In our world, many things cannot lack sound. Sound is like water and air to me, which is very significant.
Sound arts can be applied in many fields, such as movies, VR, games and installations, etc. So I think sound occupies a part of the power in human occupations and activities.

The Shining which directed by Stanley Kubrick is a horror movie I like. The soundtrack of this film is very scary. If I just watch the screen and don’t listen to the sound, I don’t think it’s very terrible. With the development of current technology, many films now have good soundtrack and sound effects. Today’s films have developed very well both visually and acoustically.
In addition, I think sound art is very complex and difficult to explain, but it can be a state or a medium to build a bridge between the audience and the author. I think sound art can be divided into traditional and non-traditional. The traditional is a very direct form of expression such as some music. The other non-traditional is like some artists’ installation, which are combined in sound and digital media to show the audience the uniqueness and non replicability of sound art.

All in all, I think the sound is also related to people themselves. Maybe young and old people will hear different sound, and men and women are different. The sound can also recall memories. Just like being in a foreign land, when we hear the songs of our homeland, we may have the idea of missing. So sound art is hard to explain.
