It is a common thing that when sitting free, people will look around and observe things. Don't worry, they are not spying on you.
To solve this probelm, I recommend you to Occupy a window seat and turn the laptop a littile towards the window side. So, they can't see what you are doing.
To cancel noise, using a earphone with heavy sound will cause damage to your ear. So don't go for it.
To solve this problem, you should practice to avoid noise from surrounding. Personally I suggest you to practice YOGA to gain concentration.
