I've started visiting quiet rooms[1], just to hear myself think again. The world and the internet has become so loud that some quietness is refreshing. Luckily for me there are several where I live so I've even got a choice.

Strangely these rooms are quite different to being silent at home or somewhere else private. For me it seems to be that these spaces are public, you are being silent in public spaces - a different setting and experience than in places that are private. Being silent together can be disconcerting!

It's also different to using noise cancellation or listening to music or other forms of "silence", truly unique in many aspects.
