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. Artists create immersive environments that engage the audience's auditory senses, encouraging them to explore the relationship between sound and space. Typically, sound installations may incorporate various technologies, such as speakers, microphones, and sensors, to enhance the experience. Notable artists in this field include John Cage and Janet Cardiff, who have pushed the boundaries of how sound can be perceived and experienced in different contexts.
