Abstract
Systems and methods of calibrating listening devices are disclosed herein. In one embodiment, a method of calibrating a listening device (e.g., a headset) includes determining head related transfer functions (HRTF) corresponding to different parts of the user's anatomy. The resulting HRTFs are combined to form a composite HRTF.
Claims20
A method of calibrating a listening device configured to be worn on a head of a user, the method comprising:
- automatically determining a first head related transfer function (HRTF) of a first part of the user's anatomy using the listening device while the listening device is worn on the user's head;
- automatically determining a second HRTF of a second part of the user's anatomy, wherein the second part of the user's anatomy differs from the first part of the user's anatomy;
- automatically combining portions of the first and second HRTFs to generate a composite HRTF of the user,
- wherein the composite HRTF is personalized to the first and second parts of the user's anatomy;
- and,
- automatically calibrating the listening device for the user based on the composite HRTF.
A method of determining a head related transfer function (HRTF) of a user, the method comprising:
- receiving ambient sound energy from the user's environment at one or more transducers attached to a listening device configured to be worn by the user,
- wherein the one or more transducers are configured to convert the sound energy to electrical audio signals;
- and
- determining the user's HRTF using a processor coupled to the one or more transducers,
- wherein the determining is performed by the processor using the electrical audio signals in the absence of an input signal corresponding to the sound energy received at the one or more transducers.
A listening device configured to be worn on a head of a user, the listening device comprising:
- a pair of earphones coupled via a headband, wherein each of the earphones defines a cavity having an inner surface, and wherein a plurality of transducers disposed proximate the inner surface;
- at least one sensor configured to produce movement signals indicative of movement of the user's head;
- and
- a communication component coupled to the pair of earphones and to the sensor and configured to transmit and receive data,
- wherein the communication component is configured to communicatively couple the earphones and the sensor to a computing device, and
- wherein the computing device configured to compute at least a portion of the user's head related transfer function (HRTF) based at least in part on the movement signals from the sensor.
