The choice of a method for volume control adjustment in hearing aid usage presents serious problems.
For the purpose of determining standard use of a hearing aid by young hearing impaired children, a series of investigations regarding the volume control adjustment of a hearing aid was conducted on 49 hearing impaired children who are now in normal class with hearing aid usage.
We concluded as follows.
(1) It is advisable that the aided threshold for pure tone does not exceed 40dB at 500, 1000Hz, and 60dB at 2000, 3000Hz
(2) Hearing aids should be used positively with suitable volume control adjustment and periodical audiological follow up.
