"A 2013 study on mice published in the journal Brain, Structure and Function used differed types of noise and silence and monitored the effect the sound and silence had on the brains of the mice. The silence was intended to be the control in the study but what they found was surprising. The scientists discovered that when the mice were exposed to two hours of silence per day they developed new cells in the hippocampus. The hippocampus is a region of the brain associated with memory, emotion and learning."
"“We saw that silence is really helping the new generated cells to differentiate into neurons, and integrate into the system.”
In this sense silence can quite literally grow your brain. The brain is actively internalizing and evaluating information during silence." "The default mode helps you think about profound things in an imaginative way."
"Silence relieves stress and tension.
It has been found that noise can have a pronounced physical effect on our brains resulting in elevated levels of stress hormones. The sound waves reach the brain as electrical signals via the ear. The body reacts to these signals even if it is sleeping. It is thought that the amygdalae (located in the temporal lobes of the brain) which is associated with memory formation and emotion is activated and this causes a release of stress hormones. If you live in a consistently noisy environment that you are likely to experience chronically elevated levels of stress hormones.
A study that was published in 2002 in Psychological Science (Vol. 13, No. 9) examined the effects that the relocation of Munich’s airport had on children’s health and cognition. Gary W. Evans, a professor of human ecology at Cornell University notes that children who are exposed to noise develop a stress response that causes them to ignore the noise. What is of interest is that these children not only ignored harmful stimuli they also ignored stimuli that they should be paying attention to such as speech.
“This study is among the strongest, probably the most definitive proof that noise – even at levels that do not produce any hearing damage – causes stress and is harmful to humans,” Evans says.
Silence seems to have the opposite effect of the brain to noise. While noise may cause stress and tension silence releases tension in the brain and body. A study published in the journal Heart discovered that two minutes of silence can prove to be even more relaxing than listening to “relaxing” music. They based these findings of changes they noticed in blood pressure and blood circulation in the brain.
Silence replenishes our cognitive resources.
The effect that noise pollution can have on cognitive task performance has been extensively studied. It has been found that noise harms task performance at work and school. It can also be the cause of decreased motivation and an increase in error making. The cognitive functions most strongly affected by noise are reading attention, memory and problem solving."

Good article. Glad i found it.
The claim "Silence relieves stress and tension." seems to be true in my opinion. Back in my days as a math/stats student, I found that I came up with good solutions and made very good progress during silence or minimal noise. Libraries (with quiet areas) were effective in my experiences.
"Silence relieves stress and tension." could be a reason why meditation is effective.
Finally! A good backing when you tell someone to shut up. lol just kidding
For sure when working or trying to get things done though I need complete silence it is mostly why I stay up later at night to get things done.
