I was out today with the shotgun wearing my electronic ear defenders. These amplify the sounds around me and whilst I can hear the wildlife a lot clearer it also dawned on me that I could hear myself a lot clearer. I spent the rest of the afternoon trying to move even slower and quieter listening to the noises I was making.
Possibly a very useful training aid for stalkers?
I may start wearing them for stalking in the winter months anyway, not only to remind me that I am not as quiet as my normal hearing suggests I am, but also to keep my lugs warm whilst not blocking out sound. :-)
