AN EVALUATION OF PATIENTS SUSPECTED OF HAYING NOISE-INDUCED HEARING LOSS

摘要

The results of an evaluation of 77 U. S. Air Force flight-line personnel with defective hearing are reported. The evaluation revealed that 29 patients had a conductive-type, 7 had a functional-type, and 41 had a perceptive-type defect. Twenty-two of these perceptive cases were unilateral. In only 19 cases was noise exposure considered to be a possible cause of defective hearing. The difficulties encountered in attempting to determine whether defective hearing in a specific patient is caused or aggravated by noise exposure are discussed.
