摘 要：目的比较移频助听器与非移频助听器在重度以上听力障碍患者听力康复中对声音的感知、辨别能力和语训效果.方法以助听听阈、清晰度指数(AI)、Ling's 6音的感知率和听辨率测试以及听音辨图测试得分为指标比较移频和非移频助听器在声音的感知、辨别、识别方面的差异表现.结果移频助听听阈较非移频助听听阈明显改善,在2 000 Hz以后的高频区改善尤为明显(t＝2.45～47.46,P＜0.01).移频助听器对清晰度指数较非移频助听器有非常显著的提高(t＝16.89,P＜0.01).非移频助听状态下元音的感知率和听辨率较裸耳有显著提高(X2＝7.5～78.19,P＜0.01),但对辅音的感知率和辨别率无明显提高.但移频助听状态下的辅音、元音/i/的感知率和听辨正确率都明显高于非移频助听状态.移频助听的听音辨图测试得分较非移频助听时有明显的改善(t＝16.89,P＜0.01).结论移频助听器比非移频助听器在重度以上听力障碍患者的听力康复中,对声音感知、辨别、识别能力三个方面具有更好的助听效果.
