    Abstract: Techniques and apparatuses are described that perform heart rate variability detection using a hearable. A hearable 102, such as an earbud, is capable of performing a novel physiological monitoring process termed herein audioplethysmography 110, which is an active acoustic method capable of sensing subtle physiologically-related changes observable at a user's outer and middle ear 108. Instead of relying on other auxiliary sensors, such as optical or electrical sensors, audioplethysmography 110 involves transmitting and receiving acoustic signals to monitor a user's biometrics, including heart rate variability 112 and/or blood pressure 114. In addition to being relatively unobtrusive, some hearables 102 can be configured to support audioplethysmography 110 without the need for additional hardware. As such, the size, cost, and power usage of the hearable 102 can help make health monitoring accessible to a larger group of people and improve the user experience with hearables 102.
