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.
