The survival whistle is not an ordinary whistle. People think that the general whistle can be used as a whistle for survival. This idea is very wrong. A whistle must be able to play the role of a helpless person. The sound it emits must meet a temperature of 3,000 Hz. Why it is 3,000 Hz, because the human ear is very sensitive to the 3,000-Hz sound. So the survival whistle is a whistle capable of emitting a 3,000-Hz sound. Survival whistle does not have to be used when in distress. It can be used as a contact, simple communication and orientation, or where to help, and so on. You can use it to communicate when there is a situation, especially in the summer when the visibility is low in the woods, green gauze, corn fields, and the night. Using the whistle correctly will help you get more protection in outdoor sports. When there is no thing, please do not blow the whistle.
