Arnheim treats all aspects of sound. He explores words and music as kinds of sounds; discusses direction and distance, spatial resonance, sequence and juxtaposition in radio sound; makes comparisons between sound film and radio techniques and effects; and details the benefits of imagination with sound from a creative and emotional point of view. The art of announcing, the psychology of the listener, and two generalized discussions of radio around the world, and the prospects for television are covered in the last chapters.
