Hearing aid fitting is an act of repeating adjustment and evaluation of the hearing aid to find out the most appropriate hearing aid and amplification to the hearing aid users.
Re-adjustments are made referring to the user's experience of trial use of hearing aids, result of speech discrimination test and questionnaire to the users. However, though they could satisfied with hearting aid's amplification adjusted in relatively quiet environment, it is still difficult for many of hearing aid users to understand speech in everyday life than they expected and they may have doubts on efficiency of hearing aids.
In these days, the programmable hearing aids and digital hearing aids have been used like conventional hearing aids, and adjustable range of amplification has been remarkably improved. Those adjustments can be easily saved and also can be reproduced.
With a purpose of determining the appropriate programs of hearing aids which are suitable for various environment in everyday life and of their evaluation making a good use of those new functions, we have developoe a fitting support system with virtual environmental sound, called “FiVES”.
