Resumen:

Control strategies are considered for global reduction of tonal fan noise radiation in laptops. These strategies are studied through numerical simulation for global active noise control with compact arrays of sound sources distributed close to the fan. Error sensor arrangements are included for the detection of total acoustic power output. Multichannel adaptive algorithms are proposed for minimization of acoustic power in real-time DSP systems.
