The paper presents a laboratory system for testing active control algorithms of acoustics noise in ducts. An applied algorithm - self-optimizing narrowband interference canceller (SONIC), allows one to remove narrowband disturbances of constant or slowly time-varying frequencies. Example experimental results of using the laboratory system for supression of sinusoidal disturbance are described. An electronic part of the system was made using a digital signal processor (DSP) starter kit (DSK) of the TMS320C6713 signal processor. This approach is a base for future works on designing a laboratory system for testing active control algorithms of acoustic noise in heating, ventilating, air conditioning (HVAC) or exhaust ducts.
