论文摘要
在本研究中，使用模拟听力损失（HL）在实验室和远程环境中进行语音清晰度（SI）实验，以阐明外围功能障碍的影响。处理了嘈杂的语音，以使用Wadai听力障碍模拟器（Whis）模拟70岁和80岁儿童的平均HL。这些声音被视为正常听力（NH）听众，他们的认知功能可以假定为正常。结果表明，在远程实验中的差异比实验室的差异更大。但是，远程结果可以与实验室网页上准备的音调PIP测试的结果相均衡，主要是通过数据筛选。此外，一种新提出的客观可理解度措施（OIM）称为伽马希普（Gammachirp）信封相似性指数（GESI），在实验室和远程实验中的心理测量功能相当很好。 GESI有可能通过正确设置HL参数来解释HI听众的SI。
In the present study, speech intelligibility (SI) experiments were performed using simulated hearing loss (HL) sounds in laboratory and remote environments to clarify the effects of peripheral dysfunction. Noisy speech sounds were processed to simulate the average HL of 70- and 80-year-olds using Wadai Hearing Impairment Simulator (WHIS). These sounds were presented to normal hearing (NH) listeners whose cognitive function could be assumed to be normal. The results showed that the divergence was larger in the remote experiments than in the laboratory ones. However, the remote results could be equalized to the laboratory ones, mostly through data screening using the results of tone pip tests prepared on the experimental web page. In addition, a newly proposed objective intelligibility measure (OIM) called the Gammachirp Envelope Similarity Index (GESI) explained the psychometric functions in the laboratory and remote experiments fairly well. GESI has the potential to explain the SI of HI listeners by properly setting HL parameters.
