摘要：
A system for describing the operation of the brainstem of a person (4), configured to detect the response to the sounds of the person (4), comprising an apparatus for stimuli generation (1) configured to generate sound stimuli, one communication element (2) that connects the person (4) the aforementioned sound stimuli previously by a generator sound device (3), an apparatus for analysis and storage (6) of the electrophysiological brain activity of the person through elements (7) attached to the person (4), characterized in that said sound stimuli having various physical properties of frequency, time and amplitude, and said apparatus for stimuli generation (1) is communicatively coupled to a activation device (5), and said apparatus for stimuli generation (1) is configured to transmit an activation signal, by means of said activation device n (5), to said apparatus for analysis and storage (6) of the electrophysiological brain activity, while these sound stimuli are transmitted to the person (4) from the apparatus for stimuli generation (1) and the system is configured for the auditory brainstem and is configured to measure an auditory brainstem response upon said activation signal to measure the activity of the brainstem within a time span of between 0 and about 10 ms after the beginning of said sound stimuli wherein the system is configured to perform a battery of tests, said test battery comprising nine tests presented to the person, wherein each mentioned test consists of presentation of stimuli to the person (4) and registration of the electrophysiological responses to mentioned stimuli, wherein the system is further configured so that mentioned sound stimuli are presented in repeated sequences wherein said test battery comprising nine subtests: "previous masking" - the reduced ability to perceive one sound in the presence of another sound that precedes it in time followed by "back masking" - the reduced ability to perceive one sound in the presence of another s
