Why is it possible that one could still hear when the ears are carefully covered?

I tried covering my ears because of noise, I noticed I still hear the noise though faintly, why?

Again I was in a public vehicle and the breeze outside was thick and stiff that it almost spoil my ear because I sat close to the window I had to cover it with my hands yet I could still hear things somehow.

Does it mean one can't cover his ears so as not to hear again?

You can. Use a long pin and puncture your ear drum. Problem solved.


You know the say "modern problems require modern solutions"
