Groundbreaking Nigerian Researchers Develop Affordable Locally-Made Hearing Aid



Researchers at the University of Ibadan in Nigeria have successfully developed an innovative hearing device called the “Chord Hearing Device.” This locally-made hearing aid, created by Dr. Adebolajo Adeyemo, Associate Prof. Bolanle Oladejo, and Dr. Oluwasola Adeniji, has garnered significant attention for its affordability and self-programming capabilities. The project was carried out under the guidance of the Tertiary Education Trust Fund Alliance for Innovative Research (TETFAIR), showcasing the potential of academic-industry collaborations in Nigeria.

Abdulmumin Oniyangi, the Acting Director of Public Affairs for TETFUND, announced that the Chord Hearing Device has been selected for exhibition at the prestigious Sheba ARC Global Entrepreneurship Programme. The researchers were chosen to participate in TETFAIR due to their groundbreaking solution, which addresses the challenge of accessible and affordable hearing aids in Nigeria. This recognition further validates their efforts in developing a device that can significantly improve the quality of life for individuals with hearing impairments.

The team of researchers has achieved substantial progress, reaching the completion of the first prototype of the Chord Hearing Device. The current phase involves user testing to assess its performance and refine any necessary adjustments, ensuring its effectiveness and usability. This proof-of-concept phase is crucial in demonstrating the device’s capabilities and validating its potential to meet the needs of the target users.

Dr. Adebolajo Adeyemo had the opportunity to represent the team at the ARC Program, an extensive 12-week initiative aimed at addressing pressing healthcare challenges. The program brought together 29 startups from various countries, including Israel, the United States, Germany, Japan, Colombia, Nigeria, South Africa, and Australia. By collaborating with experts and entrepreneurs worldwide, Adeyemo and his colleagues had the chance to showcase their innovation to investors and industry professionals.

The selection of Dr. Adeyemo among the 11 healthcare researchers chosen from five continents to present their innovations at the final event of the Sheba ARC Global Entrepreneurship program in Israel speaks volumes about the potential impact of the Chord Hearing Device. His innovation, coupled with a compelling pitch, secured his spot as one of the three startups selected to present at the ARC Global Summit in Tel Aviv on June 14, 2023.

The Chord Hearing Aid, along with other groundbreaking solutions developed by Nigerian researchers, will be prominently displayed at TETFAIR’s final event at Innov8 Hub in Abuja. This exhibition aims to showcase the advancements made by local researchers and highlight the potential for further innovation and collaboration within the Nigerian healthcare sector.

The success of the Chord Hearing Device and its recognition on a global platform not only reflects the dedication and expertise of the researchers involved but also emphasizes the importance of investing in local research and development. By fostering an environment that supports innovative projects like this, Nigeria can address critical healthcare challenges and improve access to essential medical devices for its population. The Chord Hearing Device stands as a testament to the capabilities of Nigerian researchers and their commitment to making a positive impact on society, one innovation at a time.
