Purpose : Aim of the this study was conducted to determine whether hearing aids are responsible for the quality of life by comparing quality of life between the elderly who are suspected of difficulty in hearing selected by Hearing Handicap Inventory of Elderly (HHIE) without using hearing aids and who are using hearing aids. Methods : For the study, two groups of 33 people were analyzed for independent t-test based on whether they wore Hearing Aids (HA) or not whom wearing hearing aids (hearing aids users) and suspected difficulty in hearing. who are attending the Religious organization Senior Welfare Center in the OO region. Result : The quality of life of hearing aid users is generally observed to be higher than that of non-users in general, and by the section, psychological (p=0.019) and living environment (p=0.032) were appeared statistically signigicant. The elderly showed a significant difference. In the section, "Operation Satisfaction (p=0.038)" in the physical health area, "relationship of reason (p=0.018)" in the social relationship area, "Economic margin (p=0.021)" in the environmental area, "Information accessibility (p=0.020)", In the psychological area, hearing aid was used for "self satisfaction (p=0.033)", "concentration of work (p=0.045)". Conclusion : The use of hearing aids by hearing loss elderly improves the quality of life in the psychological health and living environment section.

Hearing aids play an very important role in aural rehabilitation for hearing impaired person who could not be medically treated. Especially, hearing aids with dynamic range compression (level dependent frequency response: LDFR) method concentrated dynamic output range of receiver into the narrowing dynamic range of sensorineural hearing impaired person. Thus, if aided hearing threshold level is improved and uncomfortable loudness level rises, then the users of hearing aids are favored with extended dynamic range. This study aims to evaluate audiological benefits in dynamic range compression hearing aids. To achieve this, pure tone and speech audiometry were examined to 15 children and 3 adults with narrow dynamic range moderate-to-severe binaural sensorineural hearing loss.

In this research, we tried to implement a PDA (Personal Digital Assistant)-based hearing aids fitting system to manipulate hearing aids-fitting parameters in the user's local environment. Due to the inherent portability of PDA system, we can consequently perform the hearing aids fitting operation without visiting a special site.

본 연구는 청각장애인의 보청기사용에 영향을 미치는 요인을 탐색하기 위해 4차년도 장애인 고용패널 521명을 대상으로 분석하였다. 분석은 Andersen-Newman의 서비스 이용모델을 기반으로 선행요인, 가능성 요인, 욕구요인으로 구분하여 각각의 요인들이 청각장애인의 보청기 사용에 미치는 영향력을 살펴보기 위해 로지스틱 회귀분석(logistic regression)을 실시하였다. 분석결과 선행요인에서는 연령과 교육수준이 높을수록, 가능성 요인에서는 총소득이 낮고 장애수용정도가 높을수록, 욕구요인에서는 장애등급이 낮을수록 보청기 사용수준이 유의미하게 높아지는 것으로 나타났다. 이러한 결과를 토대로 연구의 제한점과 함의를 제안하였다.

청각학적 재활은 청력손실 배경 정보 획득, 청각학적 평가, 보청기 전기음향특성 분석, 음향 이득 결정만으로도 충분히 만족스러운 서비스를 제공할 수 있다. 그러나 청력은 나빠질 수 있고, 보청기는 출력음압이 낮아지거나 고장이 발생할 수도 있다. 따라서 청력손실의 조기 발견과 정기적인 추적 관찰은 매우 중요하다. 이 연구는 정상적인 추적에도 불구하고 보청기 조절 실수가 확인된 증례를 통해 효과적인 청각언어재활 방향을 고민하는데 목적이 있다.

Digital hearing aids enclose $6{\sim}8$ tiny components. Those electromechanical components are individually wired by soldering which is a manual labor and sometimes causes components' damage by heating. This paper suggests a PCB design for overcome these problems. Several PCBs are designed and manufactured and circuited to produce ITE(In The Ear) type hearing aids which are inserted in the ear canal. The most optimal size of the PCB design for the ITE hearing aid is presented in this paper.

본 사례연구는 보청기 전문회사인 Starkey Hearing Technologies(Starkey) 사의 사례를 중심으로 장애보조기구인 보청기가 어떻게 스마트 기기의 범주로 들어오고 있는지를 규명하고 있다. 1967년에 설립된 Starkey는 형태 및 기능 등 보청기의 혁신을 주도하여 온 것으로 보이며, 최근에는 세계 최초로 인공지능 및 생체 센서를 탑재한 보청기를 출시하는 등 최신 4차산업혁명 기술들을 활용한 보청기를 출시하고 있다. 본 연구에서는 장애보조기구 전반과 Starkey를 대표로 하는 보청기, 그리고 스마트 웨어러블 기기와 스마트 이어폰의 발전 과정의 단계적 특징을 살펴보았으며, 최근에는 보청기의 기능이 단순한 장애 보조를 넘어서 장애인들의 엔터테인먼트 및 생활 보조를 위한 기능까지 확장되며 기존 스마트 웨어러블 기기와 장애보조기구 간의 경계가 붕괴되고 있는 것으로 나타났다. 이를 바탕으로 장애보조기구와 스마트 웨어러블 기기의 발전 모델을 도출하였으며, 변화되는 기기들에 맞추어 예상되는 사회 변화를 논하였다.

Binaural hearing aids with a voice transmitter have been widely used to enhance sound quality in noisy environment. However, this system has a limitation on sound-source localization. In this study, we investigated automatic directional-gain control method using geomagnetic sensors to provide directional information to binaural hearing aid user. The loudness gains of two hearing aids were differently controlled based on the directional information between a speaker position and a viewing direction of hearing aids user. This relative directional information was measured by two geomagnetic sensors on hearing aids user and a speaker. The results showed that the loudness gains were accurately controlled and could provide directional information based on the cue of interaural level differences.

Frequency transposition (FT) hearing system was designed for individuals with little or no residual hearing at high frequencies. This device compresses and shifts the wide-band, high frequency acoustic energy where important features for speech perception are concentrated to the audible, lower range of frequencies. The usefulness of the FT system was investigated for 12 patients (7 children and 5 adults) with severe-to-profound sensorineural hearing losses compared with conventional hearing aids. Results suggest that the hearing impaired can benefit from the FT system with appropriate selection criteria and auditory (re)habilitation program.
