An introduction to aircraft noise lateral attenuation.
Abstract:ESDU 81035 gives guidance on the estimation of lateral attenuation of aircraft noise from noise measurements. Lateral attenuation is defined as the difference between the under-the-flightpath and sideline free-field levels where the propagation range of the two sound levels is the same. A knowledge of aircraft noise lateral attenuation is required for the evaluation of ground noise levels.
