Four different procedures, Jerger formula, Niemeyer-Sesterhenn formula, Baker-Lilly formula and bivariate plotting method (Silmon et al.), used in predicting hearing level from the stapedial refrex threshold data were compared from 63 normal hearing and 66 hearing impaired ears. With each method, hearing level was correctly predicted in more than one half of all ears, and predictive errors occured in only 2% of them. However, these methods showed a low rate (23-35%) in accuracy predicting a mild or moderate loss. Among these methods, the Jerger method suggested to be adequate to predict the severity of hearing impairment for younger children.
