1 问:如何判断自己是否有耳聋? 答:医疗康复机构所进行的纯音测听结果简称听力图,是判定耳聋的依据。将测听图上500、1000和2000HZ的3个点的听力值相加后再除以3,它的得数若:小于26dB(dB即分贝)表示听力正常,介于26～40之间为轻度耳聋,介于41～55之间为中度聋,介于56～70之间为中重度聋,介于71～90之间为重度聋,大于90dB为极度耳聋。 在日常生活中,如果耳语声不能闻及则表示听力损失超过了30dB; 1 Q: How to determine whether they have deafness? A: Medical rehabilitation agencies conducted pure tone audiometry referred to as audiogram, is to determine the basis for deafness. The audiogram at 500,1000 and 2000HZ 3 points after adding the hearing value divided by 3, the number of its if: less than 26dB (dB decibels) that hearing normal, between 26 to 40 Mild deafness, ranged from 41 to 55 for moderate deafness, between 56 to 70 for moderate to severe deafness, between 71 to 90 for severe deafness, greater than 90dB for extreme deafness. In everyday life, hearing loss can exceed 30dB if the whisper can not be heard;
