Whistled languages are unique forms of communication that use whistles to convey messages, often mimicking the sounds of spoken language. These languages are typically found in mountainous or remote regions where vocal communication can be difficult over long distances. They allow speakers to communicate effectively without the need for shouting. One well-known example of a whistled language is Silbo Gomero, used by the inhabitants of La Gomera, one of the Canary Islands. This language can transmit complex ideas and information, making it a valuable tool for farmers and shepherds in the rugged terrain.
