislike music when compared to baseline and rest 1 (95 mm of Hg).The respiratory rate increased to 23 / min while listening to dislike music when compared to baseline and rest 1 (19 / min). The changes in heart rate, systolic, diastolic and mean arterial pressures were noted while listening to like music and it reduced when compared to rest 1, baseline and dislike music. In addition to that, these parameters increased while listening to dislike music when compared to rest 1, baseline and like music. Heart rate, systolic, diastolic, mean arterial pressures and respiratory rate were same throughout the rest 1 and
