The range of the survival whistle:

A survival whistle does not necessarily have to be used in emergencies, such as greeting those in front or behind, determining the distance, and determining the direction of the sound source, and so on. However, there is a problem here. Sometimes, when climbing a mountain, one might just feel like blowing the whistle, and if one does it too often, others may not feel anything special about it. If they hear someone else blowing, they may not feel like blowing themselves, and they may continue on their own. In this case, if someone twists their ankle or needs help, or if a new hiker who is far away from the group gets lost at an intersection, it is very urgent to have no response to the whistle blowing, because the others might think nothing has happened. They are busy silently pulling the cart, and they don't have much time to pay attention to it. It's like the story of "The Wolf Came."
