A standard Polaroid film was proved to be applicable to a quick and easy direct mapping of an acoustic field. The method utilizes the effect of an acoustic field on the developing process of a uniformly pre‐exposed Polaroid film. The method would be most useful for visualization of acoustic field as well as preparing acoustic holograms.
