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 18):
A sound externalization system, comprising:\n a headphone assembly worn by a user; a sensor configured to detect an acoustically reflective surface in an environment in which the user is located; a controller configured to:\n associate a first location in the environment with a virtual sound source; \n determine a second location of the user; \n determine reflected sound path simulating sound from the first location to the user that includes a reflection by the acoustically reflective surface at a third location; \n generate a first head related transfer function simulating characteristics of sound traveling from the first location to the second location; \n generate a second head related transfer function simulating characteristics of sound traveling from the third location to the second location, wherein the second head related transfer function is different from the first head related transfer function; \n generate a sound signal for the virtual sound source; \n generate a first output signal by filtering the sound signal with the first head related transfer function and a second output signal by filtering the sound signal with the second head related transfer function; and \n a speaker of the headphone assembly configured to produce sound in accordance with the first and second output signals.
