Since combustion noise is generated by the fluctuation of heat release due to turbulent flows, its acoustic characteristics may be affected by the kind of fuel used. In the present study, using gaseous fuels of methane, ethylene, propylene and propane, the acoustic characteristics of associated combustion noise is studied experimentally. As the results, it is shown that the effects of the flow velocity, the equivalence ratio and the turbulence intensity of the mixture on the noise intensity are little affected by the kind of fuel and also the magnitude of the inherent burning velocity affects the noise intensity level of premixed flames.
