AB  - Active noise control was implemented using loudspeakers embedded in the headrests of two adjacent seats. The goal of this study was to create a quiet zone surrounded by headrest 1 which was free from noise caused by the adjacent loudspeaker mounted in the next-to headrest 2. While Headrest 1 was generating noise, headrest 2 was designed to cancel out noise that was being generated by headrest 1, by driving the anti-noise signal through the loundspeaker, without using earphones/headphones. Control source, the speaker of Headrest 1 generating anti-noise, was made from FIR convolution with the electrical signal going to the primary source, the speaker of headset 2 generating target-noise. Implementing both primary and control sources results in a 20-30 dB noise reduction throughout the targeted frequency range (2kHz and below) in terms of squared acoustic pressure.
