The customer is a North American start-up company offering cloud-based telephony services. They started out as a team of professionals with deep domain knowledge in digital signal processing and sonic clarity. The customer’s primary goal was to bring to market the best-in-class communication solution for people with partial hearing loss.
The MERA team was involved in a groundbreaking project aimed to enable people with hearing loss to communicate via their smartphones and computers using ordinary headphones as a substitute for hearing aids.
The app was to perform a short assessment of individual hearing characteristics automatically making personalized fine-tuning and adjustments. After that, all incoming audio media would be modified to enhance the sound clarity and speech understanding.
Having their own resources for mobile apps development, the customers wanted MERA to take over all the backend and web client development. The project requirements included a number of third-party open source solutions to be used, which resulted in certain complications for MERA engineers.
The project execution commenced with developing a cloud server solution for the hearing app from scratch. It involved a team of MERA experts with a wide scope of experience in backend development for the telecommunication industry.
One of the challenges the team faced was performing integration of the service with several open source solutions. Some of them caused significant problems with the audio quality which degrades during various types of network disturbances. Therefore, MERA had to introduce numerous changes in the third-party source code apart from developing the cloud PBX solution. Ultimately, our professionals succeeded in fixing the issues.
The MERA team has developed a web client with a modern and easy-to-use interface, meeting all the requirements and expectations of the customer. Keeping pace with current technology trends, the customer continues to expand the functionality of the product with the help of MERA specialists. One of the latest features implemented by our engineers is Voicemail.
Currently, MERA is involved in improving and simplifying the backend infrastructure of the product by implementing alternate architecture solutions such as migrating the system to a different cloud-based platform with proprietary protocols.
From the very beginning, the app was highly appreciated by people with all types of hearing loss and by health professionals. Due to the unique sound clarity and rich functionality, it remains a one of a kind solution creating unparalleled opportunities for the end-users. Still, the customer is planning to further improve it by adding new features within the scope of an ongoing product enhancement.
A successful launch to the market allowed the customers to attract new investors for further product development and company growth.
