View Full Version : The 'ringing' in my ears?

Wait - this isn't going where you think, so get ready to drop the lecture on ear protection.

I go to the carbine match today in San Antonio, I see some other p-f members but didn't get a chance to say hi. I shoot with my squad of friends. I shoot decently at my sloth like pace. The gun runs well. We all go to lunch at a great mom and pop Mexican restaurant. I recommend it. Papa Gallo's on 281 just south of the exit to 1863.

Anyway, I get home and go into the garage to get out of my stinky clothes and I start to ear some fluttering, tweety sounds. At first I think it is a cricket but it follows me into the house. My wife doesn't hear. I go upstairs and I still hear it and it goes on and off and fluctuates.

Damn, I have screwed my ears even with muffs and plugs. Oh, my God. It's still there. Ok, I start to unpack the gun bag and take out the electronic muffs. The sound is loud. The two ear pieces of the muffs are together. I separate them as I take them out of the bag and the sound stops. Guess what, I didn't turn them off. I thought I did but you have to hold the power button down and I didn't do it long enough. When together, they were feeding back and making the sound. Phew!!! That was a weird one.

Now, if I would stop seeing the red glowing circle with a dot in it, I'll be ok (just kidding). Fun stuff on our squad - one guy was shooting an old bolt action Mosin-Nagant. You have to make one head shot with a bolt gun and he did. Neat to see. He did it for fun.

Are they sordins? Mine will make some aweful noises if I put them together while
They are on.

Yeah, I hear that kind of stuff all day every day, along with a jet engine, a smoke detector, and a hissing sound. Glad it's not the case with you though!

They were MSA muffs. It was so weird for awhile.

Yeah, my Sordins do that.

Found a decent explanation here:

I've had this happen sometimes at work, when we were working with a customer's ANR (active noise reduction) helmets for a simulator. You have to distance the speaker from the mic, or insert something inert (I use my head -- *rim shot* :cool:) between.

I thought it was all about heterodyning signals and feedback. Something I vaguely remember from many, many moons ago.

Could be worse. Set your bag down in Vegas and the nearest scorpion will make a beeline for it!

An outgoing mortar a foot from my head, without ear pro, did it for me!
