How will people feel in a noisy environment?
In my opinion, it is hard to focus on what you are doing when it is noisy. So I think there is a conflict between your inner world and the outside world.
The inner world may on behalf of your thought and the outside world is how you feel physically. When it is quiet, people is easy to sink their own world and get a deep think. But the noisy environment push people to feel the outside world instead of concentrate on their thought.
I am going to divide a certain space into two parts. One present our inner world while the other one means the outside world. Since the space is certain, the two parts are going to strive for a larger room. If the environment is noisy, the part for outside will become bigger, while the inner part will become smaller and vice versa.
