Noise Pollution
Many studies link noise pollution to:
- High blood pressure
- Sleep loss
- Heart disease
Just as noise pollution is bad for you, silence can actually benefit your brain.

Self-Reflection
When there is no outside noise, simulation or distraction, the brain starts to go inwards, getting into the self-reflection mode.

Seeking silence
Silence relieves tension
Noise pollution may lead to high blood pressure and heart attacks, as well as impairing hearing and overall health. Loud noises raise stress levels by activating the brain’s amygdala and causing the release of the stress hormone cortisol, according to research.
Silence has the opposite effect, releasing tension in the brain and body.
Silence and our mental resources
The constant attentional demands of modern life put a significant burden on the prefrontal cortex of the brain, which is involved in high-order thinking, decision-making and problem-solving.
When we can finally get away from these sonic disruptions, our brains’ attention centers have the opportunity to restore themselves.

Noise is bad for health
It increases blood pressure, increases stress, disturbs our sleep.
And more importantly, it is linked to our bad mental health. It's why we don't have schools in the vicinity of airport...

"In most workplaces, focused work is left to chance.If nobody's called you for a meeting that day, you might get an afternoon to yourself."
Silence for relaxation
Silence is more relaxing than relaxing music.
In an experiment, the silence was used as a control between the different relaxing music clips. But the two-minute silent pauses between the music actually proved more relaxing on the brain.

Binaural beats
Binaural beats are an auditory illusion that has stress-busing properties. Proponents claim that listening to binaural beats can boost focus, promote relaxation, and reduce stress and anxie...
Explaining binaural beats
- Binaural beats is a perceptual illusion that happens when two slightly different frequencies (notes) are played into each ear separately, usually using headphones.
- The resonance between the two frequencies is interpreted as a third sound - or binaural beat - and is heard as a frequency between the two played frequencies.
- The claim is that this third frequency prompts brain cells to begin firing at the same frequency, which purportedly is similar to the frequency of brain waves that occur during deep sleep at our most relaxed states.
Different types of brain waves
Specific frequencies are thought to be involved in specific cognitive tasks.
- During deep sleep, the predominant brain activity occurs with frequencies between 1 and 4 Hertz (delta waves.) Delta waves are associated with learning and motivation.
- Theta waves (4-7Hz) are linked to memory and emotional regulation.
Brain entrainment - where brain cells fire at the same frequency - is a real effect that happens in response to particular rhythmic frequencies perceived by our senses. A deep-pitched musical tone can cause your brain cells to start firing at the same frequency.
