Volunteers are the backbone of the foundation

The Hear the World Foundation has a global volunteering program in which Sonova Group employees and selected external experts support our project partners worldwide. In the year 2022/23 volunteers performed a total of 1,320 hours of work on 59 assignments over 160 days.


The Sonova Group’s global volunteering program provides needs- and skills-based support in the areas of audiology, strategy, operations, and communications and marketing, thus promoting professionalization and knowledge building among our local partners. The following examples highlight this approach.



Since 2011, the Hear the World Foundation has supported the African Bible College in Lilongwe with training audiologists. The foundation was able to recruit four Sonova employees from Australia, New Zealand and Switzerland to revise course materials and teach online. Eight BSc students took advantage of the offer.


El Salvador and Cambodia – STRATEGY

The foundation now offers support from volunteers in the area of strategy. Sonova employees support one project team each, in El Salvador and Cambodia, and are developing business plans to help local partners function more independently in the future.



A cloud warehouse engineer from Sonova Canada developed a program that enables the collection and management of patient data along the entire supply chain, improving reporting to the foundation. The application will be used in other projects in the future.



A Sonova employee from Brazil, himself a cochlear implant user, visited the aid project in Peru together with the director and the program manager and documented this with photos and videos, which are now used for communications related to this project.


Data for the future 


Data collection along the entire hearing health value chain is one of the Hear the World Foundation’s strategic goals. A 35-year-old cloud warehouse engineer from Sonova Canada developed a program that enables the collection and management of patient data along the entire supply chain, improving reporting to the foundation.

What is the challenge in programming such a database?

The task entails comprehending the business process driving the data, constructing the database, and quickly acquiring the necessary programming skills.


What benefit does the foundation derive from the data?

To gain insight from previously paper-based data that are now centralized in the database, which allows a more thorough management of activities.


You spent twice as much time as budgeted. What is motivating you?

I have in mind those who will reap the benefits from this project.
