Active Control of Interior Noise in a Fork-Lift Truck

• Modern fork-lift trucks incorporate a wide range of sophisticated passive techniques to reduce the noise inside the cabin. By using a combination of passive and active noise control technologies it may be possible to further reduce the noise level, thereby improving the comfort for the truck driver. The purpose of the work presented in this paper is to examine whether it is possible to reduce the low-frequency cabin noise by using active noise control technology. The noise situation inside the truck cabin is discussed as well as the active noise control strategy for a practical fork-lift truck installation. The paper presents sound field plots of the cabin noise and preliminary active noise control results from computer experiments based on recorded cabin noise.
