Conventional audio-integrated feedback active noise control (ANC) systems use single rate to process low rate noise signal and high rate audio signal, which degrades the performances of both ANC and audio systems. This paper presents multirate audio-integrated feedback ANC system to admit the different sampling frequency in both ANC and audio system based on interpolation and decimation techniques...
Have you ever faced a situation where you really wanted to enjoy your favorite music in a very noisy environment? To overcome this problem, you can either block the noise or increase the music level to mask the annoying sounds. This begets the question, "Is there a better solution?" In recent years, the technology industry has grown enormously, especially in the areas of smart, mobile, and...
This paper presents the active noise control (ANC) systems for creating quiet zone to cover the users' ears in headrests. The two-input two-output (TITO) ANC headrest system based on the multiple-channel adaptive feedback filtered-x least mean square (FXLMS) algorithm is proposed. In order to reduce system cost of the TITO ANC headrest system, the combined-input combined-output (CICO) ANC headrest...
This paper presents audio-integrated snore active noise control (ANC) systems based on the portable pillow setup to effectively reduce the annoying snore and mask the residual noise. Computer simulations and real-time experiments show the performance of the ANC systems based on the pillow setup achieved higher noise reduction at the ears of the snorer's bed partner as compared with the headboard setup...
