Nonlinear active noise control (ANC) algorithms are used to control nonlinear noise processes. In this paper, a generalized filter bank based nonlinear ANC algorithm is proposed for active headrest application. The algorithm is used to control the noise at both ears by using two moving error microphones which are mounted on the head. Mounting of microphones can be made using a wearing item such as...
Design and implementation of active headrest are having challenges as the performance of noise reduction at the ear reduces due to head movement. In this paper, an active headrest is implemented using two secondary loudspeakers and two error microphones using a multi-channel active noise control (ANC) algorithm running on a dSpace dS1104 platform. The performance of an active headrest was studied...
