Interactive sound installations are artistic environments where sound is generated or altered by the presence and actions of visitors. These installations often use sensors, microphones, or other technology to respond to movement, touch, or even voice, creating a unique auditory experience for each participant. Artists like Janet Cardiff and George Bures Miller have pioneered this form of art, inviting audiences to engage with sound in new ways. The installations can be found in galleries, public spaces, or festivals, encouraging exploration and interaction, making sound a dynamic part of the viewer's experience.
