At the IFHOH 4th conference about hearing loops and technology held in Berlin, October 6-8, 2017, a proposal was made for the formation of a Steering Committee.  The Committee was established in 2018 and has held several meetings by internet. 


The aims of the Committee are:

  1. To foster a greater understanding and awareness of the benefits of accessible technology and sound systems for persons with hearing loss with particular attention paid to hearing loop technology

  2. To further developments for hearing technology and hearing loop technology use and availability as well as continual improvements in technology

  3. To foster improved telecoil function and innovative application and raise awareness of its benefits among the providers in the hearing industry providers. 


Objectives are:

  1. To develop a strategic plan for the development and promotion of hearing technology including hearing loop technology worldwide.

  2. To develop a mapping plan of existing technology and resources

  3. To assist IFHOH in the planning for the next Future Loops and Technology event/conference.


The scope of the work is recognized to encompass a wide audience: consumers, advocates, audiologists, hearing aid and cochlear implant industry providers, sound engineers, architect, audio/visual designers and installers, facilities covered by disability laws, accessibility committee, manufactures of assistive listening systems, and others interested in this technology.

The Committee has a steering committee of six consumer and professional representatives.
