Male patients of two hospitals in Belo Horizonte completed a questionnaire during an interview on the day of discharge in order to evaluate sleeping conditions related to noise during the previous night and were retested 24 h later. Patients had a worse perception of sleep at the noisier hospital, the University Hospital of the Federal University of Minas Gerais (N = 13), whose internal mean nocturnal noise level was Leq = 53.7 db(A), than at the quieter hospital, Baleia (N = 22), whose internal mean nocturnal noise level was Leq = 45.5 db(A). Noise was the only sleep-disturbing factor which was statistically significant.
贝洛奥里藏特两家医院的男性患者在出院当天接受访谈时填写了一份问卷，以评估前一晚与噪音相关的睡眠状况，并在24小时后再次接受测试。在噪音较大的米纳斯吉拉斯联邦大学大学医院（N = 13），患者对睡眠的感知较差，其夜间内部平均噪音水平为Leq = 53.7分贝（A），而在噪音较小的巴莱亚医院（N = 22），其夜间内部平均噪音水平为Leq = 45.5分贝（A）。噪音是唯一具有统计学意义的睡眠干扰因素。
