本文总结了在我省区用声阻抗仪之声反射对正常103人,206耳之纯音反射阈(PTAR)和白噪声反射阈(WNAR)等数值进行测定,并用之预估200耳客观听敏度。结果:白噪声数值较其他地区统计数字偏高。预估听敏度与电测听实测数符合率约为68.5%;其余31.5%误差一个等级。对此进行了分析讨论,供我省高原地区开展此项工作参考。
This paper summarizes the use of acoustic impedance acoustic reflectance in our province on normal 103 people, 206 ears pure tone reflection threshold (PTAR) and white noise reflection threshold (WNAR) and other values were measured and used to predict 200 ears objective listening degree. Results: The white noise figures are higher than those in other regions. The estimated hearing sensitivity and electrical measured measured coincidence rate of about 68.5%; the remaining 31.5% error of a grade. This analysis was discussed for the province of Plateau to carry out this work reference.
