These are the audio-mic USB adaptors which allow two mic inputs at the same time.
The picture shown on the left is the experiment setup. The microphone in the far left corner measures the noise and the microphone on the right measures the primary input, which is the corrupted source. The speakers that play the noise must be the same set and the  two microphones must stay ceratin distance.
The real time adaptive noise cancellation is not so different from the second demo "Field Measurement" except that the the Simulink module is used as the vector concatenation and communication interface between the source and the FPGA.
