Dolphin sounds might be doing more than just echoing underwater 🐬✨ Their ultrasonic clicks, which range from 2,000 Hz to 100,000 Hz, are believed to have therapeutic effects for children with cerebral palsy. These high-frequency vibrations can gently influence brain activity — helping with relaxation, neural balance, and muscle control. In dolphin-assisted therapy, the combination of sound, touch, and emotional connection is thought to reduce anxiety and boost engagement during rehabilitation.
