Abstract: Systems and methods are described that may provide audio information about an environment around a wearable device. Such audio information may be correlated with other biometric data to provide physiological information, e.g. regarding a wearer of the wearable device. For example, an illustrative method includes receiving an audio signal via a microphone of a wearable device and rectifying the audio signal with a peak detector. The method further includes amplifying the rectified signal with a logarithmic amplifier and causing an analog to digital converter (ADC) to sample the logarithmic signal. The method also includes causing the ADC to convert the sampled logarithmic signal to a digital output and storing the digital output in a memory of the wearable device. In some embodiments, the method includes transmitting the digital output to a computing device, which may correlate the digital output with other biometric data.

Abstract: Devices are described herein including mounts configured to removably mount electrodes and other elements of the devices to a garment (e.g., a close-fitting undergarment) of a wearer. The devices include at least two electrodes configured such that the electrodes are maintained in secure electrical contact with skin of the wearer when the device is so mounted. The devices can be mounted to garments at various locations on the torso of the wearer such that an electrocardiographic signal related to the electrical activity of the heart of the wearer can be extracted from voltage fluctuations between the at least two electrodes. Such devices can be used for continuous logging or other applications of the electrocardiographic signals of the wearer. Such logged electrocardiographic signals could be used to determine a medical or health state of the wearer.
