In general, the Anonymous Noise anime is comparable to the manga. Some minor details might be different, but the core elements and themes remain intact. There are also visual and audio enhancements in the anime that add to the experience.
You can start by describing the type and volume of the noise. For example, a loud thunderclap or a soft rustling of leaves. Make it relevant to the scene or the character's emotions.
White Noise is typically classified as a postmodern novel. It incorporates diverse narrative techniques, explores themes of consumerism and media saturation, and defies straightforward categorization found in modernistic works.
