Noise ..... What noise
Having grown up in Cranford (~ 1 mile back from the threshold of what was then 28R) in the era of B707, DC8, VC10, Conc etc. I know what noise is! I occasionally go back to the Cranford area and the noise level is so much lower these days, so I would suggest that the overall disruption to life is far less now than it was 30 - 40 years ago; however if you move from an area with no aircraft to the Heathrow area then of course there will be more noise than you are used to, but it was your choice to move.
