This disorder can have a significant impact on health, affecting the individual's overall well-being and quality of life. The sudden exposure to high-intensity sounds can lead to various physical and psychological effects, disrupting the body's natural balance and causing distress. Managing and understanding this disorder is crucial to prevent further health complications and improve the individual's overall health and well-being.
