    Abstract: An ear worn device includes an optical source, an optical detector, and a housing supporting the optical source and optical detector. The housing is configured to be positioned within an ear of a subject and includes a first light guide in optical communication with the optical source and a second light guide in optical communication with the optical detector. A distal end of the first light guide is configured to deliver light from the optical source into the ear, and a distal end of the second light guide is configured to collect light from the ear and deliver collected light to the optical detector. The first and second light guides define respective first and second axial directions that are outwardly diverging such that light rays directed into the ear via the first light guide cannot overlap with light rays collected by the second light guide.

    Abstract: A hearing aid includes a speaker driver, an optical source secured directly to the speaker driver, an optical detector secured directly to the speaker driver, a first light guide extending outwardly from the optical source and in optical communication with the optical source, and a second light guide extending outwardly from the optical detector and in optical communication with the optical detector. The first light guide is configured to deliver light from the optical source into an ear region of the subject via a distal end thereof, and the second light guide is configured to collect light from the ear region via a distal end thereof and deliver collected light to the optical detector. The hearing aid may include at least one signal processor configured to process signals produced by the optical detector, and at least one of the following: an accelerometer, a humidity sensor, an altimeter, a temperature sensor.

    Abstract: A method of determining a ventilatory threshold for a subject engaged in an activity includes sensing heart rate information, breathing rate information, and motion information from the subject via a monitoring device worn by the subject; analyzing the heart rate information to identify one or more points in time where heart rate increased at a steady subject workload; and identifying the ventilatory threshold for the subject as occurring at a point in time where an increase in breathing rate lagged an increase in heart rate. The method also includes modifying when the ventilatory threshold for the subject occurs in time by presenting to the subject musical audio having a tempo correlated to frequency characteristics of a heart rate and/or breathing rate of the subject.
