“…Other reports gave incidences of 4-15 % (Campanelli et al, 1958;McDonald, 1964) for babies of short gestations and very low birthweights, but these figures were either based on selective assessments or were derived from selected groups of deaf children. Thus it is difficult to know if they represent maximum or minimum estimates.…”

“…Douek et al (1976) suggested that this might be due to damage of the cochlea by ambient noise from the incubators in which these infants are usually nursed. To support this suggestion they quoted a study by Campanelli et al (1958) which showed that the mean length of stay in incubators for low birthweight infants with sensory neural loss was significantly longer than the mean for low birthweight infants without hearing loss. There were, however, other important differences between the two groups.…”

“…The incidence of potentially lethal or damaging perinatal complications increases as birthweight and Ear, Nose and Campanelli et al (1958) who had sensory neural hearing loss are much more likely to have suffered brain damaging complications than the heavier infants without hearing loss. Perinatal complications are also likely to influence the length of incubator stay.…”

SUMMARY The hearing of 111 perinatal intensive care survivors of birthweights 1500 g or less was assessed at a mean age of 64 years (range [4][5][6][7][8][9][10][11][12]. These 111 infants included 86 % of the longterm survivors of this birthweight cared for in the newborn unit of University College Hospital, London, during the years 1966-72. All these infants were nursed in commercially available incubators for periods ranging from 2 to 80 days (mean 37) in which the mean noise threshold was 65 dB. Ten (9 %) had sensory neural hearing losses, one (1 %) infant had a congenital conductive hearing loss, and 21 (19 %) infants had exudative otitis media with a mean loss of 25 dB. Apnoeic attacks in the neonatal period were the most significant predictors of hearing loss in these infants (P<0 .05) and an indirect serum bilirubin level of at least 170 pumol/l (10 mg/100 ml) in the neonatal period had an additive effect (P<0 .05). There was no evidence that ambient noise had affected the hearing of these very low birthweight infants.Reports indicate that the incidence of sensoryneural hearing loss among very low birthweight infants is high (4 to 15-9y%) (Campanelli et al., 1958;McDonald, 1964). Douek et al. (1976) suggested that this might be due to damage of the cochlea by ambient noise from the incubators in which these infants are usually nursed. To support this suggestion they quoted a study by Campanelli et al. (1958) which showed that the mean length of stay in incubators for low birthweight infants with sensory neural loss was significantly longer than the mean for low birthweight infants without hearing loss. There were, however, other important differences between the two groups. In particular, the mean birthweight in children with sensory neural hearing loss was only 981 g, whereas the mean for the children without hearing loss was much greater-1718 g (P<0 05).

“…Characteristically the audiograms showed moderate or severe high frequency loss with never more than moderate low frequency loss. Campanelli, Pollock and Henner (1958), in a study of 44 children aged 6 years who had been admitted to a premature baby nursery, found high frequency deafness in 7 (16%); 44 children weighing over 51 lb. (2,500 g.) at birth had normal hearing.…”

We retrospectively investigated the influence of gestational age, perinatal risk, and the duration of incubator care periods in 193 surviving preterm infants with a gestational age between 28 and 36 weeks raised in our intensive care nursery incubators from 1965--1967. 24 (12.4%) of the children showed definite neurosensory hearing defects, which were particularly encountered in the high frequencies. No correlation could be substantiated between hearing difficulties and hyperbilirubinemia, streptomycin application and gestational age. This study does not support the assumption that the duration of noise exposure in currently used incubators is a major determinant for the development of deafness in otherwise healthy preterm infants. Our study did show, however, a strong correlation between the sum of all perinatal risk factors and neurosensory hearing loss.
