1. A method for adaptive additive sound, comprising:
receiving ambient sound data corresponding to ambient sound in a first zone acquired by a microphone in the first zone;
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 a 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 a speaker in the second zone,
wherein the first zone is separate from the second zone within a space.
