In this study, speech perception with commercially available linear and single-channel input- and output-dependent compression aids was investigated. Although compression has been introduced as a method of limiting the maximum output, theoretically expectations have been raised that a gain in speech intelligibility could also be obtained by a better use of the reduced dynamic range of the patient. It turned out that there was no significant difference in speech reception thresholds obtained both in quiet and in noise between the aids used for a group of 12 hearing-impaired hearing-aid users as a whole, or for different subgroups thereof.
在本研究中，对市售的线性和单通道输入及输出相关压缩助听设备的言语感知进行了调查。尽管压缩技术作为一种限制最大输出的方法已被引入，但理论上人们期望通过更好地利用患者减小的动态范围也能提高言语清晰度。结果发现，对于一组12名听力受损的助听器使用者整体或其不同亚组所使用的助听设备，在安静环境和噪声环境下获得的言语接受阈值并无显著差异。
