My suggestion is that if you shoot raw or raw+jpeg then examining the raw files (with something like RawDigger) is the real "scientific" approach, otherwise the tone curve hopelessly muddles the results.

The problem here is that there is no clear notion what noise is, what we want to measure about it, not to mention how to measure it.
