我们在50名SNHL听众的受试者内器械内交叉设计中研究了线性、慢作用AVC助听器和快作用WDRC助听器的候选人资格。测量尺寸包括HTL。ULL、频谱-时间和掩蔽异常、认知能力、自我报告和听觉生态学的声学测量线性拟合的更好表现与更平坦的听力图、更宽的动态范围、低频和高频之间的动态范围差异较小以及更受限制的听觉生活方式相关。所有非线性拟合的更好性能与更倾斜的听力图、更受限的动态范围、低频和高频之间的动态范围差异更大以及更多样化的听觉生活方式相关。WDRC和AVC拟合之间的差异性能与听觉生态的变化模式相关（快速与缓慢变化）和认知（高与低）容量两个通道中的WDRC之间的差异性能，以及低频中的WDRC和高频通道中的AVC的混合与耳蜗功能的心理声学测试相关（分别对频谱和时间拖尾的高敏感性，以及对掩蔽的向上扩展的高敏感性）。候选模式包括认知能力和听觉生态学领域中听觉功能以外的测量。
We studied candidature for linear, slow-acting AVC hearing aids, and fast-acting WDRC hearing aids in a within-subject within-device crossover design of 50 listeners with SNHL. Candidature dimensions include HTLs. ULLs, spectro-temporal and masking abnormalities, cognitive capacity, and self-reports and acoustic measures of auditory ecology Better performance with linear fittings is associated with flatter audiograms, wider dynamic range, and smaller differences in dynamic range between low and high frequencies, and also with more restricted auditory lifestyles. Better performance with all nonlinear fittings is associated with more sloping audiograms, more restricted dynamic ranges, greater differences in dynamic range between low and high frequencies, and more varied auditory lifestyles. Differential performance between WDRC and AVC Fittings is associated with patterns of variation in auditory ecology (rapid versus slow changes) and cognitive (high versus low) capacity Differential performance between WDRC in two channels, and a hybrid with WDRC in a low-frequency and AVC in a high-frequency channel is associated with psychoacoustic tests of cochlear function (high susceptibility to spectral and temporal smearing, and high susceptibility to upward spread of masking respectively). patterns of candidature include measures beyond auditory function in the domains of cognitive capacity and auditory ecology.
