Description

Auditory burden assessment system and its assessment method under interference

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.

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.

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.

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.
