What kind of instructions were non-vocal signals like bells or bugles exceptionally good at conveying?
Answer
Urgent, simple commands such as "Assemble," "Danger," or "End of meeting."
Non-vocal signaling methods, including the use of bugles, horns, or large bells, serve a crucial function when human speech becomes unreliable due to extreme distance or overwhelming noise. These signals are not capable of conveying complex, nuanced verbal instructions, which is where the voice excels. Instead, their utility lies in their sharp, distinct auditory nature, which allows them to cut through significant interference in chaotic environments like construction sites or rescue efforts. They are optimized for conveying simple, universally understood, time-sensitive directives that demand immediate attention, such as alerts for danger or calls to assemble.
