This study expands upon our earlier work by comparing initial PB scores and audiometric thresholds with results obtained 4-17 years later for subjects with bilateral sensorineural hearing losses who were monaurally aided (n = 48), binaurally aided (n = 19), or unaided (n = 19). Thresholds decreased slightly for all groups, but aided and unaided ears did not differ significantly in this respect, revealing no acoustic trauma effect due to hearing aid use. PB scores decreased significantly only for the unaided ear of the monaurally aided subjects, but not for their aided ear, or for the binaurally aided or unaided groups. These findings suggest an auditory deprivation effect for the unaided ear of those wearing a monaural hearing aid. Changes in PB scores were not correlated with duration between the two test dates. Changes in PB scores were correlated with degree of hearing loss only for the unaided group.
本研究在我们早期工作的基础上进行了拓展，比较了双侧感音神经性听力损失且单侧佩戴助听器（n = 48）、双侧佩戴助听器（n = 19）或未佩戴助听器（n = 19）的受试者的初始PB分数和听力阈值与4至17年后获得的结果。所有组的阈值均略有下降，但在这方面，佩戴助听器和未佩戴助听器的耳朵之间没有显著差异，表明使用助听器没有声学创伤效应。仅单侧佩戴助听器的受试者的未佩戴助听器的耳朵的PB分数显著下降，但其佩戴助听器的耳朵以及双侧佩戴助听器或未佩戴助听器的组的PB分数并未下降。这些发现表明，佩戴单侧助听器的人的未佩戴助听器的耳朵存在听觉剥夺效应。PB分数的变化与两次测试日期之间的持续时间无关。PB分数的变化仅与未佩戴助听器组的听力损失程度相关。
