I rather enjoy not having ringing ears after shooting while hunting. But that's because 1) I have cans and 2) i also rather enjoy hearing the woods while I hunt and can't be bothered with limiting my hearing.
The animals have much better senses. No reason we should have to further limit our already limited senses because of bureaucratic BS.
That's where electronic muffs come in handy. If you get the right ones, you will actually be able to improve your ability to hear as well as providing hearing protection.
