Measurements are reported on sound transmitted through the walls of commonly used exhaust pipes under the actual running condition of a diesel engine. The sound levels and the spectral composition of transmitted sound are presented. Parameters such as type of joints, curvature of bend are investigated. Results of measurements are compared with those of previously conducted experiments using a loudspeaker as the sound source.
