  • Abstract
  • Look Inside

 An audiologic screening test is conducted on 180 infants who were less than 1 year of age by means of neo-meter that emitted warble tone of 3,000 Hz (70-100dB S. P. L.). The results were as follow: (1) The reaction to this stimulation among infants less than 6 months old seemed to be rather poor, but those over and above 7 months showed a satisfactory response in 93% of cases-therefore, if the response in an infant mor than 7 months appeared questionable, presence of hearing impairement may be suspected that will need a further inquiry.

 (2) The test is apt to be unsatisfactory at the time when the infant appear to be indisposed which should be avoided.

 (3) Various criteria are employed. For infants up to 3 months of age Moro's response and eye responses are used; beyond the 4th month the head turn should be considered as the chief criteria.
