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 1):
A sound externalization system, comprising:\n a localizer configured to collect information related to a first location of a user in an environment and a second location of an acoustically reflective surface in the environment; a controller configured to:\n determine a third location of a virtual sound source in the environment; \n generate a first left head related transfer function (HRTF) and a first right HRTF that simulate characteristics of sound radiated from the virtual sound source directly to the user; \n determine a reflected sound path from the virtual sound source to the user that includes reflection of sound by the acoustically reflective surface; \n generate a second left HRTF and a second right HRTF that simulates characteristics of sound from the reflective surfaces to the user, wherein the second left HRTF and second right HRTF are different from the first left HRTF and first right HRTF; and \n generate a sound signal corresponding to the virtual sound source.
