During a recent cipher convention, a binary code contest took place. The contest consisted of a binary code transmission where the spaces between the letters were missing and there was no punctuation. Each letter of the alphabet was translated into its binary equivalent based on its position in the alphabet, a=1, b=10, c=11, d=100, e=101, f=110, g=111, h=1000, i=1001, j=1010, k=1011, l=1100, m=1101, n=1110, o=1111, p=10000, q=10001, r=10010, s=10011, t=10100, u=10101, v=10110, w=10111, x=11000, y=11001, z=11010.

If you run, you will need me,
If you live, you will breathe me.
When you climb a mountain,
I will start to disappear,
No matter how hard you listen,
No sound will enter your ear.
I'm a reason you're alive,
Without me you would surely die.
The way I come in is not the way I get out,
Another hint is that you use me more when you shout.
Without a helper I would not get in or out at all.

What am I, and what is my helper?
