目的探究言语刺激强度对健听者听配能的影响。方法选取38例健听成人,采用语速x刺激强度的言语理解测试范式,将瞳孔扩张听配能测量和听觉任务完成准确度及反应速度相结合,观察阈上范围内20 dB SPL的强度变化对听配能和任务表现的影响。...目的探究言语刺激强度对健听者听配能的影响。方法选取38例健听成人,采用语速x刺激强度的言语理解测试范式,将瞳孔扩张听配能测量和听觉任务完成准确度及反应速度相结合,观察阈上范围内20 dB SPL的强度变化对听配能和任务表现的影响。结果语速对平均瞳孔扩张有显著影响(P<0.001,η_(p)^(2)=0.618),但刺激强度对平均瞳孔扩张无显著影响(P=0.213,η_(p)^(2)=0.040)。增加言语刺激强度能够显著提升任务反应速度(P=0.043,η_(p)^(2)=0.099),在正常语速下,还能够显著提升言语理解准确度(P<0.001,η_(p)^(2)=0.374)。结论健听人群听觉舒适阈范围内将言语声刺激强度增加20 dB SPL能够提高聆听效率,但该效应可能并不是通过改变可听度或唤醒度,从而影响听配能结果,可能是改变听觉处理速度。展开更多

The problem is even magnified more with the lack of transparency by Cloud Service Providers (CSPs). Auditing and compliance enforcement introduce different set of challenges in cloud computing that are not yet resolved. In this paper, a conducted questionnaire showed that the data owners have real concerns about not just the secrecy and integrity of their data in cloud environment, but also for spatial, temporal, and legal issues related to their data especially for sensitive or personal data. The questionnaire results show the importance for the data owners to address mainly three major issues: Their ability to continue the work, the secrecy and integrity of their data, and the spatial, legal, temporal constraints related to their data. Although a good volume of work was dedicated for auditing in the literature, only little work was dedicated to the fulfillment of the contractual obligations of the CSPs. The paper contributes to knowledge by proposing an extension to the auditing models to include the fulfillment of contractual obligations aspects beside the important aspects of secrecy and integrity of client’s data.展开更多
目的探究可训练助听器增益训练功能开启的时间对可听度及噪声下言语理解度的影响。方法采用双盲试验将36名助听器初戴者随机分为两组，实验组的增益训练功能在助听器验配当天开启，而对照组的增益训练功能在验配1个月之后开启。经过三...目的探究可训练助听器增益训练功能开启的时间对可听度及噪声下言语理解度的影响。方法采用双盲试验将36名助听器初戴者随机分为两组，实验组的增益训练功能在助听器验配当天开启，而对照组的增益训练功能在验配1个月之后开启。经过三个阶段为期10周的增益调节和听觉适应后，采用言语清晰度指数（speech intelligibility index，SII）、噪声下言语测试（Hearing In Noise Test，HINT）、助听响度问卷调查表（Profile of Aided Loudness，PAL）和助听器效果国际性调查问卷（International Outcome Inventory for HearingAids，IOI—HA）对助听器效果进行评估。结果两组在验配后第8周的轻声可听度有明显差异，但主观言语测试结果无显著差异；61％的受试者更倾向于使用增益训练后得到的优化增益，并且希望继续使用增益训练功能。结论提前开启增益训练功能虽然对最终获得的优选增益有影响，但对助听后言语理解度没有影响。展开更多
