Pagination or Media Count:
Speech-to-babble ratios for 50 word recognition were measured in four men, age 30 to 35, while breathing 12 and 21 oxygen. There were no differences between the two conditions. Learning effects, however, were seen for the task. As the 12-oxygen level is considerably lower than would be used for routine reduction of fire hazards onboard submarines, reduced oxygen levels at the intermediate levels being considered should not affect speech recognition. Keywords Background noise.
