We have one of the lastest equipment for hearing aids assessment.
The batteries must be new as possible.
There must not be any wax or secretions or any material in external auditory canal to have an accurate assessment.
If their was insatisfactory aided responce we reprogram the hearing aid and must wait for 2 weeks before retesting.
The calibration of the used equipment is crusial for accurate assessment.
