This book clearly and pleasantly combines the necessary explanation of the technical-physical concepts of the production, transmission and reception of sound, and also presents in an orderly manner the most recognized theories about the impact of sound as an active element within audiovisual expression.
Special interest and abundant references are devoted to the relationships between the functioning of the brain and music, as well as to the different forms of sound perception, when the fundamental elements of the theories of the French Pierre Schaeffer and the German Ernest Schachtel are exposed.
