在以前关于社区噪音和儿童血压之间关系的研究中，很少使用夜间噪音暴露，尽管儿童比成人在夜间睡在家里的时间更长。因此，我们将重点放在儿童住宅的夜间噪声暴露和幼儿园的白天噪声暴露上。本研究的目的是调查城市道路交通噪声对儿童血压和心率的影响。对贝尔格莱德10所公立幼儿园的328名3-7岁学龄前儿童（174名男孩和154名女孩）进行了一项横断面研究。等效噪声级（Leq）进行了测量，在夜间在前面的儿童的住宅和白天在前面的幼儿园。住宅被认为是嘈杂的，如果Leq超过45分贝（A）在夜间和安静，如果Leq是：5 - 45分贝（A）。噪声和安静幼儿园为每日Leq>60 dB（A）的幼儿园，
Night time noise exposure has very rarely been used in previous studies on the relationship between community noise and children's blood pressure, although children spend a larger part of their night time sleeping at home than adults. For this reason, we focused on night time noise exposure at children's residences and daytime noise at kindergartens. The aim of this study was to investigate the effects of urban road-traffic noise on children's blood pressure and heart rate. A cross-sectional study was performed on 328 preschool children (174 boys and 154 girls) aged 3-7 years, who attended 10 public kindergartens in Belgrade. Equivalent noise levels (Leq) were measured during night in front of children's residences and during day in front of kindergartens. A residence was regarded noisy if Leq exceeded 45 dB (A) during night and quiet if the Leq was :5 45 dB (A). Noisy and quiet kindergartens were those with daily Leq>60 dB (A) and
