In this paper, we introduce our smart phone application for hearing impaired people. Unlike previous hearing aids application, our application has both functions of self hearing tests and sound amplification. We provide user with two types of self hearing test, those are standard hearing test and detail hearing test. Each test has different advantages like short test time and accurate test result, however both tests provide reliable result. Our hearing test allows that user can measure their hearing loss level according to the frequency. Sound amplification function provide proper fitting formula by using NAL-NL1, and it guarantees high speech intelligibility. Our application can also memorize user's fitting data at specific test condition. Therefore those who using our hearing aids application can easily reset their hearing aids / earphone properties periodically. Our application is advanced at the aspect of self fitting function that no other previous application did. So we are expecting these comfortable processes about fitting lead the number of hearing aids user to be increased.

In this study, we developed a wireless CROS(contralateral routing of signal) hearing aid for unilateral impaired people. CROS hearing aid takes sound from an ear with poorer hearing and transmit to another ear with better hearing. Generally, the self-voice delivered through the receiver of CROS hearing aid can be very loud. It is hard to perceive target speech because of loud self-voice. To compensate it, a self-voice suppression algorithm has been developed. we performed SDT(speech discrimination test) for evaluation of the self-voice suppression algorithm. One-syllable words was used as test speech and recorded with self-voice at a 1m distance. As the results, SDT score was improved about 11% when the self-voice suppression algorithm was processed. It is verified that the self-voice suppression algorithm helps speech perception at a time to communicate with others.

The purpose of this study was to identify levels of hearing handicap, depression, and self-efficacy, and to determine the effect of hearing handicap on depression and self-efficacy in home-based elderly. Data were collected from August to September 2017. Two hundred and seventy eight elderly living at home in three cities participated in this study. Data were analyzed using the independent t-test, one-way ANOVA, Scheffe's test, Pearson's correlation coefficients, and by multiple regression analysis using SPSS Ver. 20.0 for Windows. Mean levels of hearing handicap, depression, and self-efficacy were 10.91 (${\pm}19.83$), 4.75 (${\pm}3.90$), and 46.87 (${\pm}6.75$) respectively. A statistically significant positive correlation was observed between hearing handicap and depression (r=.228, p<.001), and significant negative correlations were found between hearing handicap and self-efficacy (r=-.284, p<.001) and between depression and self-efficacy (r=-.526, p<.001). Hearing handicap had a negative effect on self-efficacy (${\beta}=-.161$, p=.008) and its explanatory power was 27.2%. The study results suggest that the developments of multidisciplinary interventions and education programs are important to prevent or minimize hearing handicap in the elderly.

Background: In this research, we conducted an analysis to grasp the relationship between hearing and quality of life and to prepare effective troubleshooting. Methods: In this study, we analyzed using the data of the 6th term of the National Health and Nutrition Survey of the Disease Management Headquarters. And, out of 7,380 people, 3,598 adults over the age of 40 years who participated in the hearing test were selected as final research subjects and analyzed. Results: It was confirmed that the result of the analysis affects the quality of life based on hearing. The quality of life associated with hearing loss was unpleasant, motor ability, anxiety/depression, and everyday life affected in order of self management. And factors having an effect on the quality of life of the study subjects were found to be gender, elderly, unmarried, low hearing, low household income, absence of economic activity, and low teaching standards. Conclusion: The conclusion is that strengthening education for realistic management and prevention rather than treatment for unconditional hearing impairment will overcome low self esteem and loneliness and alleviate any uncomfortable life that people with hearing loss give. It is expected to be possible.

Purpose: The purpose of this study was to investigate the effects of an education program on health promotion behavior for students with hearing impairments. Method: For this study a nonequivalent control group pretest-posttest design was used. The three components of the study were: 1) the recognition of the importance of health promotion behavior, 2) formation of supportive networks, and 3) practice of health promotion behavior. The study population consisted of 38 students with hearing impairments (experimental group [19], control group [19]). The program was provided to students in the experimental group for 50-120 minutes, once a week for 3 weeks. Descriptive statistics, $X^2$-test, t-test, Fisher's exact test, and ANCOVA were used to analyze the data. Results: Perceived social support and health promotion behavior, but not self efficacy, were significantly different between the two groups. Conclusion: The result of this study indicate that this education program for health promotion behavior was effective for promoting perceived social support and health promotion behavior in students with hearing impairments, but further continuous research is needed to identify effective interventions to promote health behavior in students with hearing impairments and to allow for generalization of the results of this study.

This study as a cross survey study was conducted to provide basic data for more practical approach to nursing the aged, by analyzing the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. This study was based on the survey data from the 90 aged, who are over sity years old and resident in Seoul. In order to measure the general characteristics and subjective audition, Cantril's Ladder Scale Tool was used. For the loneliness, UCLA Loneliness Scale Tool (translated into Korean to suit the Korean environment by Kim's). In order to measure the self-esteem, Rosenberg's Self-esteem Measurement Tool (translated into Korean by Chun) was used. No's Quality of Life Measurement Tool was used to the measure the quality of life. The Data were collected by direct interviewing on the subjects for this study from August 10, 1999 to September 15, 1999. In accordance with each purpose of this study, appropriate analyzing methods such as Descriptive Statistics, T-test, and ANOVA were used in analyzing the collected data. Pearson correlation coefficient was used to test the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. The result of this study is as follows: 1) The average of the degrees of subjective audition was 7.22, The factors that cause the result were sex, religion, the perception of health, the married state. 2) The average of the degrees of loneliness was 55.18, The factor that cause the result was the perception of health. 3) The average of the degrees of self-esteem was 28.42, The factors that cause the result were the number of family, the number of children, the perception of health. 4) The average of the degrees of quality of life was 71.87 the factors that cause the result were age, education, the number of children, the perception of health. 5) Correlation of Loneliness, self-esteem and quality of life is the perception of loneliness showed significant negative correlation with self-esteem (r=-.466, p=.0001) and quality of life (r=-.450, p=.0001). As a result of analysis above: Because of the recognition change of the aged, it seems to them that the subjective audition scale on the hearing disturbance aged is measured by only 10-point ladder scale is inappropriate. Therefore, it is necessary that the physiologic-index can confirm more exactly should be applied to them. It is very important that the social-psychological factor that has influence on the aged should be the self-perception of health. Thus, proper development of nursing intervention should be required to process in the self-perception of health on the aged.

Personal hearing devices, such as hearing aids, may be fine-tuned by allowing the users to conduct self-adjustment. Two self-adjustment procedures were developed to collect the listener preferred gains in six octave-frequency bands from 0.25 kHz to 8 kHz. These procedures were designed to allow rapid exploration of a multi-dimensional parameter space using a simple, one-dimensional user control interface (i.e., a programmable knob). The two procedures differ in whether the user interface controls the gains in all frequency bands simultaneously (Procedure A) or only the gain in one frequency band (Procedure B) on a given trial. Monte-Carlo simulations suggested that for both procedures the gain preference identified by simulated listeners rapidly converged to the ground-truth preferred gain profile over the first 20 trials. Initial behavioral evaluations of the self-adjustment procedures, in terms of test-retest reliability, were conducted using 20 young, normal-hearing listeners. Each estimate of the preferred gain profile took less than 20 minutes. The deviation between two separate estimates of the preferred gain profile, conducted at least a week apart, was about 10 dB ~ 15 dB.

Since humans live while feeling rich in their five senses, care must be taken not to damage their hearing in order to lead a happy life. Hearing damage suffered in a living environment is common in a partial band where a specific frequency band is first damaged. However, since the initial pain of hearing damage does not appear much, it is difficult to determine the symptoms in the early stages. In this paper, we proposed a high-speed measurement method that can easily and quickly self-measure hearing damage through a simple app. In this method, 9 pure tones compensated for gain for each voice soub-band are alternately heard in both ears, so that one's own hearing damage can be detected at high speed. When 18 tone pulses were heard for 30 seconds per person, 1 out of 12 subjects was identified as suspected of partial hearing damage. And when the test subjects were informed of the hearing determination method for the number of hearings, the participants themselves immediately determined whether their hearing was damaged. This measurement method simply judges the hearing of both ears within 30 seconds with a smart phone, so that hearing measurements that took more than 10 minutes in hospitals are relatively accurate, and it was found that hearing health can be maintained while reducing time and costs.

This study was conducted to investigate the effect of group music therapy using the traditional drum on the; social adjustment, self-image, and emotional adjustment, of children with hearing impairment. I participated in this group music therapy using the traditional drum with 7 children with hearing impairment for 3 days a week for 6 weeks(including holidays), and each session was 50 minutes long. The evaluation form of this study is a social-emotional development measurement sheet of Meadow-Kendall, which the children's teacher distributed to the children both pre- and post-examination. With these results, the researcher carried out Window SPSS 19 Version and searched for the experiment's effect of measurement cause (I am not sure what this means.) through paired t-test to identify the experiment's effects (social adjustment, self-image, emotional adjustment) as a result of group music therapy using the traditional drum for children with hearing impairment. This study arrived at the following conclusions. First, after I participated in the group music therapy using the traditional drum, the result of the comparisons of the pre-to-post average for social adjustment showed the statistical significance level of the 0.01 standard. Therefore, it was found that the group music therapy using the traditional drum had a positive effect on the social adjustment of children with hearing Impairment. Second, after I participated in the group music therapy using the traditional drum, the result of the comparisons of the pre-to-post average for self-image development showed the statistical significance level of the 0.01 standard. Therefore, the group music therapy using the traditional drum had a positive effect on the self-image of children with hearing impairment. Third, after I participated in the group music therapy using the traditional drum, the result of the comparisons of the pre-to-post average for emotional adjustment showed the statistical significance level of the 0.01 standard. Therefore, the group music therapy using the traditional drum had a positive effect on the emotional adjustment of children with hearing impairment.
