We live in a noisy world.
And we always try to make sound barrier. With the earphones and our own music station. We distant ourselves with the crowd. The sources of whole other noises. The sound of tickling clock, dripping water, stopping car, walking people. As we left the world to other dimension, we might forget that we still step on one.
Cocktail Party effect is the ability to let your ear focused on a single voice in a room full of background noises. It’s the same with every other things, you only want to hear what you want to hear.
It makes sense.
The only silence you’ll ever got, it’s the loneliest time you’ll ever had.
