No Noise Symbol - Silence and Quiet Zone Signage #3665455 (License: Personal Use)

The image displays a bold prohibition sign-a red circle with a diagonal slash-overlaid on a black megaphone emitting sound waves. The design follows international safety signage conventions, using high-contrast colors (red, black, white) for immediate recognition. It conveys the instruction to refrain from making loud noises or using amplification devices.

Commonly used in libraries, hospitals, schools, meditation spaces, theaters during performances, and residential quiet hours; matches user intent seeking visual cues for noise restriction policies or signage design.
