11. Marpac Sound Machine
Sound greatly affects the way you sleep. Whether you live close to a busy street or an apartment over from someone who watches loud TV late at night, the slightest noise can wake you from a deep sleep. Research shows that the best sleep takes place when sound falls under 30dB (decibels) and that anything over this number, even subtle noises like bird chirps and whispering voices, can disrupt your sleep. The Marpac Sound Machine blocks out external disturbances with white noise. Yes, you heard right, white noise—that sound the TV made when the satellite couldn’t pick up the channel’s signal. Sound machines are the perfect solution for people living in cities or with snoring partners. They emit consistent, soothing noises, often in a variety of sounds along with white noise, to help you tune in to sleep mode and tune out the rest of the world.
