Audiometric methods for the detection of hearing loss are often based on the comparison of measurements with standard curves representing 'normal' hearing. These methods suffer from large inter-individual variances in middle-ear transmission and from the individually very different collaboration of the patients, in particular of small children, seriously ill or elderly patients. Thus, the specificity of current diagnostic tests on a particular clinical picture as well as the quantitative evaluation is strongly restricted. This holds true especially for differential diagnosis between inner-ear and neural impairments since the middle-ear comes first in the measurement chain. The author suggests a model-based approach based on objective measurements, e.g. wide band tympanometry. Several numerical middle-ear models are known in hearing research, but by now do not contribute to individual, patient-specific diagnostics. Their use could increase the specificity of routine diagnostic tests on common middle-ear diseases and would allow an objective quantification of the individual pathologies.
