The State of art and Prospective of Intelligent Hearing Aid Technology with Mobile Communication Platform
Professor of Tsinghua University
Wang Zhihua, Professor of Tsinghua University, IEEE Fellow. Has long been engaged in research and development of medical devices based on electronic technology. As of December 2016, together with colleagues and students, 160 papers were published and cited by Scientific Citation Index, CI papers, 439 papers were presented at international conference, 7 US patents, and 121 Chinese patents were authorized, 11 books and/or book chapters were published as the academic monographs or text book. A few awards had been Issued to him for the contribution of progress in science and technology by provincial, municipal and national government authority. He has served as Chief Scientist of China Ministry of Science, and Technology Expert Committee Member, China 863 Program, in the area of Information Science and Technologies, an expert member of advisory committee of national Program for the development of kernel electronic components, high-end general-purpose chips and basic software products, and a Member, China Securities Regulatory Commission IPO Review Committee. He is currently an AdCom member of the IEEE Solid State Circuit Society.
According to the statistics from WHO (World Health Organization), the global disabled hearing loss patients has been 360 million, accounting for 5.3% of the population. With age, hearing loss gradually increased, about 1/3 of the elderly over age 65 there is disability hearing loss (moderate / heavy / severe). These people are difficult to communicate with people, affecting daily life and safety, leading to psychological problems such as loneliness, isolation and frustration. About 36.4% of dementia are associated with deafness. It is increased the risk of senile dementia about 3 to 5 times by moderate / severe hearing loss. Hearing aids are the most effective and practical way to help patients with improvement of hearing. It can customize the sound according to the hearing impairment characteristics, improves hearing and does not damage the residual hearing. Deafness and hearing aids can cause brain language processing capacity to decline, hearing loss accelerated. In year 2016, the global market of hearing aid equipment is about 15 billion US dollars, of which the sales of hearing aid manufacturers about 4.2 billion US dollars; the market of fitting retail is about 100 billion US dollars. The population of China is about 1.4 billion accounted for 18.8% of the world, but the annual sales of hearing aid accounted for only 4% of the world market. There are three main reasons for this phenomenon, the quality of sound processing inside hearing aids, price and fitting services. A new binaural hearing aid device is proposed in this report to utilize a mobile communication (computing) platform. The binaural sound information are used to improve the adaptability to the environment, and a mobile computing platform is used to implement the delicate algorithm and to reduce the size of the hearing aid equipment, and to simplify the listening test process, improve the quality of service and user experience.
