Oh yes. Sound Barrier ear muffs are what I bought back in the 1970's to protect my ears while target practicing with a fire arm. They look like those light green headphones that you see pilots wearing on TV.
I forgot where I bought them. I probably bought them at a Pistol,and Rifle sports store.
When you put them on,you don't hear very much. They are much,much better then ear plugs. Mine are more then 30 years old,and when I put them on,I have silence,except if my left ear is ringing from the seroquel.
