Abstract

There have been several isolated reports of hearing loss due to noise levels from toys. Guidelines for noise production by toys is regulated by the Voluntary Product Standards PS 72-76: Toy Safety Act of 1969. To determine the current risk of noise induced hearing loss from toys currently on the market, 25 toys were purchased at a national toy store chain and sound levels were measured at distances approximating ear level (2.5 cm) and a child's arm length (25 cm) from the surface of the toy. Testing revealed peak sound levels ranging from 81 to 126 dBA at 2.5 cm and 80 to 115 dBA at 25 cm from the surface of the toy.

摘要

已有多份关于玩具噪音导致听力损失的孤立报告。玩具噪音产生的指导方针由1969年的自愿产品标准PS 72 - 76：《玩具安全法案》规定。为了确定当前市场上玩具导致噪音性听力损失的风险，在一家全国性玩具连锁商店购买了25件玩具，并在距离玩具表面近似于耳部高度（2.5厘米）和儿童手臂长度（25厘米）处测量了声级。测试显示，在距离玩具表面2.5厘米处，峰值声级范围为81至126分贝A，在25厘米处为80至115分贝A。
