Clinical Populations

We are pleased to respond to Dr. Gluckman's thoughtful comments regarding our article, which is concerned with applying the objective methods of acoustic impedance measurements to pediatric clinical populations. Dr. Gluckman specifically asks if acoustic impedance measurements are practical for evaluating the "struggling, toxic infant with acute otitis media, or the infant who is frightened and struggling and has serous otitis media." Impedance measurements are objective because no behavioral responses are required of the patient.

Acoustic Resistance

An objective acoustic method is suggested for diagnostic examination of the ear. It provides supplementary information to the otoscopic and audiometric examinations. The acoustic method is based on impedance measurements at the eardrum by means of an acoustic bridge that is calibrated in absolute acoustic resistance and compliance units. The obtained values can be read directly on the instrument dials and no time consuming computations are required. The article includes an explanation of the concept of acoustic impedance, an analysis of the middle ear mechanism and of the acoustic effects of middle ear pathologies, in addition to a description of the suggested method.
