Abstract
A system includes at least one earpiece, wherein each earpiece comprises an earpiece housing, an optical source operatively connected to the earpiece housing, wherein the optical source is configured to emit light toward an ear surface, an optical sensor operatively connected to the earpiece housing, wherein the optical sensor is configured to receive reflected light from the ear surface, and at least one processor disposed within at least one earpiece and operatively connected to the optical source and the optical sensor, wherein the at least one processor is configured to separate the pulse oximetry signals from the audio signals in the reflected light detected by the optical sensor.

A system comprising:
- at least one earpiece, wherein each earpiece comprises an earpiece housing;
- an optical source operatively connected to the earpiece housing, wherein the optical source is configured to emit light toward an ear surface;
- an optical sensor operatively connected to the earpiece housing, wherein the optical sensor is configured to receive reflected light from the ear surface;
- and
- at least one processor disposed within at least one earpiece and operatively connected to the optical source and the optical sensor, wherein the at least one processor is configured to separate the pulse oximetry signals from the audio signals in the reflected light detected by the optical sensor.
A method comprising:
- emitting, via an optical source of a wireless earpiece, light toward an ear surface;
- receiving, via an optical sensor of the wireless earpiece, a reflected light signal from the ear surface;
- separating, via at least one processor of the wireless earpiece, audio signals from pulse oximetry signals within the reflected light signal;
- and
- determining, via the at least one processor of the wireless earpiece, an oxygen saturation level from the reflected light.
The method of claim l lwherein the ear surface comprises an inner ear surface.
