Research on auditory neurofeedback technology and its multi-disciplinary applications
AI Summary
Auditory neurofeedback maps brain activity to sound in real time, enabling millisecond-level responses and non-visual regulation, reducing visual fatigue and enhancing ecological validity.
Signal processing workflows support three paradigms: threshold regulation, parameter modulation, and state-dependent triggering, forming the experimental backbone of ANF studies.
ANF applies to neurorehabilitation, psychiatry, sports medicine and auditory screening; challenges include mechanistic evidence and parameter standardisation, with portable ear-EEG and multimodal fusion anticipated.

ABSTRACT
Auditory neurofeedback (ANF) utilizes sound to map brain activity in real-time, guiding individuals to self-regulate neural states via operant conditioning. Compared to visual neurofeedback, ANF offers distinct advantages in millisecond-level response speed and non-visual dependency, significantly enhancing ecological validity and reducing visual fatigue. This paper reviews the physiological basis, signal processing workflows, and three typical experimental paradigms of ANF: threshold regulation, parameter modulation, and state-dependent triggering. Furthermore, it discusses current applications in neurorehabilitation, psychiatric treatment, sports medicine, and auditory cognitive screening. Finally, the paper analyzes challenges regarding mechanistic evidence and parameter standardization, and prospects future trends such as ear electroencephalography-based portable design and multimodal fusion, providing theoretical insights for clinical translation.
