Quietness is important in libraries, where people read and study. Being quiet there isn't just a rule, it's to create a good study environment. Also, in quiet areas at schools or universities, the silence helps people concentrate, which is good for learning.

Silence is also needed in hospitals, near patients' rooms. It respects the healing process and gives patients peace. Also, when we visit sick or resting people, speaking softly shows we care and lets them have the quiet they need to get better.
