Of the Dutch school population 0.1% suffer from a hearing loss which makes it necessary for them to attend a special school. This permanent, binaural hearing impairment is of a moderate to severe degree (degrees II and III) and adversely affects the child's linguistic skills and school performance. Of the pupils attending ordinary schools 4-5% suffer from a hearing loss which, according to the Dutch audiologist Huizing, lies on the borderline of a slight to moderate hearing impairment (degrees I and II). This loss is characterised by its temporary nature, the fact that it is monaural in 71% of the cases and that there is no evidence for its clearly affecting the learning process. The risk of hearing impairment is predominantly determined by the child's family background.
在荷兰学生群体中，0.1%的人患有听力损失，这使得他们有必要进入特殊学校就读。这种永久性的双耳听力障碍为中度至重度（二级和三级），会对孩子的语言技能和学业表现产生不利影响。在普通学校就读的学生中，4%至5%的人患有听力损失，据荷兰听力学家胡伊津称，这种听力损失处于轻度至中度听力障碍（一级和二级）的临界状态。这种听力损失的特点是具有暂时性，71%的病例为单耳听力损失，而且没有证据表明它会明显影响学习过程。听力障碍的风险主要由孩子的家庭背景决定。
