Design of a quiet-comfort headboard

This paper presents the design of quiet-comfort headboard that uses an active noise control (ANC) system to reduce low-frequency environmental and snoring noises, thus enables the consumers to sleep in a serene environment. The ANC system uses adaptive feedback ANC algorithm with error microphones and loudspeakers mounted on the headboard. MATLAB simulations using the measured transfer functions from the experimental setup are used for designing adaptive algorithm. Real-time experiments using a floating-point digital signal processor demonstrate the designed headboard is effective for reducing snore and other undesired noises.
