An acoustic metamaterial (1400) including cells (1402) to digitally process an incoming sound waveform (1404), and to produce a corresponding response sound waveform (1406) as a function of a frequency and a phase of the incoming sound waveform, to produce a total response sound waveform (1408) that, when combined with the incoming sound waveform, modifies the incoming sound waveform. |
