I have electronic muffs, the brand that many swat units use, Radians, and sport ear electronic gar plugs. They both work fine, until there is wind, then you get a very distracting noise from the wind bowing over the place that sound gets in. I usually got to wearing one sonic, the kind with the metal canister on the one end and deeply ribbed rubber on the end that goes into your ears. If it looks like I am going to get a shot I put the other one in. I have tinitus, my ears hiss 24/7 except when I drink whisky or a martini, then it stops for a couple of hours. Seems to me that if imbibing alcohol stops the noise, some pharmaceutical company could develop a pill that would have the same affect.
