Introduction:
Why is sound important?

Understanding the impact of unwanted noises in our everyday life.

We're always conscious of the environment around us


Imagine this: you're in the Stone Age. You just saw a beautiful, delicious gazelle. Your focus shifts completely towards your dinner. You're already looking forward to seeing your gorgeous stone age wife and tell her you caught food for days!

But then, you hear a lion roaring behind you.

Now, your focus on the gazelle doesn't seem so important, does it?

That's because our focus shifts every time we hear a voice or a loud sound.








But they don't make homo sapiens like they used to

The world has evolved in a way where lions don't show up in the middle of your office. That would be fun though.

We have this mechanism that is perfect for hunting and paying attention to sounds around us. However, A cellphone is the modern equivalent of a lion's roar.

When you hear a phone call, your brain processes it as possible danger.

This is inefficient for someone who wants to focus.







Sound distracts us and stresses us because we're biologically programmed to do just that.

But how does it affect us on the real, modern world?

Impact on health and wellbeing












Noise triggers the fight-or-flight stress response, releasing stress hormones like adrenaline and cortisol.


When these hormones are out of the picture, so is stress.









Environments that support health and wellbeing create positive outcomes.



A growing body of research indicates that spending time in quiet environments helps to lower stress and blood pressure levels, decrease fatigue, enable brain restoration, and promote healing.











Impact on productivity











Ringing phones and nearby conversations can affect your concentration and performance
