Speech discrimination performance utilizing CID W-22 word lists and patient preferences for hearing aids were investigated. Preference judgments were made using the magnitude estimation procedure. 10 experienced hearing aid users served as subjects. Results revealed that speech discrimination using CID W-22 words was unable to differentiate among hearing aids which possessed similar electroacoustic characteristics. In contrast, the magnitude estimation quality judgment procedure was quite effective and reliable at differentiating among the hearing aids. Further, the magnitude estimation quality judgment procedure is able to provide numerous preference judgments about each hearing aid in a relatively short time. In addition, the magnitude estimation procedure has a major advantage over the paired-comparison quality judgment procedure in that the patient is able to actually wear the hearing aid during the magnitude estimation procedure.
研究了使用CID W - 22单词列表的言语辨别性能以及患者对助听器的偏好。使用量值估计程序进行偏好判断。10名有经验的助听器使用者作为受试者。结果显示，使用CID W - 22单词的言语辨别无法区分具有相似电声特性的助听器。相比之下，量值估计质量判断程序在区分助听器方面相当有效且可靠。此外，量值估计质量判断程序能够在相对较短的时间内对每个助听器提供大量的偏好判断。另外，量值估计程序相对于配对比较质量判断程序具有一个主要优势，即患者能够在量值估计程序期间实际佩戴助听器。
