The combustion impact energy acting to the inner wall of combustion chamber is transmitted through the engine structure and finally radiated from its surfaces as combustion noise. The frequency characteristics of engine structure response to the combustion impact were investigated by introducing a single explosion excitation to the non-running engine structures. The transmission-radiation coefficient of combustion noise was defined as a ratio of combustion noise power to the acoustic power exerted on the combustion chamber wall. This coefficient was compaired for four different types of engines.
