‘喧噪’ is a compound noun meaning ‘uproarious noise’ or ‘clamor’—a loud, chaotic, and often irritating mixture of sounds. The first character 喧 (xuān) means ‘noisy’ or ‘boisterous’, especially from many voices or activity; the second 噪 (zào) means ‘to make noise’ or ‘din’, often implying harsh or grating sound. Together, they emphasize persistent, overwhelming auditory disturbance—not just volume, but also lack of harmony or control.

This word is commonly used to describe environments where multiple sources of sound collide: crowded markets, construction sites, or flocks of birds at dawn. It carries a slightly negative connotation, suggesting discomfort or disruption. While it can apply to human crowds, it’s especially frequent in ecological or nature writing—for instance, describing the piercing, overlapping calls of cicadas or crows—making it relevant to the ‘Animals’ topic due to its vivid use in depicting animal-generated commotion.
