I agree with you PAXboy, having lived under the north, west and now southerly tracks. For those currently under flight paths, things will improve overnight if/when R3 opens as more or less the same traffic will be distributed over 3 areas and not 2. There will not suddenly be a 50pc increase in demand.
By the time the runway fills up, at the current rate of progress, aircraft will be virtually silent. People are judging this by historic standards and the airport
PR machine is very poor in this respect. An A380 rotated next to my car the other night and in no way could the noise be considered at nuisance value. Similarly a 787 on final approach is almost literally silent any more than a couple of hundred yards away. Any doubters can hear for themselves in any of the local pub car parks.
