Sound Signals
Sound signals are audible warnings used by ships to communicate with each other and to indicate their presence, position, and intentions. These signals are an essential part of the International Regulations for Preventing Collisions at Sea (COLREGs) and are used in various situations such as when navigating in restricted visibility, when approaching other vessels, when anchoring, and when maneuvering in port. The sound signals are produced by various means such as whistles, horns, and bells, and their duration, frequency, and pattern are standardized. The use of sound signals is crucial for the safety of navigation and to avoid collisions at sea.
