Abstract
Devices, methods, and systems are described for an anti-feedback audio device () comprising a dipole speaker () having an acoustically null sound plane () or acoustically null sound area (), a first microphone () disposed substantially within the acoustically null sound plane () or acoustically null sound area (), and a neural network () communicatively coupled to the dipole speaker and the first microphone () such that a first output from the first microphone is communicated to the neural network () for processing, and a second output from the neural network () is communicated to the dipole speaker (). The combination of the dipole phase cancellation and the neural network gives an unexpected result of an extremely high signal-to-noise ratio for speech over noise.
