You do not know what you do not know. My father never wore any hearing protection. I copied him. I always used to shoot without hearing protection, because it was more comfortable not to do so. I was sure it didn't matter. Besides which, I was only firing a few shots, and that was spread out over a reasonable time period. My hearing is now very poor, and affecting my quality of life. Now, I always use hearing protection, whatever I am doing and no matter how few shots I may fire. It is too late for me, and I suspect, for many others of my age on this forum. Be wise and learn from the mistakes of fools ! ALWAYS use hearing protection.
