As a foundamental examination on the possibility of audiometry to new-born infants, both respiratory changes recoded on the kymograph (pneumogram) and other responses to auditory stimuli which contain the pure tone (500cps) and the imitation sound of animal (mooing) were investigated.There was no significantly different effect between the pure tone and mooing. The majority of the infants showed some responses to auditory stimuli at intensity of 40-80db above the audible threshold of healthy adults. The most prominent and frequent responses were temporary appearanceof big wave on the pneumogram and responses such as blinking and body startle.
