Objectives : The purpose of this study is to report the case of a presbycusis patient whose hearing had improved. Methods : A 81-year-old male diagnosed with presbycusis were treated with Korean medical interventions (acupuncture combined with electromagnetic stimulation and pharmacoacupuncture) and Threshold sound conditioning(TSC) for 3 months. Pure tone audiometry(PTA) was performed for the evaluation. Results : The patient's hearing was improved from moderate to mild level according to the Classification of Hearing Loss(International Organization for Standardization, 1969). The average hearing were improved from 40.5 dB to 32.7dB on the left side, 46.9dB to 34.1dB on the right side. Conclusions : We observed an improvement in a presbycusis patient's hearing and hereby suggest the possibility of Korean medical treatment and TSC's ameliorating effect on sensorineural hearing loss as well as prebyscusis.

Presbycusis or related-age hearing loss is approximately 30 percent for people aged over 65 years. The purpose of this study was to compare the relationship between the Hearing Handicap Inventory for the Elderly and the Berg Balance Scale for predicting and screening risk of falls in people over 65 years with diagnosed presbycusis. Thirty-five subjects all lived at the nursing home in Wonju. Disability caused presbycusis was measured using the Hearing Handicap Inventory for the Elderly, and static and dynamic balance was measured using Berg Balance Scale. Data were analyzed using Spearman correlation. Statistically significant differences were noted between two clinical meausres (r=.862, p<0.001). In conclusion, the results suggest that presbycusis may be able to predict dangerous falls in older persons.

In this paper, we improved the high frequency noise characteristics of the previously proposed hearing aid circuits for presbycusis, and we designed and fabricated a stereo hearing aid module. The cause of high frequency noise, which occurs in some cases in the previous circuits under high gain conditions, was analyzed through simulations. Two mute switches were added to adjust each boosting gain for right and left ears more accurately by muting the sound of the other ear when adjusting the gain of one ear in the stereo hearing aid module.

Everyday hearing handicap caused by presbycusis ultimately reduces quality of life in older adults. The aim of this study was to explore effects of cognitive impairment on self-reported hearing handicap in older adults with early-stage presbycusis. We compared K-HHIE scores between 40 elderly subjects with mild cognitive impairment (MCI) and age- and hearing-threshold matched 40 cognitively normal elderly (CNE) subjects. The results are as follows: 1) The MCI group scored significantly higher than the CNE group on the social/situational and emotional sections, and in total. 2) The MCI group scored significantly higher than the CNE group on all four subscales, and the most significant group difference was on the first subscale relating to interpersonal relationships and social handicaps. 3) Both groups scored highest on the item 8 (problems hearing whispering sounds) and item 15 (problems hearing TV or radio sounds). Besides those two items, the MCI group also scored high on the item 21 (problems hearing in a restaurant), item 6 (problems hearing when attending a party), item 3 (avoiding groups of people), and item 20 (personal or social restrictions). Our findings suggest that, among older adults with early-stage presbycusis, older adults with cognitive impairment tend to report greater everyday hearing handicap than their peers with normal cognitive function. Especially, they show significant problems hearing in background noise or multi-talker situations, which cause social restrictions and social/emotional loneliness.

Objectives : This study was conducted to approve the effectiveness and safety of herbal medicine on presbycusis with kidney deficiency. Methods : We searched randomized controlled trials(RCTs) on presbycusis patients diagnosed with kidney deficiency through 10 electronic databases from the start to Sep 7, 2021. Study collection and data extraction, and evaluation of risk of bias were conducted by two independent collaborator. The evaluation of the risk of bias in included RCTs was carried out by using Cochrane risk-of-bias tool. And the data synthesis was conducted by using Review Manager(RevMan, ver.5.4). Results : 1. The treatment group which used herbal medicine(HM) alone was more effective than the control group which used only western medicine(WM) on effective rate of hearing loss. 2. In 3 studies comparing the HM-WM combination treatment group with the control groups using the same WM treatment, the effective rate was statistically significantly higher in the HM-WM combination treatment group. 3. Of the 5 studies that reported adverse reactions, one study reported mild nausea and dizziness, but the difference between the HM treatment group and the WM control group was not statistically significant, and no side effects occurred in other 3 studies. 4. In studies comparing HM and WM, the HM treatment group improved hearing loss, whole blood viscosity, serum TNF-𝛼, IL-1𝛽, IL-6, and oxidative stress indicators better than the WM control group, and there was no significant difference. 5. In studies comparing the HM-WM treatment group with the WM control group, the severity of tinnitus, quality of life, and feelings of anxiety and depression were better in the treatment group than the control group. Conclusions : This study shows that the herbal medicine can improve symptoms of presbycusis with kidney deficiency.

Objective: The aimes of this study is to analyze the effects of presbycusis on the quality of life. Method: 47-elderly were participated. The participants were divided into the suspected hearing impaired group (N=18) and the within normal limits (WNL) group (N=29). One-way ANOVA was performed to determine the association between the HHIE and WHOQOL-BREF scores by age group, and independent t-test was carried out to analyze the inter-group relations. Results: The scores in WHOQOL-BREF differed significantly by age group (p=.011): people in their sixties scored $3.7{\pm}.62$, those in their seventies $3.3{\pm}.56$, and those in their eighties $2.8{\pm}.60$, with significant differences observed. There were statistically significant inter-group differences (p=.000), with significant differences observed. Conclusion: The quality of life of the elderly were lowered depending on age and hearing impairment.

노인성 난청(presbycusis)은 나이가 들어감에 따라 청력이 점진적으로 악화되는 것으로 성인 난청의 가장 흔한 원인중 하나이다. 미국과 마찬가지로 국내의 여러 연구에서 보면, 65세 이상의 노인 중 보청기를 착용해야 할 정도의 난청이 있는 비율이 전체의 30~35% 정도를 차지하고 있다. 이렇기 때문에 노인성 난청은 노인성 만성 질환 중 퇴행성 관절염, 고혈압에 이어 3대 만성 질환으로 분류되고 있다.

In order to realize the function of human interface of telecommunications whose objective is to interchange useful information among persons, we developed a bone conduction telephone with which hearing impaired persons with conductive or noise-induced hearing loss and presbycusis can communicate with each other without any other additional devices such as hearing aids. The bone conduction telephone we developed has chatacteristics as follows : (i) a hearing impaired person and a normal hearing person can communicate by bone and air conduction hearings, respectively, using only this telephone set because, as its receiver, it uses a bone conduction vibrator with which we can realize such function with the voice coil and damper of a small speaker unit, the vibrating plate, etc., (ii) it has tone control function compensating hearing losses of hearing impaired persons according to their hearing loss/frequency chatacteristics. Using the tone control function together with a received volume control, it has the received volume range of 20dB in loudness rating; and (iii) it has the function of three emergency calls and a bell lamp as the visual display of a received call.

In this paper, the analysis of the relation between noise induced hearing loss and noise exposure is described for the A-weighted noise levels and exposure duration. The hearing loss and sensitivity threshold shift is investigated by changing the various parameters such as the effects of aging and noise exposure. Total hearing loss is proportional to a function of exposure level based upon the integral of pressure with time. If the noise exposure term is large so that the presbycusis may be neglected, the hearing loss due to aging and noise exposure becomes the noise induced hearing loss. It is shown that exposure to excessive noise can cause temporary loss of hearing that may become permanent if the exposure is prolonged or intense. An audiogram taken from a person suffering from noise induced hearing loss will usually show the greatest loss of hearing sensitivity in the 4kHz region, which is typically the region most sensitive to damage resulting from many types of industrial noise.
