You can, and should put your phone into airplane mode, or turn it off when studying. You must be aware the hearing the Facebook message beep is going to leave you wondering who it is and what they want. You will not work efficiently until you stop working and look at the message! So no noise from your cell phone now, that’s going to help a lot. But what about noise we can’t control?
Neighbors shouting, Traffic noise and TV from the next room, these are all things that are not so easy to control. So what can you do about those distractions from the environment? Get ear muffs for studying, or other times you just want some quiet, maybe when trying to sleep?
