Excessive sound may cause deafness in infants. The American Academy of Pediatrics has suggested that incubator noise levels not exceed 58 decibels on the A scale. Noise levels in a neonatal intensive care unit were investigated. Ambient noise was 57 dB. Incubators produced 55 dB, respirators 58 to 59 dB, and one brand of pneumatic nebulizer created sound of 85 dB. The latter was unacceptably far above the current maximum standard of 58 dB and use of the nebulizers was discontinued. Manufacturers and users should investigate the noise-producing characteristics of all devices used in clinical care.
