How sound affects your sleep

How does sound affect your sleep?

We all know it: you settle in for a good night’s sleep, and then the noise starts. The neighbour’s party, a car gunning its engine, or maybe a dog barking somewhere in the distance.

In fact, over 70% of us wake up at least once during the night because of noise — and that can have bigger consequences for your sleep than you might think.

We’re particularly vulnerable during REM sleep, when the brain is most active and we dream. A sudden sound can easily pull us out of sleep.

And even if you don’t fully wake up, even small interruptions can lead to lower sleep quality — leaving you tired and unfocused the next day.

When does sound become a problem?

By comparison, a whisper is about 30 dB, normal conversation is around 60 dB, and traffic noise can reach 80 dB. The louder and more unpredictable the sound, the more likely it is to disrupt your sleep.

Interestingly, our brain can still react to changes in sound levels during sleep. Research shows that even if we don’t fully wake up, unpredictable noise can affect sleep depth and lead to less restorative sleep.

Why continuous noise can be less disruptive

It might sound strange, but constant background noise can actually be less disruptive than sudden sounds. The brain quickly habituates to predictable, even sound — which is why so many people use white noise as a backdrop for sleep. It creates a stable layer of sound that can mask more disruptive noises.

SleepDeep or SleepSoft — which suits you?

If you want maximum noise reduction, SleepDeep earplugs are perfect. They block most of the noise around you and ensure deep sleep — even in a noisy environment.

If, on the other hand, you’d still like to hear a little — like an alarm clock or your child calling — SleepSoft earplugs are the ideal solution. They dampen sound enough to give you peace, while still letting the most important sounds through.

Whichever you choose, the right pair of earplugs can make the difference between a night of broken, shallow sleep and the deep, undisturbed rest your body actually needs.
