Psychoacoustics is the study of the perception of sound. This includes how we listen, our psychological responses, and the physiological impact of music and sound upon the human nervous system. In the realm of psychoacoustics, the terms music, sound, frequency, and vibration are essentially interchangeable, because they are different approximations of the same essence.
Joshua Leeds, a sound researcher, producer, and composer, is one of few published authorities on the psychoacoustic effects of music and sound. Psychoacoustics is also the over-arching theme of his book, The Power of Sound (Healing Arts Press, 2001, 2010).
Within this website, you will find detailed information about The Power of Sound and Joshua Leeds. Additionally, Frontiers of Soundwork contains a brief history of soundwork and significant research links. The Sonic Activist serves as a networking source for those interested in preserving balanced soundscapes in home and community.
