The company I bought my mechanical keyboard from sells sets of O-rings that go under the key-caps[1] to reduce noise. They won't fit on every keyboard, but one could easily find different O-rings that do. I don't use them because noise isn't an issue in my situation, and I enjoy the sound of the key bottoming out. For those in open offices though, they might make the difference between tranquility and having your keyboard used as a doorstop(!)
