There are no plans to introduce the Australian N70 noise index at Heathrow. Aircraft noise exposure around Heathrow is quantified using noise contours based on the 16-hour Leg noise index. This index is based on significant scientific research correlating the Leq index with noise disturbance responses. No such correlation currently exists relating N70 contours with disturbance.
