Background and moderate amounts of noise, surprisingly, can be tiring. An example of this are sounds typically prominent in airplanes. Although the mind works to automatically tune out background noise, the ears still hear it so the mind has to work harder to filter the sounds.

Feel refreshed at the end of a long flight by wearing noise canceling headphones during your journey. You’ll be amazed how rested you feel later. Noise canceling headphones are best used indoors though. Using them outdoors may have mixed results that might lower the headphones’ effectivity.
