Single Vibroacoustic Impact Effect of Singing Bowls over the Psycho-Emotional State and Cardiovascular System Work

This article presents a two-stage study result of the author's method of vibroacoustic massage using singing bowls application. At the first stage, the effect of vibroacoustic massage single application over psycho-emotional characteristics was studied. 19 studied volunteers took part in our study. The testing results before and after exposures were compared according to the WAM (Weighted average mark), Zung, and Spielberg-Khanin tests. The study of the psycho-emotional sphere showed that after the vibroacoustic massage procedure, the indicators of "well-being" and "activity" of the WAM test significantly improved (p = 0.002). In addition, the depression level determined by the Zung test, personal anxiety indicators (p = 0.004), and situational anxiety ones (p = 0.028) decreased. At the second stage, 62 volunteers were divided into two groups. The first group underwent a vibroacoustic massage session according to the patented author's method. The second group received only acoustic exposure using only singing bowls. Differences in the Kerdo index were revealed in the dynamics, and in the first group, the changes were less significant than in the second one. Changes in heart rate variability characteristics for both groups were similar: there was an increase in parasympathetic influences at rest and during the orthostatic test (increased levels of RMSSD (Root Mean Square of Successive Differences), NN50, pNN50) and a decrease in sympathetic effects at rest and their slight increase with orthostatic loading (TINN, RR triangular index). The dynamics were more significant in the first group that received a vibroacoustic massage session. When assessing changes in the neurovegetative regulation levels activity of the heart rhythm, the main difference was associated with very low-frequency waves power dynamics during the orthostatic test. Thus, vibroacoustic massage using singing bowls improves the psycho-emotional state, reduces depression and anxiety, and increases Parasympaticus (autonomic nervous system) activity.

Impact of Himalayan Singing Bowls Meditation Session on Mood and Heart Rate Variability – An Observational Study

Introduction Scientific evidence has demonstrated the psychological and physiological benefits of meditation. Sound vibrations also improve emotional wellbeing while enhancing the physiological parameters. There is an opportunity to explore the psychological and physiological benefits of Himalayan Singing Bowls (HSB) sound bath meditation, i.e. meditation assisted with sound vibrations. Aim of the Study The study explored changes in mood and Heart Rate Variability (HRV) parameters after a HSB Sound Bath Meditation on healthy individuals. The primary objectives of the study were to understand if a 40 minute long seated HSB Sound Bath Meditation results in significant improvement (a) in positive affect and negative affect, as measured by Positive And Negative Affect Scale (PANAS) and (b) in physiological parameters, as measured by Heart Rate Variability. The secondary objective of the study was to understand the impact on various moods as measured by Profile Of Mood States (POMS) Survey. Methods The psychological parameters included changes in Positive and Negative Affect (measured on 77 individuals using PANAS) and changes in specific, positive and negative moods (measured on 17 individuals using POMS) before and after the meditation session. The physiological parameters included HRV parameters such as Heart Rate (HR), Stress Index (SI) and Root Mean Square of Standard Deviation (RMSSD) measuring during the entire session on 15 individuals using the EmWave Pro device. HRV data analysis was conducted with Kubios HRV Premium and all the data was analyzed using paired T-Test. Results All the subjects after meditation showed statistically significant improvement in Positive Affect (mood) and a reduction in Negative Affect (mood). The HRV parameters showed a trend demonstrating overall relaxation with a statistically significant reduction in HR, Stress Index and an increase in RMSSD in the last 5 minutes as compared to the first 5 minutes. Consistent with changes in positive, negative mood and HRV, all the participants showed statistically significant reduction in tension, anger, fatigue, depression and confusion. In terms of positive mood, there was a statistically significant improvement in esteem related affect and an increase (but not statistically significant) in vigor. Conclusion The findings demonstrate that seated HSB Sound Bath Meditation session has a positive impact on the mood related measures. The physiological changes measured during the meditation using HRV parameters indicated a consistent reduction in Heart Rate throughout the meditation and a reduction in overall sympathetic tone and an increase in parasympathetic tone. Thus, HSB can be used to improve both psychological and physiological parameters even after one 40 min session. Future work in this area could explore comparison with a control group and a longer study duration consisting of multiple sessions.

A Comparative Study of the Impact of Himalayan Singing Bowls and Supine Silence on Stress Index and Heart Rate Variability

Introduction Sound vibrations have a profound impact on the body and the mind with evidence confirming reduced anxiety and increased wellbeing. The likely reason for driving the benefit is relaxation. The Himalayan Singing Bowls, used for therapeutic intervention to enhance the individual’s emotional & physical wellbeing, may facilitate faster and deeper relaxation as compared to simple, supine relaxation. Aim of the Study The study aimed to validate the hypothesis that short 20 minutes sessions to relax with the help of the Himalayan Singing Bowl (HSB) could provide better depth of relaxation as compared to Supine Silence (SS) based on the objective assessment of physiology parameters i.e. Stress Index & Heart Rate Variability (HRV). Methods Seven metal Himalayan singing bowls were used in a particular sequence learned from an expert teacher for 16 subjects. The SS group consisted of 17 subjects. The HRV data was measured by the Emwave Pro device and analyzed using Kubios HRV Premium software. The analysis compared key HRV parameters within and between the groups. Result Overall, as expected, both groups achieved relaxation as measured by changes in HRV parameters. However, further analysis confirmed a more consistent relaxation, as measured by a statistically significant reduction in stress index and an increase in HRV, for HSB group. The HSB group achieved more consistent depth of relaxation during each subsequent 5 minutes interval throughout the session as compared to SS group. Conclusion The study confirms that singing bowls sessions can be leveraged as a tool for inducing good quality relaxation response (increased parasympathetic tone, reduced stress) to facilitate healing and energy recovery in just 20 minutes and achieve significant health benefits. More comprehensive studies must be conducted to further evaluate the findings with more sample size, different methods of relaxation and varied demographics.

Vibration modes and sound characteristic analysis for different sizes of singing bowls

The singing bowl is used not only for the instrument of Buddhism but also for musical therapy. This work aims to investigate the correlation of vibration modes and percussion sound for singing bowls. A typical singing bowl is first selected to perform finite element analysis (FEA) for theoretical modal analysis (TMA) as well as experimental modal analysis (EMA). Modal parameters of singing bowl, including natural frequencies and mode shapes, can be obtained from analysis and experiment, respectively. Singing bowl FE model can then be updated and verified by adjusting material properties and used to predict structural vibration modes. The percussion sound of singing bowl is also measured to obtain its sound spectrum. The peak frequency response of singing bowl sound can be interpreted and contributed from circular vibration modes of the bowl. With the knowledge of sound generation mechanism for the singing bowl, this work also studies the percussion sound characteristics of seven different sizes of singing bowls. Results show the fundamental frequency and overtone frequencies of singing bowl percussion sound are higher for the smaller size. Interestingly, that the peak resonant frequencies have near the integer ratio relationship makes the singing bowl revealing harmony sound effects. The radiated sound spectrum can be well calibrated and predicted for different sizes of singing bowls. This work shows the analytical and experimental approaches in studying the singing bowl percussion sound that strongly correlated to structural vibration modes and can be adopted for future development of singing bowls.
