Method and system for collecting and processing bioelectrical and audio signals
A method and system for detecting bioelectrical signals and audio signals from a user, including establishing bioelectrical contact between a user and one or more sensors of a biomonitoring neuroheadset; collecting, at the one or more sensors, one or more bioelectrical signal datasets; collecting one or more reference signal datasets; collecting, at a microphone of the biomonitoring neuroheadset, an audio signal dataset; and generating a combined audio and bioelectrical signal processed dataset, including producing a noise-reduced bioelectrical signal dataset, and producing a conditioned audio signal dataset.
1 . A system, comprising:
an earpiece comprising:
an in-ear earbud mounted to an electronics capsule, the in-ear earbud comprising a speaker and an electroencephalogram (EEG) sensor;
a wearable support frame mounted to the electronics capsule, wherein the wearable support frame comprises a primary curvature configured to hook around an ear of a user, wherein the wearable support frame houses a common mode sensor and a driven right leg electrode, wherein the wearable support frame is mounted to the electronics capsule at a first end of the primary curvature, wherein the driven right leg electrode is positioned on the primary curvature between the common mode sensor and the first end, wherein the wearable support frame is configured to bias the common mode sensor and the driven right leg electrode against skin of a mastoid process of a temporal bone of the user and behind a flap of the ear of the user, wherein the common mode sensor is vertically arranged relative to the driven right leg electrode when the wearable support frame is hooked around the ear of the user;
a microphone; and
a processing module comprising a processing subsystem housed in the electronics capsule, the processing module configured to:
determine a driven right leg signal to apply to the driven right leg electrode based on a reference signal received from the common mode sensor; and
determine a bioparameter for the user based on: an audio signal received from the microphone and an EEG signal received from the EEG sensor.
2 . The system of claim 1 , wherein the microphone is housed in the electronics capsule.
3 . The system of claim 1 , wherein the processing module is configured to perform an audio signal analysis using a speech recognition model, wherein the bioparameter is determined based on the audio signal analysis.
4 . The system of claim 1 , wherein the processing module receives the EEG signal contemporaneously with receiving the audio signal.
5 . The system of claim 1 , wherein the processing module is configured to transmit an audio sample to the speaker simultaneously with receiving the audio signal from the microphone.
6 . The system of claim 1 , further comprising a second earpiece comprising:
a second in-ear earbud mounted to a second electronics capsule, the second in-ear earbud comprising a second speaker and a second EEG sensor; and
a second wearable support frame mounted to the second electronics capsule, wherein the second wearable support frame houses a second common mode sensor and a second driven right leg electrode;
wherein the processing module is configured to further determine the bioparameter based on a second EEG signal received from the second EEG sensor.
7 . The system of claim 6 , wherein the processing module is further configured to generate a virtual reference signal from the reference signal and a second reference signal received from the second common mode sensor, wherein the virtual reference signal corresponds to a virtual reference location between the reference signal and the second reference signal in signal space, wherein the driven right leg signal is determined based on the virtual reference signal.
8 . The system of claim 7 , wherein the EEG signal and the second EEG signal are each referenced to the virtual reference signal.
9 . The system of claim 6 , wherein the processing module further comprises a second processing subsystem housed in the second electronics capsule.
