Application of regression analysis to examination of degree of loss of hearing.

The present study is an attempt to apply analysis of regression for the purposes of evaluation of loss of hearing. This method consists in calculating equations of regression for relation between the age of the examined people and the degree of elevation of the hearing threshold for various frequencies. The slope of the regression line allows to conclude about the degree of damage to hearing. Practical application of this method was shown with an example of a study on the status of hearing in workers of several manufacturing departments of a pottery plant.
