Abstract
Generally, sound or music has been used to heal one’s mind for centuries. However, it can also cure mental and physical problems we may have, directly. In this paper, we will discuss what sound can practically do to the society, especially in the welfare and medical front. By showing the examples of the works we have done, we will explain the important aspects of sound; that it can evoke one’s imagination, and that it is the best tool to make the atmosphere of any space. We found that sound can help people in the hospital, for example, with giving relaxation during the treatment, with improving QOL of the workers related, or with facilitating the communication with patients, by maximizing the special features that only sound has.
