19 Individuals with hearing loss and their families may also utilise other skills to support language development and communication in place of or in combination with hearing aids. This could include the use of sign language, such as American or British, Australian and New Zealand Sign Language, International Sign or Manually Coded English, natural gestures, speech reading, finger spelling, listening or auditory training, and spoken speech.

22 The W.H.O. analysis suggests that annual cost of unaddressed hearing loss is in the range of $750-790 billion (in 2015 international dollars) with $67-107 billion attributed to costs in the health-care sector, $3.9 billion estimated cost to the education sector of providing support for children with unaddressed hearing loss, $105 billion due to loss productivity from unemployment and premature retirement and $573 billion attributable to societal costs of social isolation, communication difficulties and stigma.

39 A telecoil picks up signals from an audio induction loop systems or F.M. radio system to stream amplified sounds directly to the hearing aid. Telecoil facilities are critical to increasing compatibility with other assistive technology. Loop systems are often found in concert halls, universities, and other public spaces to support hearing in noisy or large spaces.
