Integrative Use of Sound Therapy for Mental Health Promotion

Summary

This randomized clinical trial aims to evaluate the effectiveness of sound therapy in improving mental health and quality of life. Participants will be randomized into two groups: an intervention group using an acoustic resonance chamber and a control group using headphones. Both groups will be exposed to specific sound frequencies for nine minutes, once a week, for three weeks. The study investigates associations between sound therapy and levels of anxiety, stress, depression, and quality of life.

Interventions

PROCEDURE

Acoustic Resonance Sound Therapy

Participants will receive sound therapy in 3 sessions, one session per week, each lasting 9 minutes. The protocol uses 9 sound frequencies as follows: session 1 will use the frequencies of 396 Hz (close to the note G), 639 Hz (close to the note E), and 963 Hz (close to the note B); session 2 will use the frequencies of 174 Hz (close to the note F), 417 Hz (close to the note G sharp), and 741 Hz (close to the note F sharp); and session 3 will use the frequencies of 285 Hz (close to the note D), 528 Hz (close to the note C), and 852 Hz (close to the note A), with each frequency applied for three minutes. Sound therapy is performed inside an acoustic resonance chamber, designed to optimize sound pressure distribution.

PROCEDURE

Control Group with Headphones

Participants will receive sound therapy in 3 sessions, one session per week, each lasting 9 minutes. The protocol uses 9 sound frequencies as follows: session 1 will use the frequencies of 396 Hz (close to the note G), 639 Hz (close to the note E), and 963 Hz (close to the note B); session 2 will use the frequencies of 174 Hz (close to the note F), 417 Hz (close to the note G sharp), and 741 Hz (close to the note F sharp); and session 3 will use the frequencies of 285 Hz (close to the note D), 528 Hz (close to the note C), and 852 Hz (close to the note A), with each frequency applied for three minutes. Participants receive the sound protocol through headphones, while remaining seated.
