Homonym: Dog Whistle (Politics)
A "dog whistle" is a type of whistle that emits a sound at a frequency that is inaudible to humans but can be heard by dogs. This tool is often used in training and communication with dogs, allowing trainers to give commands without disturbing people nearby. The high-pitched sound typically ranges from 18,000 to 22,000 hertz.
In a broader context, the term "dog whistle" is also used metaphorically in politics and social discourse. It refers to coded language or phrases that convey a specific message to a particular group while remaining ambiguous to others. This allows speakers to communicate controversial ideas without overtly stating them.
