The large number of cross circuits because of strip use spreads the noise footprint over a much larger area than a conventional airfield. This also has the effect of diluting the noise in the undershoot of the main runway. The noise has also decreased recently with the 1(F) move to cottesmore (although the Navy are making up for that somewhat). This house is so far out that most circuits turn comfortably inside it anyway and anyone who does fly over it is flying bomber circuits and deserves to be chopped anyway. Solution - put 75' and 150' rings round it and use it as a crv7 target.
