We have the capacity for about 1.6 human conversations, so if you're listening to one conversation particularly, you're only left with 0.6 for your inner voice that helps you write.

It's dangerous to generalise about sound because many of its effects work through association. These can be universal: we all instinctively associate any sudden, unexpected noise with danger and react with a release of fight/flight hormones, while most people find sounds like gentle rainfall or birdsong calming and reassuring.

If you put music on top of noise, it's like putting icing on top of mud; it might look like a cake, but it doesn't taste like one.
