説明

Compairing two audiograms of the identical ear of one hundred and seventy normal subjects tested with 1 to 6 months interval, the limit of the natural error was studied. Distribution of the values obtained by subtracting the hearing threshold level of second audiogram from those of first was demonstrated. The means, standard deviations and rejection limits were calculated. In conclusion, the following values were proposed as the critical values for the decision of the hearing change, improvement or deteriorations, and it can be diagnosed that the hearing had improved or deteriorated when the values obtained by using the above mentioned manner exceed the followings.
