Respiration audiometry.
Since 1971 an impedance-plethysmographic method was been used to record changes in the breathing pattern of 218 high-risk infants during acoustic stimulation. The results of this technique, known as respiration audiometry, show that acoustically induced changes in the breathing pattern can be used as a hearing test for very young children. The results fall into four categories: excellent readability (45%), good readability (32%), readable (15%), not readable (8%). Respiration audiometry makes it possible in most cases to ascertain a child's hearing level. The neonatal period and early infancy are the ages best suited for investigations with respiration audiometry. The reliability of this method was found to be good.

Auditory function after Haemophilus influenczae meningitis.
Eighty-three children, having recovered from Haemophilus influenzae meningitis, were examined with audiometrical tests. Fifteen of the children (18.1%) had significant hearing loss. Bilateral severe hearing loss was found in 3 patients. Three patients had severe hearing loss affecting one ear and slight or moderate hearing loss affecting the contralateral ear. Six children had entirely unilateral severe hearing loss. Bilateral or unilateral slight or moderate hearing loss was found in 3 patients. The remaining 68 patients had normal pure tone average. Half of these patients, however, showed minimal hearing impairment at the low and high frequencies.
