System and method to capture image of pinna and characterize human auditory anatomy using image of pinna

One or more non-transitory machine-readable media comprising computer instructions stored in memory and executable by a processor, the computer instructions to:

• capture an image of a reference pinna;
• based on the image of the reference pinna, determine a non-linear transfer function which characterizes how sound is transformed at the reference pinna, wherein determining the non-linear transfer function comprises inputting the image into a neural network model which outputs the non-linear transfer function;
• and
• output, by a transducer, a signal indicative of one or more audio cues to facilitate spatial localization of sound via the reference pinna, wherein the one or more audio cues is based on the non-linear transfer function.

A system comprising:

• a mobile device having a camera;
• computer instructions stored in memory and executable by a processor to perform the functions of:
• capturing, by the camera of the mobile device, an image of a reference pinna;
• based on the image of the reference pinna, determining a non-linear transfer function which characterizes how sound is transformed at the reference pinna, wherein determining the non-linear transfer function comprises inputting the image into a neural network model which outputs the non-linear transfer function;
• and
• outputting a signal indicative of one or more audio cues to facilitate spatial localization of sound via the reference pinna, wherein the one or more audio cues is based on the non-linear transfer function.
