听力测定

Methods:BAEP and audiogram were tested in 225 patients with ear injury and 60 normal subjects.

对 2 2 5例耳外伤者及 6 0例正常人进行BAEP及纯音听力测定。

Methods 134 patients with type 2 diabetes were determined by pure tone audiometry, auditory brainstem responseand distortion product otoacoustic emissions. The risk factors of hearing loss were analyzed by logistic regression analysis. Results 41.8% patients had hearing loss.

测定134例2型糖尿病患者的纯音测听、脑干听觉诱发电位和畸变产物诱发电位结果，回顾性分析听力正常组和异常组的临床资料，并应用多因素logistic回归分析探讨影响听力的危险因素。

The second part is"the evaluation of brainstem auditory evoked potentials on 303 cases of deaf-mutism and the cause analysis of acquired deaf-mutism". 37. 3%(113 cases, 171 ears ) of all the cases were found to have residual hearing of various levels.

其二是"对303例聋哑患者的脑干听觉诱发电位测定和后天性聋哑病因分析"，发现在303例聋哑患者中，37.3%（113例，171耳）尚有不同程度的残余听力。

Determining the presence of hearing loss can be measured ABR hearing.

确定有无听觉损害可进行脑干诱发电位听力测定。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
