Homonym: Dog Whistles (Politics)
A "dog whistle" is a type of whistle that emits sound at a frequency that is inaudible to humans but can be heard by dogs and other animals. These whistles are often used in training, as they allow trainers to communicate commands without disturbing people nearby. The sound typically ranges from 23,000 to 54,000 Hz, which is well above the human hearing range.
In a broader context, the term "dog whistle" is also used metaphorically in politics and social discussions. It refers to coded language or phrases that convey a specific message to a particular group while remaining ambiguous to the general public. This allows speakers to communicate controversial ideas without overtly stating them, often appealing to certain ideologies or beliefs.
