Abstract:
A system and method for externalizing sound. The system includes a headphone assembly and a localizer configured to collect information related to a location of the user and of an acoustically reflective surface in the environment. A controller is configured to determine a location of a virtual sound source, and generate head related transfer functions that simulate characteristics of sound from the virtual sound source directly to the user and to the user via a reflection by the reflective surface. A signal processing assembly is configured to create one or more output signals by filtering the sound signal respectively with the HRTFs. Each speaker of the headphone assembly is configured to produce sound in accordance with the output signal.

Claim (Index 19):
A method for externalizing sound from a headphone assembly worn by a user, comprising:\n associating a virtual sound source with a physical location in an environment in which the user is located; identifying one or more acoustically reflective surfaces in the environment; determining a reflected sound path from the physical location to the user that includes a reflection by the acoustically reflective surface; generating a first head related transfer function (HRTF) simulating characteristics of sound received by the user directly from the physical location; generating a second HRTF simulating characteristics of sound received by the user from the reflection, wherein the second HRTF is different from the first HRTF; generating a sound signal corresponding to the virtual sound source; filtering the sound signal with the first HRTF to generate a first output signal; filtering the sound signal with the second HRTF to generate a second output signal; and producing sound with a speaker of the headphone assembly in accordance with the first and second output signals.
