We use internal(chanting etc.) and external (sound bowls) sounds to generate the vibration and use it as healing modality. We not only hear sounds by ears but every cell of the body feels and responds it. Sound therapy is very effective as it influences our emotional bodies as well as physical bodies . Stress reduction is one of the important results of sound therapy. As stress is underlying cause of many physical conditions and it melt away with ease when you are bathed in a sea of sound healing vibrations.
