Abstract Learning from the successful application of the sound absorption seats in the music halls and theaters and also based on the features of the noise spectrum in high speed trains a sound absorption seat design which applies specifically to the high-speed trains is put forward in this paper. High performance absorbing materials and perforated plates are selected and designed. Finally, seats of full train carriage were made and tested in the high-speed train on the railway. The test results showed that the installation of the sound absorption seats results in the noise level at the standard point in the passenger compartment decreases by 1.5 dB compared with that of the normal seats.
