There is a dearth of information on the effects of bone conductive devices on temporal processing in individuals with single-sided deafness (SSD). This study investigates the effect of an adhesive bone conductive device on temporal processing in adults with SSD.
A prospective cohort study of temporal processing in adults with SSD was undertaken. Outcome measures were the pitch pattern test (PPT) and the duration pattern test (DPT) scores, sound field pure tone audiometric (PTA) averaged hearing thresholds, and word recognition scores (WRS). These were measured under 3 conditions: unaided in quiet, unaided in noise, and aided in noise. Eight SSD novice hearing amplification users were recruited.
The adhesive bone conduction device (BCD) resulted in a statistically-significant improvement (Wilcoxon signed ranks test, = .018) in median [interquartile range (IQR)] PPT score, 65% (IQR = 35.5), and DPT score, 38% (IQR = 42.5) in noise.
Adults with SSD demonstrated improved temporal processing scores with masking of the normal-hearing ear when using an adhesive BCD placed behind the deafened ear.
关于骨传导装置对单侧耳聋（SSD）个体时间处理能力影响的信息匮乏。本研究调查了一种粘性骨传导装置对成年SSD患者时间处理能力的影响。
对成年SSD患者的时间处理能力进行了一项前瞻性队列研究。结果测量指标为音调模式测试（PPT）和时长模式测试（DPT）分数、声场纯音听力测定（PTA）平均听阈以及单词识别分数（WRS）。这些指标在三种条件下进行测量：安静环境下未佩戴辅助设备、噪声环境下未佩戴辅助设备以及噪声环境下佩戴辅助设备。招募了8名SSD听力放大新手用户。
粘性骨传导装置（BCD）使噪声环境下的PPT中位数[四分位间距（IQR）]分数显著提高（Wilcoxon符号秩检验，P = 0.018），提高了65%（IQR = 35.5），DPT分数提高了38%（IQR = 42.5）。
成年SSD患者在患耳后方佩戴粘性BCD并对正常听力耳进行掩蔽时，时间处理分数有所提高。
