Professor Bartel of the Faculty of Music and his team in the Music and Health Research Collaboratory are exploring the medical effects of low frequency sound and have demonstrated it can play a key role in reducing the symptoms of Parkinsons Disease.
“Vibroacoustic therapy (VAT) consists of low sound frequencies that are transmitted to the body and mind through special transducers that convert the sound to inner body massage. MaHRC associates Heidi Ahonen and Quincy Almeida treated two groups of Parkinson’s patients (20 with dominant tremor symptoms and 20 with slow/rigid movement symptoms) with five minutes of 30 Hz vibration.”
