As the audio begins, a distinct rustling sound fills the air. It's an unmistakable noise that you would associate with the interaction with a polythene sack. The plastic material, thin and lightweight, is being manipulated, causing a harsh, almost grating sound. The polythene sack is being used, perhaps filled, or maybe emptied. It's a continuous, somewhat loud noise, evoking the sensation of a tactile interaction with the plastic material. The noise gradually subsides, leaving a lingering hint of the harsh, plastic sound that has been the centerpiece of the audio. The audio ends, leaving behind the distinct memory of the polythene sack's interaction.
