World Wide Hearing

World Wide Hearing is developing an inexpensive tool for health workers to screen for hearing loss anywhere.


Research suggests that 95% of people with hearing loss can be treated with hearing aids, but less than 1% of people in low- and middle-income countries who need hearing aids get them. Part of this is due to the lack of effective diagnostic and treatment options.


World Wide Hearing is developing an affordably-designed, smartphone-based hearing loss diagnostic tool for use in the developing world. The new product will substantially cut costs compared to existing diagnostic methods.


The diagnostic tool will be piloted with World Wide Hearing’s network of partners and social enterprises to screen at least 10,000 at-risk beneficiaries for hearing loss over the next two years. Ultimately, this technology has the potential to reach hundreds of millions more when used by other healthcare workers.
