Since the eighties the formerly well established hearing screening performed at the age of four has been debated, partly for economic reasons. One quarter of Sweden's counties have since then abolished it. But how many children do we detect by this screening? What significance does it have for a child that those around it are aware of a mild hearing impairment? In Norrbotten, in all, we found 123 children born 1989-1992 with a hearing impairment. The prevalence was 7.9 per thousand. 30 percent of the children were detected at the 4-years hearing screening, and of these 0.9/1,000 had a hearing impairment that was bilateral, 1.0/1,000 unilateral and 0.5/1,000 impairment only in the high frequencies. Also children with mild bilateral or unilateral hearing impairment can experience difficulties in school and among friends, especially in noisy surroundings, and benefit by knowing early about their hearing impairment.
自八十年代以来，以前在四岁时进行的成熟听力筛查受到了争议，部分原因是经济因素。从那时起，瑞典四分之一的县已废除了这项筛查。但是通过这种筛查我们能检测出多少儿童呢？周围的人知晓儿童有轻度听力障碍对该儿童有什么意义呢？在北博滕，我们总共发现1989年至1992年出生的123名儿童有听力障碍。患病率为千分之七点九。30%的儿童是在4岁听力筛查时被检测出来的，其中每千分之0.9的儿童有双侧听力障碍，每千分之1.0的儿童有单侧听力障碍，每千分之0.5的儿童仅高频有听力障碍。患有轻度双侧或单侧听力障碍的儿童在学校和与朋友相处时也可能会遇到困难，尤其是在嘈杂的环境中，尽早知道自己的听力障碍会对他们有益。
