最近Jones等提出机场产生的噪声强度,使居住在机场附近居民的子女发生先天性畸形。因此,作者汇集了亚特兰大市1970至1972年期间的有关资料作了类似的分析研究,即按照围绕亚特兰大机场的噪声强度昼夜加权平均数(Ldn,单位:分贝数/24小时)的等响线地图,将完全或绝大多数情况下处于65-Ldn等响线内的人口调查区定为高噪声区,而亚特兰大其余地区为低噪声区,然后将高、低噪声区的17种先天性缺陷的发病率及先天性畸形儿的总发病率进行比较。
Recently, Jones et al. Proposed that the intensity of the noise generated at the airport caused congenital malformations in children of residents living near the airport. Therefore, the authors have compiled a similar analysis of relevant data from 1970 to 1972 in Atlanta, that is, an isochord map weighted according to day and night weighted average noise intensity around Atlanta Airport (Ldn, in decibels / 24 hours) , The census area in the 65-Ldn siren is defined as a high noise area in all or most of the cases, while the rest of Atlanta is a low noise area, and the 17 congenital defects in the high and low noise areas Incidence and congenital deformity of the total incidence of children were compared.
