Quick Answer
To attract attention while lost, use sound to alert potential rescuers by making loud, repetitive noises, such as whistling, shouting, or banging objects, for at least 30 minutes at a time, and change locations every 30 minutes to stay visible.
Shouting Techniques
When shouting to attract attention, use a loud, clear voice, and speak in short sentences or phrases, such as “Help!” or “I’m over here!” Repeat this every 30 seconds to 1 minute to maintain a consistent signal. Aim for a volume of at least 100 decibels, which is equivalent to a chainsaw or a lawnmower.
Object Banging and Whistling
Banging two objects together, like rocks or sticks, can also be an effective way to create loud noises. Alternatively, use a whistle, such as the classic pea-less whistle, which can reach distances of up to 1 mile. To maximize visibility, bang or whistle while standing near a recognizable landmark, such as a tree or a rock outcropping.
Changing Locations and Staying Visible
To stay visible to potential rescuers, change locations every 30 minutes to 1 hour. This can be as simple as moving to a nearby ridge or hilltop. Always aim to stay in an area with good visibility, such as an open meadow or a clearing. This will increase the chances of being spotted by rescue teams or other hikers.
