Method is developed to compute noise in vicinity of starting aircraft; with knowledge of aircraft data and climb path data sound level decibel is calculated for distances up to 10,000 m from flight path of turbojet and propeller aircraft; width of equal-noise contours is calculated; equations have been coded for computer-processing; calculation method for turbojet aircraft has been checked by flight noise measurements; flight noise measurements have also been performed in military turbojet aircraft and in propeller driven transport airplanes.
