“…Moreover, this result is in agreement with the current literature showing the crucial role of LPP analysis during acoustic elicitation [70]- [74]. Among the other LPP measures, the SD1 measures, which represents the instantaneous beat-to-beat variability of RR intervals, and SD12, which represents the ratio between the two standard deviations, have been associated to the parasympathetic activity [43], [75], [76]. Thus, a decrease of these indices could be associated to a corresponding reduction of the parasympathetic modulation.…”

“…A relevant contribution was given by nonlinear parameters of defined by LPP. This finding confirms the relevant contribution of nonlinear analysis in the affective computing field, especially in the analysis of cardiac signals [5], [43], [70].

“…In this study, features extracted from Poincaré plots were also taken into account. Specifically, we engaged geometric indices of Lagged Poincaré plots (LPP) which have already been successfully proposed in the literature in studies involving acoustic stimulation [41]- [43]. Therefore, we included these features in our set of HRV nonlinear measures.…”

This paper reports on how emotional states elicited by affective sounds can be effectively recognized by means of estimates of Autonomic Nervous System (ANS) dynamics. Specifically, emotional states are modeled as a combination of arousal and valence dimensions according to the well-known circumplex model of affect, whereas the ANS dynamics is estimated through standard and nonlinear analysis of Heart rate variability (HRV) exclusively, which is derived from the electrocardiogram (ECG). In addition, Lagged Poincaré Plots of the HRV series were also taken into account. The affective sounds were gathered from the International Affective Digitized Sound System and grouped into four different levels of arousal (intensity) and two levels of valence (unpleasant and pleasant). A group of 27 healthy volunteers were administered with these standardized stimuli while ECG signals were continuously recorded. Then, those HRV features showing significant changes (p<0.05 from statistical tests) between the arousal and valence dimensions were used as input of an automatic classification system for the recognition of the four classes of arousal and two classes of valence. Experimental results demonstrated that a quadratic discriminant classifier, tested through Leave-One-Subject-Out procedure, was able to achieve a recognition accuracy of 84.72% on the valence dimension, and 84.26% on the arousal dimension.

“…We wonder whether acoustic stimulation reduces the global HRV. Conversely, Roy and co-workers (19) investigated the effects of a novel auditory binaural stimulus, called rotating acoustic stimulus, on the cardiac autonomic responses. The authors observed a decrease in the HR and an increase in the time domain RMSSD, SD1, SD2 and the SD1/SD2 ratio after the stimulation.…”

OBJECTIVES:There are no data in the literature with regard to the acute effects of different styles of music on the geometric indices of heart rate variability. In this study, we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of heart rate variability in women.METHODS:We conducted this study in 21 healthy women ranging in age from 18 to 35 years. We excluded persons with previous experience with musical instruments and persons who had an affinity for the song styles. We evaluated two groups: Group 1 (n = 21), who were exposed to relaxant classical baroque musical and excitatory heavy metal auditory stimulation; and Group 2 (n = 19), who were exposed to both styles of music and white noise auditory stimulation. Using earphones, the volunteers were exposed to baroque or heavy metal music for five minutes. After the first music exposure to baroque or heavy metal music, they remained at rest for five minutes; subsequently, they were re-exposed to the opposite music (70-80 dB). A different group of women were exposed to the same music styles plus white noise auditory stimulation (90 dB). The sequence of the songs was randomized for each individual. We analyzed the following indices: triangular index, triangular interpolation of RR intervals and Poincaré plot (standard deviation of instantaneous beat-by-beat variability, standard deviation of the long-term RR interval, standard deviation of instantaneous beat-by-beat variability and standard deviation of the long-term RR interval ratio), low frequency, high frequency, low frequency/high frequency ratio, standard deviation of all the normal RR intervals, root-mean square of differences between the adjacent normal RR intervals and the percentage of adjacent RR intervals with a difference of duration greater than 50 ms. Heart rate variability was recorded at rest for 10 minutes.RESULTS:The triangular index and the standard deviation of the long-term RR interval indices were reduced during exposure to both music styles in the first group and tended to decrease in the second group whereas the white noise exposure decreased the high frequency index. We observed no changes regarding the triangular interpolation of RR intervals, standard deviation of instantaneous beat-by-beat variability and standard deviation of instantaneous beat-by-beat variability/standard deviation in the long-term RR interval ratio.CONCLUSION:We suggest that relaxant baroque and excitatory heavy metal music slightly decrease global heart rate variability because of the equivalent sound level.
