Four experienced hearing aid users were evaluated using a frequency transposition (TranSonic) hearing system. Following a trial period, the Abbreviated Profile of Hearing Aid Performance (APHAB) and a variety of speech audiometric measures were used to compare the frequency transposition fitting with each subject's conventional hearing aids. A single-subject study design with a series of repeated measures permitted statistical analysis of differences in performance with the various amplification strategies. Two of the four subjects demonstrated statistically significant benefit with the frequency transposition device. Results show the efficacy of frequency transposition in improving speech understanding and quality of life in some individuals with severe-to-profound hearing loss. Overall, results suggest the need for evaluating the benefit of frequency transposition on an individual basis.
使用频率转换（TranSonic）听力系统对四名有经验的助听器使用者进行了评估。在一个试验期之后，使用助听器性能简表（APHAB）和各种言语听力测量方法，将频率转换适配与每个受试者的传统助听器进行比较。采用单受试者研究设计并进行一系列重复测量，以便对不同放大策略的性能差异进行统计分析。四名受试者中有两名在使用频率转换设备后显示出统计学上的显著益处。结果表明，频率转换对于改善一些重度至极重度听力损失患者的言语理解和生活质量是有效的。总体而言，结果表明需要基于个体情况评估频率转换的益处。
