摘要

目的评价听障儿童佩戴助听设备并耦连无线调频系统(frenquency modulation system,FM)后的助听效果。方法采用儿童无线调频系统辅听效果评估问卷(FM listening evaluation for children)对使用人工耳蜗和/或助听器的27例3.485.5岁学龄前重度-极重度感音神经性聋儿童应用FM的助听效果进行评估。分别评估FM+麦克风(microphone,M)(FM+M)和麦克风(M)模式下其在安静环境、噪声环境、回避视觉及远距离4种聆听环境中的聆听效果(计算百分率),分数越高表明助听效果越好。结果 M模式下总分为67.55%,安静环境得分85.33%,噪声环境60.54%,回避视觉69.58%,远距离69.58%,不同聆听环境下得分差异有统计学意义(F=49.53,P<0.05),其中安静环境下聆听效果显著优于噪声、回避视觉及远距离环境;FM+M模式下总分为84.35%,安静环境得分94.89%,噪声环境81.35%,回避视觉83.56%,远距离83.29%,不同聆听环境下得分差异有统计学意义(F=24.80,P<0.05),其中,安静环境下聆听效果显著优于噪声、回避视觉及远距离环境。FM+M模式下聆听效果显著优于M模式(P<0.05)。结论 FM系统可提高佩戴助听设备的听障儿童在复杂环境下的聆听效果。
