Description
本發明係有關於用於測量聽覺負擔的系統,尤其是一種干擾情況下聽覺負擔評估系統及其評估方法。 The present invention relates to a system for measuring auditory burden, especially a system for evaluating auditory burden under interference conditions and an evaluation method thereof.
聽覺負擔的概念是基於容量有限理論(limited resource capacity theory),此理論認為大腦用於處理知覺訊息的認知資源有限,因此當周邊輸入的知覺訊號被干擾時,會需要投入更多的資源處理來自周邊由下而上(bottom-up)的知覺訊號,相對而言,能投入在由上而下(top-down)的中樞認知歷程資源減少,導致整體負擔上升。以不同聽覺情境下的聽覺歷程為例,噪音情境的負擔會較安靜情境下高。當聽者欲在噪音情境下維持和安靜情境相同的言語辨識測驗表現時,由於周邊輸入的訊號受到噪音干擾,聽者必須要投入額外的認知資源對接收到的聽覺訊號進行處理,額外的負擔使剩餘可分配給其他認知歷程的資源減少,導致聽者即使能維持言語辨識的表現,其負擔也會增加,使言語辨識外的其他認知表現下降。 The concept of auditory burden is based on the limited resource capacity theory. This theory believes that the brain has limited cognitive resources for processing perceptual information. Therefore, when the perceptual input signals from the surroundings are disturbed, more resources will need to be invested in processing from Peripheral bottom-up (bottom-up) perception signals, relatively speaking, reduce the resources that can be invested in the top-down (top-down) central cognitive process, leading to an increase in the overall burden. Taking the auditory process in different auditory situations as an example, the burden of noise situations will be higher than that of quiet situations. When the listener wants to maintain the same speech recognition test performance in a noise situation as in a quiet situation, because the surrounding input signals are interfered by the noise, the listener must invest additional cognitive resources to process the received auditory signals, which is an additional burden The remaining resources that can be allocated to other cognitive processes are reduced. Even if the listener can maintain the performance of speech recognition, the burden will increase, and other cognitive performances other than speech recognition will decline.
人類在聆聽與理解語音時,需要大腦活動之運作反應, 當聆聽條件簡單時,所產生的聽覺負擔較小;反之,若聆聽條件不良或是大腦活動干擾過多時,則聽覺負擔會較大。聽覺負擔會受到許多因素影響:年齡、環境噪音甚至是疾病都有可能使聆聽語音時的聽覺負擔增加。 When human beings listen and understand speech, they need the operational response of brain activity. When the listening conditions are simple, the auditory burden will be small; conversely, if the listening conditions are poor or there is too much brain activity interference, the auditory burden will be greater. The auditory burden will be affected by many factors: age, environmental noise and even disease may increase the auditory burden when listening to speech.
習知技術的聽力測試,主要是應用聽力檢查儀撥放音效以檢測受測者是否能正確反應,或是利用電生理測量方式測量受測者對刺激音的生理反應。惟上述習知的測試方式均沒有考量到受測者的聽覺負擔變化,因此其測試結果的準確度相當有限。 The hearing test of the conventional technology mainly uses the hearing tester to play the sound effect to detect whether the subject can respond correctly, or the electrophysiological measurement method is used to measure the physiological response of the subject to the stimulus sound. However, none of the above-mentioned conventional test methods takes into account the changes in the auditory burden of the testee, so the accuracy of the test results is quite limited.
因此本案申請人希望能在現有聽力測試中加入一種可測量受測者聽覺負擔的系統,便能提供更進一步的測試資訊,以準確了解受測者的聽覺能力表現。 Therefore, the applicant in this case hopes to add a system that can measure the auditory burden of the subject to the existing hearing test, so as to provide further test information to accurately understand the auditory performance of the subject.
故本案希望提出一種嶄新的干擾情況下聽覺負擔評估系統及其評估方法,以解決上述先前技術上的缺陷。 Therefore, this case hopes to propose a brand-new auditory burden evaluation system and its evaluation method under interference conditions to solve the above-mentioned shortcomings in the prior art.

請參考圖1至圖4所示,顯示本發明之干擾情況下聽覺負擔評估系統。本案之系統將使用雙測驗的方式測量聽覺負擔,係應用同時進行兩項測驗時短期記憶與注意力資源會互相競爭的原理,要求受測者同時完成主要測驗(即語音測試)與次要測驗(即顯示測試),控制受測者在主要測驗上的表現,並觀察受測者在次要測驗上表現下降的程度,以測量聽覺負擔的變化。 Please refer to FIG. 1 to FIG. 4, which show the auditory burden assessment system under interference conditions of the present invention. The system in this case will use a dual test method to measure the auditory burden. It applies the principle that short-term memory and attention resources will compete with each other when two tests are performed at the same time. The subject is required to complete the primary test (ie speech test) and the secondary test at the same time. (I.e. display test), control the subject’s performance on the main test, and observe the degree of decline in the subject’s performance on the secondary test to measure the change in auditory burden.
以雙測驗測量聽覺負擔時,由於聽覺負擔為完成語音測試所需的認知資源,故以語音測試作為主要測驗;而次要測驗的主要目的為提供受測者額外負擔,依測量表現下降程度反應聽覺負擔,因此可由許多不同形式組成。 When the dual test is used to measure the auditory burden, since the auditory burden is the cognitive resource required to complete the voice test, the voice test is used as the main test; the main purpose of the secondary test is to provide the subject with an additional burden, and respond according to the degree of decline in the measurement performance The auditory burden can therefore be composed of many different forms.
