Coded announcements can relay specific instructions in a structured manner, allowing individuals to respond appropriately without the need for loud or disruptive sounds that could disturb the environment or incite alarm among those who may already be anxious about the drill.

Selecting coded announcements acknowledges the unique challenges presented by nighttime drills, where visibility may be compromised and participants might be disoriented. These announcements can be pre-determined phrases or codes that communicate the nature of the drill and the necessary actions without the harshness of an audible alarm, which might be unsettling in a quieter, darker setting.
