Its been long time since i posted. In recent month i have read more about ears and hearing loss then anything else. I still have issues with ringing that i am trying to fight with.
I would like to tell everyone to be cautions about high volume and playing with different sounds.
People are not educated enough about ear protection. It is so important.
I recommended to read:

Yeah, we went to Cancun in June. The resort had a great indoor theater stadium for nightly shows. But sometimes the sound level was excruciatingly loud to me. I had to use my ear pieces to protect by valuable ears from the extremely loud noise. I gave my daughter a set of ear piece too, which she used. She agreed with me that the noise level was too loud for her. I gave a set of ear piece to my wife. But like the majority of the audience, she chose NOT to use the ear pieces, saying the sound was NOT dangerously loud.
I looked around and I could not see anyone else covering their ears. Not the kids, not their parents.
I bet if they were at home, these people would not tolerate such loud volume. I measured the loudest level I could tolerate to be about 94dBC or about 85dBA in 2.0 mode. Although in 2.1, the loudest level was about 107dBC, but mostly due to the subwoofer. And that was the PEAK level, not constant level. Yet, my wife would quickly complain that it was too loud. I assured her that the 85dBA in my room was absolutely much less than the extremely noise level we heard in the Cancun theater stadium. But she brushed it off.
So I conclude that in public (theaters, concerts, dance, live events, etc.), people must be too embarrassed to cover their ears. They would rather endure the dangerous noise.
But certainly not I. If I don't have ear plugs or earphones, I will just use my 2 hands to cover my ears.
