Interesting idea. Basically, it recreates the noise of a coffee shop:
the mix of calm and commotion in an environment like a coffee house is proven to be just what you need to get those creative juices flowing.
Personally though, I can’t stand noisy environments to work in. I remember asking other designers on Twitter, a little while ago, what they preferred and the vast majority of them said peace and quiet.
I don’t mind some ambient noise now and again but the real problem I find with this, is it’s hard to ignore that it’s just an illusion. The real benefit of working in a coffee shop is the people. Even if you don’t interact with anyone, you don’t want to be just browsing the web, you want everyone to know you’re working hard and you can’t recreate that with some noise.
