This infographic presents a progressive noise level scale ranging from 0 (extra quiet/listening) to 5 (emergency/screaming), with each level marked by distinct colors, icons, and descriptive labels such as whispering, 1-on-1 conversation, group discussion, outside voice, and emergency shouting. The diagonal line visually reinforces the escalation of sound intensity, making it ideal for educational or public settings where acoustic awareness is key. It supports behavioral guidance through visual cues rather than text-heavy instructions.
