The technology available to deaf or hard of hearing people is progressing at an amazing rate.
Compared to the hearing aids of a few decades ago, hearing aids for both adults and children now are incredibly tiny and high-tech, with the ability to direct sound, to filter background noises and to connect wirelessly to other devices.
The introduction of the cochlear implant has added another facet to the technology available, and with such tools as FM systems, iPads in schools and sound-field systems in classrooms, deaf or hard of hearing children have far better access to education in mainstream schools.
