This report covers noise measurements on a representative pusher-type amphibian airplane. The work supplements earlier work by the Aeronautical Research Foundation on the external noise of tractor-type airplanes. Modifications of the pusher-type airplane and noise-measurement procedures used for the present work were similar to those used for the earlier noise study of the tractor-type airplane.
