PURPOSE
The objective of the study was to investigate the influence of noise (energetic) and speech (energetic plus informational) maskers on the head shadow (HS), squelch (SQ), and binaural summation (SU) effect in bilateral and bimodal cochlear implant (CI) users.
METHOD
Speech recognition was measured in the presence of either a competing talker or modulated speech-shaped noise in 10 bimodal and 10 bilateral adult CI users. HS, SQ, and SU effects were calculated. The interfering signals were manipulated with respect to F0 to consider the influence of different speaker voices.
RESULTS
The effects HS, SQ, and SU differed depending on the type of masker. A detailed analysis of errors was used to dissociate energetic and informational masking effects. The analysis showed a release from energetic than from informational masking.
CONCLUSION
Noise interferers are not sufficient to reflect difficulties experienced with speech understanding in noise for bilateral and bimodal CI users.
目的
本研究的目的是调查噪声（能量型）和言语（能量型加信息型）掩蔽器对双侧和双模式人工耳蜗（CI）使用者的头影（HS）、静噪（SQ）和双耳总和（SU）效应的影响。
方法
在10名双模式和10名双侧成年CI使用者中，在存在竞争谈话者或调制言语形状噪声的情况下测量言语识别。计算HS、SQ和SU效应。针对基频（F0）对干扰信号进行操作，以考虑不同说话者声音的影响。
结果
HS、SQ和SU效应因掩蔽器类型而异。对错误进行详细分析以区分能量掩蔽效应和信息掩蔽效应。分析表明，从能量掩蔽中解脱出来的程度大于从信息掩蔽中解脱出来的程度。
结论
对于双侧和双模式CI使用者，噪声干扰不足以反映在噪声中言语理解所遇到的困难。
