Abstract: Modern fork-lift trucks incorporate a wide range of sophisticated passive techniques to reduce the noise inside the cabin. By the use of active noise control technologies it may be possible to even further reduce the noise level in total but also to attenuate certain tonal components, thereby improving the comfort for the truck driver. The paper discusses the noise situation inside the truck cabin as well as the active noise control strategy for a practical fork-lift truck installation. A feedforward control approach is used, along with several possible reference signals, forming a multiple reference controller.
