One of the reasons this may have happened is because the audience does not ‘read’ sound in the same way that it does the visual image. Sound is not only omnipresent but also omni-directional and this pervasiveness led to it being traditionally discounted as an important medium of film. These days, the same pervasiveness is considered beneficial and filmmakers have learnt that sound can be manipulated effectively to enhance a film. The fact is, sound is sometimes far more effective a medium in film than the visual image.
