Authors: Young Min Kim, Jong Il Bae, Kwon Soon Lee
Abstract
In this paper, the high speed train interior noise reduction performance of the multi-channel ANC system was evaluated. A 1x2x2 multi-channel ANC algorithm was used for this purpose because high speed train interior noise has various noise sources. Experiments were carried out at two positions in floor, using pure-tone noise, to find the optimal positions of the control speakers and error microphones. At the selected optimal position, an ANC system performance evaluation experiment was carried out at variable heights, using high speed train interior noise. As a experiment result, the active noise control system shown good performance in the near position and high position from primary noise.
