Problems solved by technology

[0005] However, short sounds and short pure tones, which are the stimulus sound sources for ABR waveform detection, are sound signals of all frequency components contained in them that are sent out at the same time when the sound is emitted, and the traveling wave delay of sound conduction has not been considered, thus resulting in the final superimposed average The obtained ABR signal may have the problem that the signals of various frequency components cancel each other out, resulting in poor ABR signal quality, resulting in a small response range of the induced ABR waveform, and the most accurate ABR waveform cannot be obtained.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of neural engineering, and in particular to a method and device for detecting auditory brainstem evoked potentials. Background technique [0002] For a given sound stimulus, the auditory system will produce a series of potential responses, and the nerve nuclei and their nerve fibers in the auditory conduction pathway will be stimulated and excited to produce small potential changes. By recording the waveform changes of these potentials and using various digital signal processing algorithms to extract them from various strong noise backgrounds, they are auditory brainstem evoked potentials, which are used to evaluate the integrity of the auditory conduction system and monitor the function of the nervous system Important indicators. [0003] The auditory brainstem evoked potential usually detected clinically is 5-7 continuous brain wave peaks induced by sound stimulation, each peak inter...
