Intervention group: After baseline assessments, the child enters the rehabilitation treatment phase. To perform rehabilitation exercises in the presence of noise, one of the ten lists without noise is first presented to the children so that they become familiar with the style of words and how to respond. Then the main exercise begins. The simplest mode of practice is when the signal-to-noise ratio is the ratio of speech to noise consisting of eight speakers. In practice, the speech intensity is fixed at 62dBHL and the initial noise level is 50dBHL, ie SNR = + 12. It should be noted that the best way to do the noise exercise is to align the ear, but if the first step is difficult for the child, the noise can be sent to the other ear and after the child progresses, the noise will be presented in the same ear. At each stage, the child's mistakes must be recorded. Errors include mispronouncing a word, omitting one of the letters, or not saying the whole word. If the child makes less than four to six errors out of ten words in the eight lists, the signal-to-noise ratio is reduced to 2 dB. Exercises are repeated every day for 45 minutes (average about 8 lists) twice a week. Completion of the exercise is the stage when the child can reach the final stage, which is the SNR 0 dB. Or it is better to say that if the child has a total of four to six errors in this ratio and ratios close to zero (such as 2 and 4 decibels), it indicates the child's proper performance in these exercises. If an error occurs and there are more than four errors in each list, it is necessary to repeat other lists at the same SNR level or improve this ratio. So below is the answer to the question, "What should we do if they mispronounce the correct word?" Hold the exercise and tell the child to be careful, listen again, what word do you hear? And we say one of the letters to the child. For example, if the first letter was "n" and not "m", we keep practicing and improve the signal-to-noise ratio.. Yes - There is a plan to make this available What will be shared: The data and documents of this study will be published via thesis and a journal paper When: Access date: form 2022 To whom: Researchers Conditions: Meta-analysis Where to obtain: Contact the project manager How to obtain: Corresponding via email Comments:
