Accelerated construction of stress relief music datasets using CNN and the Mel-scaled spectrogram.

Listening to music is a crucial tool for relieving stress and promoting relaxation. However, the limited options available for stress-relief music do not cater to individual preferences, compromising its effectiveness. Traditional methods of curating stress-relief music rely heavily on measuring biological responses, which is time-consuming, expensive, and requires specialized measurement devices. In this paper, a deep learning approach to solve this problem is introduced that explicitly uses convolutional neural networks and provides a more efficient and economical method for generating large datasets of stress-relief music. These datasets are composed of Mel-scaled spectrograms that include essential sound elements (such as frequency, amplitude, and waveform) that can be directly extracted from the music. The trained model demonstrated a test accuracy of 98.7%, and a clinical study indicated that the model-selected music was as effective as researcher-verified music in terms of stress-relieving capacity. This paper underlines the transformative potential of deep learning in addressing the challenge of limited music options for stress relief. More importantly, the proposed method has profound implications for music therapy because it enables a more personalized approach to stress-relief music selection, offering the potential for enhanced emotional well-being.

Effects of anxiety-related psychological states on music-induced analgesia in cold pressor pain responses.

CONTEXT: The analgesic effect of music has long been reported. OBJECTIVE: To assess how anxiety-related psychological states affect the analgesic effect of music using the cold pressor task (CPT). DESIGN: A 3-period × 3-sequence crossover design was adopted; three conditions were used: "no sound," "music-listening," and "news-listening." SETTING: PARTICIPANTS: Forty-nine participants were included. INTERVENTIONS: After completing five anxiety-related psychological instruments (Anxiety Sensitivity Index [ASI]-16, ASI-Revised, State-Trait Anxiety Inventory [STAI]-S, STAI-T, and Pain Anxiety Symptoms Scale-20), the participants were allocated to the low- or high-anxiety group. The high- and low-anxiety groups were defined based on cutoff points according to the distributions and characteristics of the five instruments. MAIN OUTCOME MEASURES: Pain responses, such as pain tolerance time, pain intensity, and pain unpleasantness, were measured on the CPT. Pain responses in the music-listening condition were also compared to those in the other two conditions via pairwise comparisons within each anxiety group. RESULTS: The Cronbach alpha of the five instruments ranged from 0.866 to 0.95, indicating that they were reliable. Pain responses in the music-listening condition in the low-anxiety groups based on any of the five scales were significantly different from those in the other conditions, but this effect was not found in the high-anxiety groups. This study demonstrates that anxiety-related psychological states can predict the analgesic effect of music on pain responses measured by the CPT and suggests that music may be beneficial as a pain management tool in low-anxiety groups.

The analgesic effect of music on cold pressor pain responses: The influence of anxiety and attitude toward pain.

OBJECTIVE: The analgesic effect of music has been recognized for pain relief, but individual differences and adjuvant methods are poorly understood. This study employed a cold-pressor task (CPT) to observe the effects of music (without considering personal preferences) on pain experience and how this is affected by individuals' general (and pain-specific) anxiety symptomology. METHODS: Fifty participants were each presented with three conditions (randomized into different orders): music-listening, news-listening, and no sound (control). Pain responses, including pain tolerance time (PT), pain intensity (PI), and pain unpleasantness (PU), were assessed using CPT and compared with a 3x3 crossover design. Participants also completed the anxiety sensitivity index (ASI-16) and pain anxiety symptom scale (PASS-20). RESULTS: CPT pain responses during the music intervention were significantly different from responses during the news intervention and control conditions, respectively. Among participants with normal anxiety levels, pain responses during the music condition differed significantly from the news and control groups; this was not the case for the anxiety risk group. Pain responses during the music condition for those with normal levels of pain-specific anxiety differed significantly from the control, but this was not the case for the risk group. CONCLUSIONS: Music appears to influence diminished pain responses relative to the absence of an intervention. However, this was not the case when individuals listened to news stories. These effects were more robust for individuals experiencing normal levels of general and pain-specific anxiety. Thus, music (even outside one's own preferences) was an effective adjuvant method for managing pain, especially among those without significant anxiety symptomology.

Crossover clinical trial of pain relief in cataract surgery.

PURPOSE: To determine the effects of intra-operative Korean traditional music on pain experienced by Korean patients undergoing sequential bilateral cataract surgery. METHODS: This was a two-sequence, two-period, and two-treatment crossover study. Fifty-two patients with cataracts were divided into two groups by block randomization, and bilateral cataract surgery was performed. In group 1, patients listened to Korean traditional music (KTM) during their first but not second cataract surgery. This sequence was reversed for patients in group 2. After each surgery, patients scored their pain intensity (PI) using a visual analog scale (VAS) ranging from 0 to 10, where 0 was 'no pain' and 10 was 'unbearable pain.' RESULT: There was a statistically significant reduction in the mean VAS score with KTM (3.1 ± 2.0) compared to that without KTM (4.1 ± 2.2; p = 0.013). However, there were no statistically significant differences in blood pressure or pulse rates. CONCLUSION: KTM had a significant effect on reducing pain experienced by patients during cataract surgery. This may be useful in the context of other surgical procedures to reduce pain in Korean patients.
