How do I get annoying kids behind me in a flight to shut up?

Firstly, make sure you are not making any sounds that could be annoying, such as snoring or tapping your feet. 
If that isn't sufficient, you could try to discreetly tell the flight attendant that there are too many noisy children in the back that are disturbing the rest of the passengers. If your flight attendant is understanding, they may be able to intervene and ask the parents to quiet their children. 
Finally, the last solution would be to headphones that are compatible with a device such as a tablet or a laptop. By having something to entertain you, you can more effectively tune out the noise from the back of the plane.
