title: Understanding history, philanthropy and the role of WHO in provision of assistive technologies for hearing loss.
abstract: Philanthropy continues to play an important role in provision of hearing devices and is often the only alternative for the majority of those in need of these devices. While this leads to improved access to services it may also create unsustainable service delivery models. Over the past decade, World Health Organization (WHO) has been making consistent efforts towards promoting accessibility and affordability of high-quality hearing devices, especially in Low- and Middle-Income Countries (LMIC). WHO developed and updated the "Guidelines for Hearing Aids and Services in Developing Countries", in 2004. In 2006, WHO supported the establishment of "World Wide (WW) Hearing", to promote hearing aid access across the globe. In the past year, WHO has renewed these efforts. As the first step and following a consultation on promoting access to hearing devices, WHO has developed a preferred product profile in order to facilitate the development and access of appropriate and affordable hearing aids for developing countries. The Convention on the Rights of Persons with Disabilities (article 32), calls for international collaboration to promote access to assistive technology including hearing devices. A coordinated global effort is required to promote availability and affordability of high-quality hearing devices. Such an undertaking requires the cooperation of all stakeholders: WHO, Member States, Non-Governmental Organizations (NGOs), philanthropists, manufacturers and users, to fulfill the international obligation and bring about a change in the quality of life of millions of people with hearing loss.
  
  
  CONCLUSIONS
  Development of preferred product profile for hearing aids in LMICs can improve development and provision of high-quality, affordable hearing devices. Investment made by the recipients, such as partial financial contribution towards the cost of device or through purchase of ear mould or batteries, leads to a greater sense of responsibility towards the device and its maintenance. Low level of awareness about hearing loss and the potential benefits of hearing aids contribute to the underutilization of hearing aids.
