Hang a pair of these excellent safety devices around your neck in the field and when you start whistling, calling or spotlighting, you just remember to stick them in your ears.
Without any electronics or batteries, these miraculous pieces of plastic attenuate 26 decibels of sound from loud noise, while allowing normal conversation. They weigh next to nothing and provide more protection than a regular pair of electronic earmuffs, which typically attenuate 21-23 decibels.
