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.
