Systems and methods for adaptive additive sound

A system for adaptive additive sound, comprising:

• a first plurality of microphones distributed within a first zone;
• a first speaker positioned within the first zone;
• a second plurality of microphones distributed within a second zone that is spaced from the first zone;
• a second speaker positioned within the second zone;
• one or more processors;
• and
• one or more non-transitory computer-readable media that store instructions that, when executed by the one or more processors, cause the system to perform operations, the operations comprising
• receiving ambient sound data corresponding to ambient sound in the first zone from the first plurality of microphones,
• analyzing the ambient sound data from the first zone in order to determine a spectral balance of the ambient sound of the first zone in a plurality of octave bands,
• generating pink noise data for the second zone corresponding to pink noise such that a spectral balance of the pink noise in the plurality of octave bands is correlated to the spectral balance of the ambient sound of the first zone in the plurality of octave bands,
• generating audio signal data for the second zone based at least in part on the ambient sound data from the first zone, the audio signal data for the second zone comprising delayed ambient sound data from the first zone, the pink noise data for the second zone, and natural noise data corresponding to natural sounds, and
• transmitting the audio signal data for the second zone to the second speaker.
