It does not use noise cancellation.

Does ChatterBlocker use noise cancellation?
No. Noise cancellation would not be effective over speakers, and noise cancelling headphones have limited effectiveness in silencing voice.
Good quality noise cancelling headphones are great for reducing low-frequency sounds, such as airplane engine rumble, but they are not as effective in the 2 to 8 kHz consonant range that conveys much of the speech intelligibility.
