“On the Knocking on the Gate in Macbeth” is a classic that still deserves to be explored in depth 200 years later. It provides a crucial moment of understanding of the effects of sound, and through a Romantic critique of a simple yet effective theatrical sound event, De Quincey implies that ‘time must be annihilated; connection with external objects must be abolished’. It provokes reflection on the importance of sound in theatre. Using the example of the tapping on the door in Macbeth, De Quincey explores how sound is a crucial element in theatre and how it can affect the emotions and experiences of the audience by creating compelling scenes and situations. This led to a reflection on the role of sound in theatre and how sound effects can profoundly affect the feelings and emotions of the audience. The article also provoked reflection on the perception and distortion of time, with De Quincey noting that through sound we can distort, stretch, or abolish the perception of time. The banging on the door creates an atmosphere of tension and suspense in the play, whilst at the same time making the audience feel as if time has been compressed or stretched. This reminds us of the unique ability of sound to create situations and moods, and how it affects our perception and understanding of time. Through sound, we can evoke inner feelings and emotions, creating a profound psychological experience. Radio, as a medium of communication, has the unique ability to create engaging sound worlds that immerse and resonate with the listener through carefully designed sound effects and audio technology.
