1. A method of presenting sound to a user of a mixed reality environment, the method comprising:
determining a first location with respect to the mixed reality environment;
determining a first acoustic parameter associated with the first location;
determining a second location with respect to the mixed reality environment;
determining an acoustic relationship between the first location and the second location;
determining, based on the first acoustic parameter and the acoustic relationship, a transfer function;
detecting an audio event associated with the mixed reality environment, wherein the audio event is associated with a first audio signal;
applying the transfer function to the first audio signal to produce a second audio signal; and
presenting, to the user, a sound based on the second audio signal.
