包括2000名新生儿的声学调查表明，与早期调查一样，儿童甚至在出生后的第一个半小时内也能听到声音。耳睑反射阳性率为96.1%。在0.6%的反射是可疑的，在3.3%是阴性的。除5例为早产儿外，所有病例迟早均呈阳性。其中4只在出生后第二天死亡。第五个孩子现在3岁了，听力有严重的缺陷，我们检查了66例出生时不能获得反射的病例，没有发现任何确切的分娩损伤。此外，除了大量的早产病例外，没有其他值得注意的地方。在几乎一半的早产儿中，分娩时没有声学反应。在48小时后反射仍为阴性的病例中，早产儿的数量为68.7%。
The acoustic investigation, which comprises 2000 newborn infants, has shown, as in earlier investigations, that a child can hear even during its first post-natal half-hour. 96.1% had positive auropalpebral reflex. In 0.6% the reflex was doubtful and in 3.3% it was negative. Sooner or later all cases became positive with the exception of 5 which were premature. Of these, 4 died on the second day after birth. The fifth, which is now 3 years old, has a serious hearing defect.When one examines the 66 cases in which a reflex could not be obtained at birth, no sure delivery injuries can be detected. There is, moreover, nothing else remarkable except the large number of premature cases. In almost half of all surviving prematures, no acoustic reaction could be obtained at delivery. In the cases where the reflex was negative even after 48 hours, the number of prematures was 68.7%.
