Stick your fingers in your ears .
Wear ear plugs .
Put a long string on the flush handle and pull it when downstairs.
Put cistern outside .

Is it the syphon or ball valve if ball valve fit a torbeck valve reduces noise without the need to place fingers in ears.
You can also fit one of the new type flap valves for syphon these are operated by push button and are again much more quiet.
Both available from Plumbase
If it is flush noise you are trying to get rid of, rather than the cistern filling noise, you need to replace the pan, not the cistern. Syphonic types are much more quiet, and very common in the rest of the world. Some people hate them for leaving streaks, but they are very suitable for en-suites where you don't want to wake the other half (or half a dozen screaming kids down the corridor). Fit a decent quiet cistern valve to take away the filling noise and you have a very discreet system.

Several things to try:
Try turning down the isolator valve (if there is one) a bit to reduce/change flow rate.
Change the washer.
Replace ballcock with a Torbeck (tm) type. Remember to check that the overflow will handle the full flow from the valve held open though.
Personally I'd go for the last option.
OR adequate/additional pipe supports on the feed to the cistern; stops the resonance from the float valve as it nears fully closed. Easiest is to clean the valve. Worked for me.

In my experience trying to fasten the pipe better just makes things worse or simply changes the note and/or time it happens.
Going to that trouble one may as well change to a Torbeck(tm) type, apart from being far quieter they fill quicker as well.
