How noisy is an airbrush setup?

Modern dedicated airbrush compressors are remarkably quiet:

• Standard desktop units (like the GTS-06 or GT-918) operate between 47-52 DB, which is equivalent to a quiet indoor conversation, a dishwasher, or a household refrigerator.
• They produce zero structure-shaking vibration and can easily be used in apartments, shared living rooms, or during late-night hobby sessions without disturbing others.
