Hearing detection device and detection method based on time-frequency modulation perception threshold

Abstract

The invention belongs to the technical field of auditory test and detection, and particularly relates to a hearing detection device based on auditory cortex time-frequency modulation evoked potential, which comprises a tester terminal used for sending a sound source emission instruction to a sound source output device; a sound source output device is used for transmitting a stimulation sound signal with time frequency modulation to a subject according to the sound source transmitting instruction; a guide electrode is used for recording an electroencephalogram signal obtained after the stimulus sound signal with time frequency modulation is subjected to evoked auditory cortex potential and auditory neuron response processing; a reference electrode is used for recording and providing a reference electroencephalogram signal for the electroencephalogram signal recorded by the guide electrode; a data processing terminal is used for processing the received electroencephalogram signals and the reference electroencephalogram signals, then carrying out speech time domain and frequency domain modulation processing on the electroencephalogram signals and the reference electroencephalogram signals, separating to obtain multiple groups of processing signals consisting of time modulation rates and frequency modulation densities, drawing a test waveform curve, According to the test waveform curve, obtaining a test result; The hearing condition of a subject is detected.

Description

Technical field [0001] The present invention belongs to the field of auditory testing and detection, and in particular, to a hearing detecting device and a detection method based on time frequency adjustment threshold. Background [0002] At present, there are many methods for the treatment of patients with ear disease, but comprehensive hearing detection is performed before diagnosis. The pure tone audition is a most popular, effective inspection method in clinical applications, in clinical applications. It is an inspection technique for inspection techniques for auditory system functionality by observing, recording and analyzing the response to controlled acoustic stimulus. The doctor can not only diagnose the nature of deafness, the degree of hearing obstacles, the quality of the residual hearing, but more importantly, it can obtain a single ear hearing loss, providing parameters for the wearing aid, thus correcting different selection according to the actual situation.

Although such a detection process is simple, long-term work will also cause the detection personnel to feel boring, and repeated detection will often occupy a lot of energy and time of the detection personnel, which greatly reduces the work efficiency of the detection personnel. In addition, due to sometimes In the case of manual interference with the detection results, the subjective detection results cannot be obtained
