Abstract: | An improvement appears to be possible in estimating UK aircraft noise annoyance. This is based on a more detailed analysis and modelling of the data supporting the present UK aircraft noise policies. There is empirical evidence that people’s real-life annoyance at aircraft noise is in part determined by its time-patterns. People benefit from Heathrow’s regular and predictable alternation cycles on westerly operations, equivalent to an effective dB(A) Leq value for that operational mode some 2-dB less than the measured dB(A) Leq. This correction is statistically controlled for people whose work/business is connected with Heathrow. The implications of a time-pattern correction would be significant for UK airport noise contours. |
