Changing systems of amplification

This paper reports on the changing systems of amplification used by hearing-impaired children in the last decade (1977 to 1987). The major changes noted were in terms of ear-level v. body-worn hearing aids, monaural v. binaural hearing aids and FM-wireless v. hardwire group hearing aids (GHAs). There was an increase in the use of ear-level hearing aids, binaural hearing aids and FM-wireless hearing aids with a corresponding decrease in the use of body-worn hearing aids and hardwire GHAs.
