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.
