How far can dragons hear things?

The ability of dragons to hear sounds varies widely depending on the mythology or fantasy setting in which they exist. Generally, dragons are depicted as having keen senses, allowing them to hear sounds from great distances, often several miles away. This heightened sense of hearing is typically attributed to their size and magical nature, enabling them to detect even the faintest noises in their surroundings. However, specific distances are rarely quantified in literature, leaving it largely to the imagination.
