1. An apparatus, comprising:
a processor;
a memory operably coupled to the processor;
at least one light-emitting diode operably coupled to the processor;
a photodetector operably coupled to the processor; and
a plurality of sensors operably coupled to the processor,
the at least one light-emitting diode configured, during operation, to emit light in a direction toward the photodetector and a portion of the emitted light passing through a portion of an ear of a wearer of the apparatus prior to arriving at the photodetector,
the photodetector configured to detect the portion of the emitted light,
the memory storing instructions to cause the processor to:
calculate a biometric parameter of the wearer based on the detected portion of the emitted light;
emit an audible alarm in response to detecting that the biometric parameter has crossed a defined threshold value;
increase a frequency of the audible alarm over time until the wearer interacts with one of an alert actuator of the apparatus or a graphical user interface (GUI); and at least one of:
increase a volume of the audible alarm over time in response to detecting an increase in a calculated difference between the biometric parameter and the defined threshold value,
increase the frequency of the audible alarm over time in response to detecting the increase in the calculated difference between the biometric parameter and the defined threshold value,
decrease the volume of the audible alarm over time in response to detecting a decrease in the calculated difference between the biometric parameter and the defined threshold value,
decrease the frequency of the audible alarm over time in response to detecting the decrease in the calculated difference between the biometric parameter and the defined threshold value, or
increase the volume of the audible alarm over time until the wearer interacts with one of the alert actuator of the apparatus or the GUI; and
store, in the memory, a representation of the biometric parameter and at least one measurement collected by the plurality of sensors.
