These innovations are complemented by features like TV mode and easy scene switching, catering to users who enjoy television and video calls, thereby transforming the hearing aid experience into one that is enjoyable and tailored to individual lifestyles.
However, the effectiveness of hearing aids is contingent upon proper fitting, a service that remains inaccessible to many due to logistical challenges such as travel distance, cost, and a shortage of professional centers. To bridge this gap, TEALab launched the Tencent Ethereal Audio Remote Hearing Service Platform, a groundbreaking initiative that enables users to access fitting services from the comfort of their homes. Through remote guidance by fitting specialists, thousands of hearing-impaired elderly individuals have already benefited from this service, underscoring the potential of tele-audiology in democratizing access to hearing health care.
In addition to improving traditional hearing aids, TEALab is leveraging advanced AI techniques to enhance speech understanding for those who rely on sign language. This includes the application of sophisticated models that accurately interpret speech, facilitating better communication for the hearing-impaired community. A testament to TEALab’s holistic approach to hearing health is their establishment of a special relief fund aimed at assisting hearing-impaired elderly in China. Nearly 5 million users have undergone hearing screenings through this initiative, with targeted relief provided to 500 seniors in the city of Shaoguan, illustrating a comprehensive strategy that encompasses early screening, diagnosis, treatment, and fitting.
