Description

Auditory burden assessment system and method in the case of interference

The invention relates to a system for measuring auditory burden, in particular to an auditory burden assessment system and an evaluation method thereof in the case of interference.

The concept of auditory burden is based on limited resource capacity theory. This theory believes that the brain has limited cognitive resources for processing perceptual information. Therefore, when the peripheral input perceptual signals are disturbed, more resources will be required to process The bottom-up peripheral signals are relatively speaking, the central cognitive process resources that can be invested in top-down are reduced, resulting in an increase in the overall burden. Taking the hearing process in different hearing situations as an example, the burden of noise situations will be higher than that in quiet situations. When the listener wants to maintain the same speech recognition test performance in a quiet situation as the quiet situation, because the surrounding input signal is disturbed by noise, the listener must invest additional cognitive resources to process the received auditory signal, an extra burden The remaining resources that can be allocated to other cognitive processes are reduced, resulting in an increase in the burden on the listener even if he can maintain the performance of speech recognition, and the cognitive performance outside speech recognition will decrease.

When human beings listen and understand speech, they need the operational response of brain activity. When the listening conditions are simple, the resulting auditory burden is small; on the other hand, if the listening conditions are poor or the brain activity is too much interference, the auditory burden will be larger. Hearing burden is affected by many factors: age, environmental noise, and even illness can all increase the hearing burden when listening to speech.

The hearing test of the conventional technology mainly uses an audiometer to play a sound effect to detect whether the subject can respond correctly or to measure the physiological response of the subject to a stimulus sound by using an electrophysiological measurement method. However, none of the above-mentioned conventional testing methods takes into account changes in the hearing burden of the subject, so the accuracy of the test results is quite limited.

Therefore, the applicant of this case hopes that a system that can measure the hearing burden of the subject can be added to the existing hearing test, so as to provide further test information to accurately understand the performance of the hearing ability of the subject.

Therefore, this case hopes to propose a new auditory burden assessment system and its assessment method in the case of interference, so as to solve the above-mentioned shortcomings in the prior art.

(I.e. display test), control the performance of the subject on the main test, and observe the decline in the subject's performance on the secondary test to measure the change in auditory burden.

When using dual tests to measure the auditory burden, since the auditory burden is the cognitive resources 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 to the degree of decline in measurement performance The auditory burden can therefore consist of many different forms.

As shown in FIG. The difference between the sound decibel value and the actual measured environment, so that the set value of the system is consistent with the actual environment (step 900).

The voice test apparatus 10 performs a voice test on the subject (step 901). The voice test device 10 plays different words and phrases, so that the subject responds according to hearing (such as verbally reciting the voice heard or pressing a control button) to determine the subject Whether the tester can clearly hear the test words (for example, the tester presses a specific control button to record whether the testee recites correctly).

Wherein, in the voice test device 10, for various words and sentences stored in the word library 11, various noises stored in the noise database 12 are added. The required words or sentences are output from the word library 11. Generate the required noise according to the set noise conditions (such as system noise, voice noise, or environmental noise, or various noise combinations and noise levels). The adder 133 adds the selected word and the noise generated by the noise adding unit 132 and outputs the added word.

The speaker 14 receives the output signal of the adder 133 and converts it into a voice signal, so that the subject can listen to the voice signal.

At the same time, the display test device 20 performs a display test on the subject (step 902). The display test device 20 is used to display different display test questions, and the test subject is allowed to make a reply to determine whether the test subject can answer the displayed display test question correctly.

The display test question may be a display of visual stimulus and measure the time for the subject to respond to the items required in the test question bank 21, or a visual pattern tracking, or a visual attention test, or a simple arithmetic test, Or vocabulary memory tests and other application display methods to make users respond to the questions.

Wherein, the test question selecting unit 22 is used to select and display the test questions from the test question bank 21 according to a predetermined logic and a specified classification and level. And via The display screen 23 displays display test questions selected by the test question selecting unit 22.

Among them, different words, noises and different display test questions form different combination test questions.

Test results of the voice test and the display test are determined in the effect evaluation unit 30 (step 903). In the effect evaluation unit 30, the speech test effector 31 receives the words and sentences output from the speech test device 10 and the results of the speech test by the subject, and compares the results of the two to determine the two. Whether they match.

At the same time, in the effect evaluation unit 30, the display test effector 32 receives the results of the display test from the test subject, and connects the test question selection unit 22 to determine whether the test subject's results of the display test are correct. .
