Sound signals are auditory cues used to convey information or instructions. They can be produced by various devices, such as horns, whistles, or sirens, and are commonly used in transportation, emergency situations, and communication. These signals help ensure safety and coordination in environments like roads, air traffic, and maritime navigation. In many cases, sound signals follow specific patterns or codes to indicate different meanings. For example, in maritime contexts, a series of short blasts from a ship's horn may signal a warning, while a long blast can indicate a vessel's presence. Understanding these signals is crucial for effective communication and safety in various settings.
