Audiograms in the 0.5-6 kHz frequency range were taken, using improved audiometric screening methods, in 2032 children, 6-7 years old, who were undergoing their pre-school medical examinations. In 151 children (7.4%), the threshold for hearing was above 20 dB for at least one frequency. Of these, 82 children (4% of the overall sample) had a hearing impairment defined as a difference of > or = 10 dB between at least one frequency (3, 4 or 6 kHz) and the mean value from 1+2 kHz. This was evaluated as a sensorineural hearing loss. Unilateral losses (lateral difference > or = 10 dB) were more common than bilateral losses (2.5% vs 1.6% of the overall sample). These unilateral hearing losses in the high-frequency range are essentially regarded as the result of playing with impulse-noise producing toys, such as toy guns with caps.
采用改良的听力筛查方法，对2032名6至7岁正在接受学前体检的儿童进行了0.5至6千赫频率范围的听力图检测。在151名儿童（7.4%）中，至少有一个频率的听力阈值高于20分贝。其中，82名儿童（占总样本的4%）存在听力障碍，定义为至少一个频率（3、4或6千赫）与1 + 2千赫的平均值之间的差异≥10分贝。这被评估为感音神经性听力损失。单侧听力损失（左右耳差异≥10分贝）比双侧听力损失更为常见（分别占总样本的2.5%和1.6%）。高频范围内的这些单侧听力损失基本上被认为是玩能产生脉冲噪声的玩具，如带帽玩具枪所致。
