如何选择我的助听器

如何选择我的助听器如何选择我的助听器
助听器之所以对8000Hz以上的高频信号反应差有两个主要原因:
其一,助听器不是普通的音响设备。因为体积小,现代声学技术还难以在这样微小的空间内设计出宽范围的频响性能。即使能做到这一点,造价也,恐怕绝大多数人不会买得起;
其二,语言沟通是人类听觉的主要用途与主要特征。语言声相对集中于500–4000Hz频段。如果在这一频段放大性能好,有助于提高语言沟通的需要,还有助于消除非语言噪声,特别是低频噪声。
对助听器效果影响大的是听力残疾人自己的听觉分辨能力。多数听力残疾人都有不同程度的听觉分辨能力的损失。损失的不多,助听器可以补偿。若损失过于严重(这种情况多见于听觉中枢的障碍),助听器也就无能为力了。助听器还不能取代大脑皮层的作用。
跟眼镜有度数一样,助听器也是要根据每个人情况的不同来调整的,而且患者戴上助听器后,需要经过一段时间的适应性训练,才能对声音产生认识。适应训练的成功与否,是决定助听器验配周期长短的重要环节。一般来讲,经过2~3个月的严格训练,患者适应佩戴助听器、熟悉不同频率的纯音和啭音、能分辨声音的有无并做出行为反应,才能对患者助听效果进行评估。患者选配助听器的终目的是能够听清语言,进行正常的社会交往。因此,用言语测听对助听效果进行功能评估十分,应伴随患者逐渐掌握的词汇或语句跟踪进行。定期评估患者配戴助听器后接受语言信息的能力,较全面地评价助听效果。如何选择我的助听器
