A "Quiet Zone" is a designated area where noise is minimized to create a peaceful environment. These zones are often found in libraries, hospitals, and certain public spaces, allowing individuals to focus, relax, or engage in quiet activities without disturbances. In the United States, one notable example is the National Radio Quiet Zone, which spans parts of West Virginia and Virginia. This area restricts radio transmissions to protect the sensitive equipment at the Green Bank Observatory, enabling scientists to conduct research on celestial phenomena without interference from man-made signals.
