We all want to spend time in a quiet and silent place to escape from all the madness going on in our lives. And according to you a quiet place would be the one where there are no or less people, you hear the sound of the rustling leaves and breathe in fresh air. No, we ain’t talking about that. We are talking about anechoic chambers, which are so quiet that you will be able to hear the voice of blood flowing through your arteries and veins. Excited?
