Referring to FIG. 1, an embodiment 100 of a pulsatile tinnitus diagnostic system according to the present invention includes an acoustic information acquisition unit 110, an acoustic information storage unit 120, an acoustic information generation unit 130, (140).

The acoustic information obtaining unit 110 is inserted into the external ear canal of the subject to obtain acoustic information of the subject's eccentricity. The acoustic information obtaining unit 110 includes an acoustic interface such as a microphone inserted to seal the ear canal, a sound card capable of transmitting the acoustic signal collected from the microphone to a computer, and a sound recorder. The microphone is similar to a typical earphone, and has a non-directional condenser microphone that operates with external power supply, and a rubber ring type kernal ring that facilitates close contact with the external ear canal. .

The acoustic information storage unit 120 converts the far-sighted sound information obtained by the sound information obtaining unit 110 into digital sound information and stores the converted digital sound information. The acoustic information storage unit 120 amplifies the far-end acoustic information to a sufficient size through a dedicated preamplifier, converts the acoustic information into digital sound information that can be analyzed by a computer via an audio interface, and stores the digital sound information. The digital sound information may be in the form of pulse code modulation (PCM). The acoustic information storage unit 120 may be a hard disk, a semiconductor storage device, a network storage device, or the like for storing digital sound information.

The acquired acoustic information includes a variety of information related to the pseudophakic tinnitus.

Figs. 2 to 5 are diagrams showing echo-acoustic information according to a causative disease that causes pulsatile tinnitus.

FIG. 2 is a graph showing a time-amplitude graph of acoustic information of aberrant carotid artery testee, FIG. 2 (a) is a diagram showing acoustic information of far-sightedness when the examinee turns his head toward the tinnitus side, Fig. 2 (b) is a view showing acoustic information of the out-of-sight when the examinee turns his head toward the opposite side of the tinnitus.

FIG. 3 is a graph showing a time-amplitude graph of acute fibrillation auditory information of an examinee of an arteriovenous fistula. FIG. 3 (a) is a view showing acoustic information of far-sightedness when the examinee turns his or her head toward the tinnitus side, (b) is a diagram showing the acoustic information of the out-of-sight when the examinee has bowed his or her head.

FIG. 4 is a graph showing a time-amplitude graph of acute acoustic information of a subject with a glomus tympanicum. FIG. 4 (a) shows acute acoustic information when the subject turns his or her head toward the tinnitus side , And FIG. 4 (b) is a diagram showing acoustic information of the out-of-sight when the examinee turns his or her head toward the opposite side of the tinnitus.

As shown in FIG. 2 to FIG. 5, it can be seen that the acoustic information on the aberration is different according to the causative disease that causes the tinnitus tinnitus. Also, it can be seen that the acoustic information is different depending on the posture of the examinee. That is, even if the auras due to the same underlying disease are acoustic information, the acoustic information is different even when the subject turns his / her head to the tinnitus side or presses the neck of the tinnitus and the subject turns his / her head with his / her head. Thus, it is possible to know the cause of the subject's tinnitus and the location of the causative disease.

Returning to FIG. 1, the sound information generating unit 130 generates sound information to be inspected based on the digital sound information stored in the sound information storing unit 120. The sound information generating unit 130 may convert the digital sound information into frequency components through an acoustic engineering spectrum analysis to generate sound information to be inspected. The digital acoustic information can be converted into frequency components through Fast Fourier Transform (FFT). Through this analysis, it is possible to analyze objectively the change of the frequency component according to the posture or the change in the strength of each frequency before and after the operation by analyzing the intensity of frequencies abnormally distributed in comparison with the normal person.

The frequency components within the audible frequency band (20 to 20,000 Hz) can be selected through the fast Fourier transform (FFT) of the digital sound information and converted into sound information to be examined. When this is expressed by a spectrogram, it is possible to observe the amount of change of the sound intensity of each frequency component according to the change of time, and thereby, the characteristic of the acoustic information can be objectified.

Referring back to FIG. 1, the sound information analyzer 140 previously stores reference sound information corresponding to the causative disease that causes the tinnitus tinnitus, and the reference sound information and the sound of the sound generated by the sound information generator 130 The information is compared to analyze information related to the subject's tinnitus tinnitus. The sound information analyzer 140 stores reference sound information corresponding to various cause diseases that cause the tinnitus tinnitus in advance. The reference sound information includes various kinds of sound information to be compared with the sound information to be inspected. For example, acoustic information of a normal person, acoustic information corresponding to a causal disease causing a pulsatile tinnitus, acoustic information according to various postural changes, acoustic information according to degree of a causative disease causing a pulsatile tinnitus, And various sound information such as front and rear sound information. In addition, the shape of the acoustic information can be diversified into information on amplitude with time, information on intensity according to frequency, and spectrogram information of time-frequency-intensity, so that the tinnitus tinnitus can be diagnosed more accurately and objectively .

By comparing the previously stored reference sound information with the sound information to be inspected in this way, the sound information analyzing unit 140 can detect the presence or absence of the tinnitus tinnitus of the subject, the cause disease causing the tinnitus tinnitus, the degree of tinnitus tinnitus, The relevant information can be analyzed. The acoustic information analyzing unit 140 can analyze the frequency of the beating tinnitus perceived by the examinee using the sound information to be inspected converted into the frequency component. because of this. It is possible to objectively diagnose whether the tinnitus tinnitus perceived by the subject is high frequency or low frequency. In addition, if the acoustic information analyzing unit 140 obtains the acoustic information of the out-of-sight according to the change of the attitude of the examinee, the acoustic information analyzing unit 140 can diagnose the location of the causative disease causing the tinnitus of the subject.

The acoustic information analyzer 140 acquires and stores reference acoustic information in advance. The reference sound information to be secured includes various types and various types of sound information, as described above.

Next, the out-of-sight acoustic information is acquired from the external auditory canal of the subject (S220). To this end, the acoustic information obtaining unit 110 obtains acoustic information of the subject's eccentricity by inserting a microphone or the like into the external auditory canal of the subject, as described above. At this time, according to the attitude of the subject, acoustic information of the posture can be acquired by posture.

Next, the far-sighted sound information is converted into digital sound information (S230). The acoustic information storage unit 120 may receive out-of-sight acoustic information, amplify the acoustic information, convert it into PCM data, and store the converted data.

Next, the sound information to be inspected is generated based on the digital sound information (S240). The sound information generating unit 130 generates sound information to be inspected to be inspected according to the characteristics of the examinee based on the digital sound information. The acoustic information to be inspected can be generated by converting digital sound information into frequency components, and fast Fourier transform can be used for this purpose. Also, the acoustic information to be inspected can be converted into a frequency component in the audible frequency band (20 to 20,000 Hz).
