If you don’t want to invest in a white noise machine, there are several white noise YouTube videos
you can play to help you to block out noise and fall asleep.
The second option is better suited for those who need complete silence to be able to fall asleep.
Believe it or not, a simple pair of earplugs
will work perfectly to counter noise pollution.
Earplugs are usually a much more affordable option than white noise machines, and are also a practical choice for those who often sleep in transit or take power naps outside their home environment (after all, you can’t exactly bring your white noise machine with you on the airplane.)
They work by safely expanding in your ear canal and completely sealing it off, so that sound can’t hit your eardrum and wake you up. They’re comfortable, and chances are that once you get used to them, you won’t feel them at all.
If you’re concerned that you’ll sleep through your alarm with earplugs in, invest in a vibrating alarm clock. Many earplug devotees also set their coffee pot timers in the morning, so the pleasant smell of that morning cup of joe wakes them up.
