Elements of 4D_ aynsley haugk

 In this article, the author introduced the element of sound as a vibration that can be heard through your ears. Sound is a tool used in communication, music, language, nature, etc. Sound can also be used to alert you of your surroundings, for example, a waterfall makes a loud noise as you get closer and closer hinting that you should be aware of the large body of water. 

In the article, the author emphasises the 5 categories of sounds, synchronous, nonsynchronous, asynchronous, diegetic, and non-diegetic. Synchronous is when you are in a time-based performance space like a play or a TV show. Nonsynchronous is when you hear a sound onscreen but you can not see where it is coming from, or at least not yet. Asynchronous sound is when the sound we hear doesn't match what we see, for example, kid snippets use kids' voices and sincs it over the adults so it looks like they speak like a child. Diegetic sound is sound created by the environment of the work. For example, a sound when a girl is walking in a field on a TV show. Non-diegetic sound is created outside of the environment of the work and is usually commentary or giving information, for example, narration.
