Sound installations are artistic works that use sound as a primary medium. These installations can be found in galleries, museums, or public spaces, and often involve a combination of recorded audio, live performances, and interactive elements. The goal is to create an immersive experience that engages the audience's senses and emotions. Artists like John Cage and Janet Cardiff have pioneered this form of art, exploring how sound interacts with the environment and the viewer. Sound installations can vary widely in style and purpose, from calming soundscapes to thought-provoking auditory experiences, inviting participants to reflect on their surroundings.
