Presented herein are systems and methods of providing acoustic stimulation to a human subject in order to evoke an auditory response. The method includes generating a chirp signal, where generating the chirp signal includes adding a plurality of frequency signals, each frequency signal being delayed in the chirp signal based on its associated frequency-specific basilar membrane delay, the frequency-specific basilar delay being determined as a function of an in-vivo frequency-specific basilar membrane delay.

This application relates to the field of language processing technology, specifically to a brain-computer interface-based auditory stimulation enhancement and reconstruction system. The system includes: a signal acquisition module for acquiring background noise and auditory signal data, obtaining the background noise and auditory response spectra; a background noise analysis module for constructing background noise interference intensity based on the differences between various physiological electrical signals and the background noise spectrum; an over-subtraction factor adjustment module for adjusting the over-subtraction factor based on the background noise interference intensity and the overlap between strong interference physiological electrical signals and the auditory response spectrum; a spectral lower limit parameter adjustment module for determining the optimal spectral lower limit parameter by analyzing the noise performance balance under each spectral lower limit parameter after spectral subtraction; an over-subtraction factor correction module for correcting the over-subtraction factor using the optimal spectral lower limit parameter; and a signal reconstruction module for reconstructing the auditory signal sequence obtained through the spectral method. This improves the denoising effect of music noise while simultaneously reducing the influence of other noises on the auditory signal, resulting in better auditory stimulation enhancement.

The invention provides an anesthesia depth monitoring method, system and device based on auditory response and a medium, and the method comprises the following steps: constructing and outputting a composite auditory stimulation sequence formed by alternate circulation of a steady state evoked segment and a cognitive probing segment, the cognitive probing segment being a rapid presentation with a stimulation interval smaller than evoked potential duration; the continuous scalp electroencephalogram of the subject is acquired. Intercepting steady-state evoked section data, extracting steady-state auditory evoked response features and calculating a first anesthesia depth index; intercepting cognitive exploration section data, extracting event-related potential by adopting an overlapped signal separation algorithm, and calculating a second anesthesia depth index. And determining two confidence coefficients weights based on the signal quality of the steady-state section and the residual noise of the cognitive section, carrying out weighted fusion on the two indexes according to the weights, and generating and outputting a comprehensive anesthesia depth index for real-time and robust anesthesia depth evaluation and prompt. By implementing the technical scheme provided by the invention, the problem of low updating rate of traditional cognitive potential monitoring data can be solved.
