Production Integration of Active Noise Control Systems in Working Locomotives - Challenges and Benefits 2011-01-1640

Active noise control (ANC) has been established as an effective way of addressing low frequency tonal noise in a weight-effective manner. The noise signature of a diesel locomotive cabin suggests that it is a good candidate for ANC. While often true, the production integration of ANC in a working locomotive has challenges extending well beyond laboratory demonstrations. This paper describes an ANC product developed as an aftermarket treatment for a particular model of fleet locomotive including locomotive passive treatment needs, control methods motivated by cabin acoustics, space and safety requirements, as well as logistical demands for testing and deployment.
