幼儿轻度听损要不要配助听器？什么时候戴助听器比较合适？
从理论上讲应该验配。但是这对验配师有极高的要求，好像为一岁的小朋友配一副50度的近视眼镜：
1. 孩子是不是确诊为不可逆（不能治愈）的听力损失；
2. 有没有经过“综合诊断，多次复查”的确诊，还是仅仅一次简单的检查？
3. 能不能确保助听器的放大不损害孩子现有的听力？
因此，对于幼儿的轻度听力损失（比如平均听力40 dB），如果不能回答以上问题，情愿不配助听器而暂时采取观察的方法。等确诊以后再定。
比利时列日大学科学家罗纳德·波尤拍摄的人类耳蜗的华丽照片。这张照片被称为“声音的螺旋”，Pouyo写道：
这是一张耳蜗的图片，我用免疫组织化学方法对其进行了解剖和标记。之后耳蜗被澄清，用光片显微镜拍摄照片。内耳保护耳蜗，耳蜗是一个螺旋形的细胞，其作用是通过毛细胞捕捉空气振动（用红色标记）。这些独特的细胞将声音转换成电信号，然后通过神经纤维（绿色标签）传递给大脑。所有其他的细胞核都用蓝色标记。我认为自己很幸运能够在这样一个美丽而复杂的结构上工作，而这个结构还没有被完全理解。”
Gorgeous photo of a human cochlea, taken by a scientist, Ronald Pouyo, from the University of Liege, Belgium. The picture is called "Spiral of Sound." Pouyo wrote:
"This is a picture of a cochlea I dissected and labelled by immunohistochemistry. After that the cochlea was clarified and the picture was taken with a Light-sheet microscope. The inner ear shelters the cochlea, a spiral of cells whose role is to capture the air vibration through the hair cells (labelled in red). These unique cells convert sounds into electrical signals that are relayed to the brain via the neuronal fibers (labelled in green). All the other cell nuclei are labelled in blue. I consider myself lucky to be able to work on such a beautiful and complex structure, which has yet to be fully understood."
