Creative Instructions (/) The present invention is a short-term evoked otoacoustic transmission signal, especially a high-resolution ear hearing price measurement method. At present, according to a research report, due to the weak sound signal of a person, 'high sensitivity can be used in the external ear: =: ΓΓ number), and the otoacoustic transmission sum can be judged == possible: by analyzing ear sounds _- its The principle is that due to the special structure of the cochlea, the hair cells in place are selective to the frequency of stimulation. The sound axis is stimulated, and the history of a sound: the stimulation frequency of twelve is getting lower and lower. The cochlea responds that the main hair cells transmitting W in the ear 2 are outer hair cells, which change length due to the crossover of the outer hair, so it has the effect of strengthening vibration when the sound waves are transmitted into the cochlea. Furthermore, the artistic quality of hearing and understanding is increased, that is, outer hair cells and hearing are highly correlated. Therefore, the ear sound transmission signal, which can reflect the status of outer hair cells, is highly correlated with normal hearing. After transiently evoking otoacoustic transmission signals (transientiy 〇 and oae), iT 'gives the human ear a short sound stimulus, and the feedback ## in the external auditory canal is Mike Ba 1. The measurement waveform is shown in the third figure. . By measuring and analyzing the otoacoustic transmission signals, we can judge whether the sound waves are transmitted from the ear canal to the ears to stimulate the outer hair cells and whether the function of the outer hair cells is normal. 492264
五、創作說明（/) 而上述方式雖可判斷該耳蜗動作是否正常，但因反射 信號距離耳堝之位置較遠，又加上人體、環境噪音等因 素，而使此一反射信號中挾雜許多雜訊，所以麥克風接收 回來的45虎係包含二種主要成分，一為真正的耳聲傳射信 號，二為環境和人體的噪音，三為刺激信號打到耳道和鼓 膜等所反射回來的信號；故該耳聲傳射信號之信號/雜訊比 將會相對地降低，即檢測聽力之準確性亦相對降低。 然而，在目前市面上之掏取系統中，為了分離出真正 之耳聲傳射信號所使用之方法如下所述·· 因該短暫誘發耳聲傳射信號的信號強度和刺激強度成 非線性關係，且有隨刺激強度增強而漸趨飽和 (saturation，即刺激強度大幅增強但耳聲傳射信號的強 度只非常小幅增加）的趨勢。若於外耳發出—組刺激訊號 Η、+1、+1、-31 ( I為刺激強度）至内耳中，由耳内反射 出一組回傳信:虎（R1、R2、R3、R4)，其中各回傳信號Rl 巴g真正的耳聲傳射^號E丨和刺激信號打到耳道和鼓膜等 所反射回來的信號Ll (Ri=Ei+u，ι = Η)，而耳聲傳射信 唬Ει又可以分解為和刺激強度呈線性關係的部分 (EU)，和非線性關係的部分（ENU)，故將各反射信號 R卜R4相加後，因為耳道、鼓膜等的反射信號^和刺激強 度成線性關係’前三個刺激打到耳道、鼓膜等的反射信號 (LI L2 L3 )的和會跟第四個刺激打到耳道、鼓膜等的 反射信號（L4)，強度相同但正負机反（因為L1:L2=L3二-L4 3)故使4耳道及鼓膜等反射信號會被抵消，又，V. Creation instructions (/) Although the above method can determine whether the cochlea is normal, but the reflected signal is far away from the ear pot, and the factors such as human body and environmental noise make the reflected signal mixed. There is a lot of noise, so the 45 Tiger series received by the microphone contains two main components, one is the true otoacoustic transmission signal, the other is the environment and human noise, and the third is the stimulus signal hitting the ear canal and the eardrum. The signal / noise ratio of the otoacoustic transmission signal will be relatively reduced, that is, the accuracy of detecting hearing is also relatively reduced. However, in the current extraction systems on the market, the method used to isolate the true otoacoustic transmission signal is as follows. Because the signal intensity and the stimulus intensity of the transiently induced otoacoustic transmission signal have a non-linear relationship. And there is a tendency to become saturated with the enhancement of the stimulation intensity (saturation, that is, the intensity of the stimulation is greatly increased but the intensity of the otoacoustic transmission signal is only increased very slightly). If it is sent from the outer ear — a group of stimulation signals Η, +1, +1, -31 (I is the intensity of the stimulus) into the inner ear, a set of postback messages is reflected from the ear: tiger (R1, R2, R3, R4), Each of the returned signals Rl and g is the true otoacoustic emission ^^ E 丨 and the stimulus signal hits the reflected signal Ll (Ri = Ei + u, ι = Η), and the otoacoustic transmission The radio signal can be decomposed into a linear relationship (EU) and a non-linear relationship (ENU) with the stimulus intensity. Therefore, after the reflection signals R and R4 are added, the reflection of the ear canal, eardrum, etc. The signal ^ is linearly related to the intensity of the stimulus. 'The sum of the reflection signals (LI L2 L3) of the first three stimuli hitting the ear canal, eardrum, etc. will be the same as the reflection signals (L4) of the fourth stimulus hitting the ear canal, eardrum, etc. The intensity is the same but the positive and negative machines are reversed (because L1: L2 = L3 二 -L4 3), so that the reflection signals of the 4 ear canals and eardrum will be canceled.

Creation instructions (multiple) The part of the radio signal that has a linear relationship with the stimulus intensity (E⑴ is also divided, leaving only a part of the non-linear relationship with a linear part with a saturated characteristic U ^ Not blessed; it can be seen that, This makes the observation 2 vision 'χ & add four backhauls obtained from a group of four stimuli, and the result is equal to 2 × hunger X cis or 2 × fox 3, that is, ear sound; = part of the stimulus intensity has a non-linear relationship Twice the value, and then get == 2 to get a real short-term evoked otoacoustic transmission signal, a strong yield of 1 (hereinafter referred to as a single group average), but because of this news =, long sundial continuously sends more _ The signal / noise ratio can only be increased by the average value of the single-group average (referred to as the signal averaging method). However, the single-group average obtained based on the methods used in the market extraction system Its signal / noise is relatively low, so there is still room for improvement in the method of capturing otoacoustic transmission signals. To this end, the main purpose of the present invention is to provide a signal / noise ratio that increases the average of a single group, in the hope of short-term Short time to capture higher signal / noise ratio The method of transmitting signals through the ear. The main technical means used to achieve the above purpose is to implement the steps of the method as follows: Send a set of stimulus signals, that is, input a plurality of sound stimulation signals to the inner ear from the outer ear The cochlear part of the cochlea; after the stimulus signal is sent to the ear, a group of the return signals in the ear is sequentially reflected in the ear; the average part of the individual signals in the group of return signals is Send a fixed time point after the individual stimulus as the C7 D7 to distinguish the individual return signals captured. V. Creation instructions (multiple). For the front and back sections, divide the whole group by the -parameter, and get the number ^^ before the number. That is, the average part of the previous section of this method is the average part of the back part of the method. The last part of the back part number of the group is divided by the last return. Identify, ^ ,,, and return "divide by-parameter after addition;" It: the back part of the individual return signal, part after part; the “bluff” is the method after the single group average of the method: the noise ratio is briefly induced by the otoacoustic transmission signal surface D of the otoacoustic transmission signal 'in -Equivalent before a fixed point in time; ::: The reason for the study: the discovery of the Shidao analysis' the intensity of the ear canal and eardrum reflection signals will approach zero in a fixed period of time, so this method only takes-group back pass The first three return signals in the middle are added up and averaged, so the next section of k 5 tiger will be the most complete transient evoked otoacoustic transmission signal (linear + non-linear), so this method can effectively improve The intensity of the otoacoustic transmission signal is briefly induced to increase the accuracy of hearing detection.
