💨💨 FAN SOUND FOR SLEEPING 💨💨

Keep the sound of a fan for company
To study, relax and even sleep
Also known as white noise.
This sound makes the hearing ability
Reach your maximum level, that is,

When we're in the presence of that kind of sound
Other louder noises have less capacity
To activate the cerebral cortex during sleep.
Therefore, it works as a true wall of sound energy.
Protecting our ears from distractions.
