Abstract
Techniques for calibrating listening devices are disclosed herein. The techniques include emitting a predetermined audio signal using an outward-facing transducer located on a first portion of a head-mounted device worn by the user, receiving the predetermined audio signal at a microphone located on a second portion of the head-mounted device, the second portion being different from the first portion, determining a transfer function for the user based on the received predetermined audio signal, and applying the transfer function to audio signals transmitted to the user.
Claims13
A method of customizing sound for a user, the method comprising:
- emitting a predetermined audio signal using a transducer located on an outer surface of an earphone of a head-mounted device worn by the user or on a headband of the head-mounted device;
- receiving the predetermined audio signal at a microphone located within an interior of the earphone on a second portion of the head-mounted device;
- determining a transfer function for the user based on the received predetermined audio signal, wherein determining the transfer function comprises determining one or more characteristics of a pinna of an ear of the user;
- and
- applying the transfer function to audio signals transmitted to the user.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform steps to customize sound for a user, the steps comprising:
- emitting a predetermined audio signal using a transducer located on an outer surface of an earphone of a head-mounted device worn by the user or on a headband of the head-mounted device;
- receiving the predetermined audio signal at a microphone located within an interior of the earphone of the head-mounted device;
- determining a transfer function for the user based on the received predetermined audio signal, wherein determining the transfer function comprises determining one or more characteristics of a pinna of an ear of the user;
- and
- applying the transfer function to audio signals transmitted to the user.
A head-mounted device comprising:
- a transducer located on an outer surface of an earphone of the head-mounted device or on a headband of the head-mounted device;
- a microphone located within an interior of the earphone of the head-mounted device;
- wherein the head-mounted device is configured to:
- emit a predetermined audio signal using the transducer;
- receive the predetermined audio signal at the microphone;
- determine a transfer function for a user based on the received predetermined audio signal, wherein to determine the transfer function the head-mounted device is configured to determine one or more characteristics of a pinna of an ear of the user;
- and
- apply the transfer function to audio signals transmitted to the user.
