[Relations between the discriminatory curve in the speech audiogram and tone audiometric measurement data (author's transl)].

The authors used the multiple linear regression model to describe the relationship between tone and speech hearing in noise induced hearing loss. The authors believe that these mathematic relations are significant for the expert opinion of noise induced hearing loss. Considerable discrepancy between the measured and calculated value might be simulation, aggravation or central disturbances. In these cases ERA should be applied.
