| 摘 要： | 作者在高海拔地区（２４５０米、大气压７５．６６ｋＰａ、氧分压１５．８９ｋＰａ）对藏及土族老年人１１３例（２２３耳）进行了纯音听力测试和头发中三种微量元素锌（Ｚｎ）、铬（Ｃｒ）、铜（Ｃｕ）的测定。结果：各年龄组纯音听力中骨传导听阈较气传导听阈低１０ｄＢ以上，以７０～７９岁组明显（ｐ＜０．０１），年龄与语言频率听阈呈正相关（ｎ＝１１３、ｒ＝０．４８２６、ｐ＜０．０１）；锌与听阈呈负相关（ｎ＝１１３、ｒ＝－０．２９９４、ｐ＜０．０１）；铬与听阈呈正相关（ｎ＝１１３、ｒ＝０．３３４３、ｐ＜０．０１）；铜与听阈无相关性（ｎ＝１１３、ｒ＝－０．０６２、ｐ＞０．５０）。

| Abstract: | The paper reportcd the relations between pure tone hearing and trace element (Zn Cr Cu) of the human hair in the Tibetan and the Tu nationlity elderly at high altitude (2450metres above sea level.Atmospheric pressure 75. 66 kpa.Oxygen pressure 15. 89 kpa).Our results indicated that: 1 . In every year groups, The pure tone hearing (dB HL)bone conduction was about 10 dB HL lower than the air conduction (p<0.01) .2. The ages and speech frequency hearing threshold had positive correlation (N=113 R=0.4826 F<0.01). 3. Zine and hearinig threshold had negative correlation (N=113 R=-0.2994 P<0.01). 4. Cnromiun and hearing threshold had positive correlation (N=113 R=0.3343 p<0.01). 5. Copper and hearing threshold had Ne correlation (N=113 R=-0.062 p>0.50). |
