“…The median thresholds at 4 klz are generally about 3 dB higher than those at 1 kHz (D4 in tables) which may be due to the effects of noise. These results are similar to those from some earlier reports that hearing sensitivity tends to increase with age in children (Black, 1939;Reymert and Rotman, 1946;Kennedy, 1957).…”

The document is a review of information which deals directly and indirectly with the effects of noise on children. Potential problem areas are identified and recommendations for research are stated.Subject Classification: 10.60; 50.70; 65.10. gins in the first few months of life and appears to be a continuous process. Indeed, because of the large amounts of pathology observed in the cochleas of young children, fetal material has been used to define a full complement of sensory cells (Bredberg, 1968). While the age-dependent degeneration of the sensory cells has been studied in some detail, the effects of age on cochlear circulation, metabolism, mechanics, and mem• brane configuration have not. Since all of these factors are involved to some extent in the production of injuries to the inner ear and noise-induced hearing loss, it is thus difficult to generate substantive, a priori predictions about the effects of age. Concern with noise-induced hearing loss in childrenis not an academic issue. A number of devices used directly or indirectly by children have sound levels which are capable of producing an acoustic injury to the adult ear and temporary, chronic, or permanent hearing losses. The likelihood of injury and hearing loss, however, depends upon the duration of the exposure, the number of exposures, the scheduling of exposures, as well as the relative susceptibility of the individual child. Devices with notably high sound levels include firecrackers (see Ward and Glorig, 1961), model airplane engines tested indoors (Bess and Powell, 1972), snowmobiles (Bess and Poynor, 1972, 1974; Chaney et al., 1973), real and toy firearms (Marshall and Brandt, Redistribution subject to ASA license or copyright; see http://acousticalsociety.org/content/terms.

Devices which produce high-level, impulsive sounds create the greatest risk (firecrackers, for example), as just one exposure can produce a large, permanent hearing loss (see Ward and Glorig, 1961). Devices which produce moderate levels but to which persons are exposed for long durations without rest periods or with very short rest periods also create a risk of hearing loss and injury to the ear. Rest periods away from excessive noise are one means of protecting the ear from injury and hearing loss. All-day outings on snowmobiles and the placement of premature and unhealthy infants for weeks in incubators and pressure boxes (see also Sec. I-G) are the most obvious examples. Additional details of noise-induced hearing loss in children are discussed below. B. Permanent hearing lossesGiven the spectrum of the noise used by Falk et al., one would predict from human, chinchilla, cat, and monkey data that injuries would be maximal towards the base of the cochlea, turn 1, and minimal toward the apex, turns 2-3. They report just the opposite. It is thus conceivable that the effects ob...
