Description

Late perception test device and late perception test method using the same

The present invention relates to a speech perception test device and a method of perceptual perception using the same, and more particularly, an open-set test for infants having limited communication ability, such as hearing impairment, or developing language. And close-set tests, but by oral or visual enhancement of the closed-set and open-set tests to significantly increase the perceptual test efficiency. It relates to a late perception test device and a late perception test method using the same.

Conversation is the most basic and important element of human communication. Dialogue means the process of listening to words (words or sentences) of another's doctors and sending and receiving words (words or sentences) containing their intentions, of which the sound is transmitted to the brain through the ear. After the brain has a process of recognizing the meaning of words. Therefore, in order for normal conversation to be possible, listening ability, that is, speech perception and speech perception must be normal.

Here, the perception of speech refers to whether the speech is normally transmitted to the brain through the ear, and the perception of speech refers to whether the meaning of the speech is normally recognized in the brain through the perception of speech.

As a result, when speech perception is abnormal, hearing impairment is usually impaired. When speech perception is abnormal, hearing ability is normal or abnormal in the brain, including problems in speech perception due to impairment of hearing ability. This is because most of the treatment is very different according to each.

First, look at the device to check whether the speech perception is normal,

The ear, which consists of the outer ear, middle ear, and inner ear, hears a wrong sound if any part of them occurs. This phenomenon is called hearing loss, and the general hearing test method for measuring the hearing loss is largely classified into two methods. This is based on six frequency bands: 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, and 8000 Hz. There are three methods, the descending method, the ascending method, which is gradually measured at an inaudible weak level, and the modified method which is a combination of the two methods.

In particular, as disclosed in Korean Patent Publication No. 10-0917714 (Hearing device and its control method), the hearing tester's hearing that is close to real life is found by using sound data for hearing measurement that has been corrected for each hearing for the sound source. On the basis of this, a hearing measurement device was developed to calculate the hearing aid correction value suitable for the subject, and to apply the calculated correction value to a sound source in an environment similar to real life, to make a sound source for verifying hearing measurement results, and to have the same experience as when using a hearing aid before using the hearing aid. have.

However, this hearing measuring device is not suitable for infants in language development due to difficulty in communication with the examiner, and even if it is judged that speech perception is abnormal through the device, this does not represent speech perception ability. As a result, there is a redundancy of tests that require separate speech perception tests.

In addition, look at how to check whether the late perception,

Currently used in Korea, the standardization process is currently in progress and EARS-K (Evaluation of Auditory Response to Speech-Korean) developed from 3 years old or older using various test tools and questionnaires ranging from sound recognition to sentence perception version), a standardized process, and a method of following the instructions given only by listening to the Korean Speech Audiometry, a speech tester ranging from words to sentences, and potato figurines. Potato Head method.

However, this is greatly influenced by test-related factors such as the test subject's performance and test environment, and in particular, subjects with limited communication ability are unable to measure or have low reliability of the results, as well as vocabulary and language development. Infants are more difficult to measure because they are influenced by more factors and show different patterns. In addition, there is a problem in that the result is not objective because the subject performs the evaluation program, which is not configured as an apparatus but is composed of a test tool and a questionnaire.

In particular, children under 3 years of age are not provided with perceptual tests or obtain only information at the closed-set level, resulting in an open-set modified to overcome this limitation. Although tests have been developed, it is not possible to provide information on speech perception at the phoneme level if the child does not speak along.

Therefore, considering the level of speech perception through speaking is an important step directly related to auditory rehabilitation, it is necessary to reflect the frequency and arrangement of Korean phonemes and to develop the speech perception test that matches the developmental process and level of infants as soon as possible. In addition to evaluating the hearing ability of the infant, it is required to develop a device capable of providing objective evaluation data on perception without relying on the examiner's performance.
