Cockpit Noise Analysis in a Small Training Aircraft

Cabin noise in a small training aircraft is an important factor that affects not only the quality of cockpit speech communication, but the human health as well. Training aircraft make a large number of operations in one day and are distinguished from transport aircraft by a large number of takeoffs and landings. Since the noise is much higher during such operation regimes than during the cruising, the instructor and the student can become fatigued thus endangering the safety of flight. Unlike the external noise that is precisely defined and standardized through international regulations, aircraft internal noise has not yet been particularly standardized. The results of the cabin noise measurements within piston engine training aircraft Diamond DV20, both in various operating conditions during the flight, as well as in typical power settings on the ground, is presented and discussed in this paper. Furthermore, a few possible methods of noise reduction will be shown.
