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.
