1. A method of presenting sound to a user of a mixed reality environment, the method comprising:
determining a first location of the user with respect to the mixed reality environment;
in response to determining the first location, accessing, from a memory, a transfer function, the transfer function based on a first acoustic parameter associated with a first location and further based on an acoustic relationship between the first location and a second location with respect to the mixed reality environment;
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.
