Active noise-control system with source-separated reference signal

An active noise cancellation system, comprising:

• a first microphone that generates an electronic reference signal in response to a first acoustic input from a first sound source and a second acoustic input from a second sound source;
• at least one memory that stores a source separation algorithm;
• at least one processor that is coupled to the at least one memory and, when executing the source separation algorithm, is configured to:
• receive the electronic reference signal,
• based on the electronic reference signal and on a database of recorded sound signatures stored in the at least one memory, selecting a portion of the first acoustic input as a separated signal,
• modify the separated signal based on at least one of the recorded sound signatures to generate a source-separated reference signal, and
• generate an electronic correction signal;
• and
• a second microphone that generates an error signal in response to acoustic inputs.

A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform the steps of:

• receiving an electronic reference signal from one or more microphones that receives a first acoustic input from a first sound source and a second acoustic input from a second sound source;
• based on the electronic reference signal and on a database of recorded sound signatures, selecting a portion of the first acoustic input as a separated signal;
• modifying the separated signal based on at least one of the recorded sound signatures to generate a source-separated reference signal;
• and
• generating an electronic correction signal based on the source-separated reference signal.
