Regulations on the Use of Survival Whistles [Repost]"]

A survival whistle does not necessarily have to be used in emergencies, such as to greet those in front or behind, to determine the distance, and to determine the direction of the sound source, and so on and so forth. 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, everyone gets used to it and stops responding when they hear others blowing. They go about their own business, and if one of them 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 one respond to the whistle because the others might think nothing has happened. They are busy silently toiling, and they don't have the time or energy to pay attention to it. It's like the story of "The Wolf Came."
