耳内植入技术允许在耳朵（双峰）和同一耳朵（电声刺激或EAS）内组合声刺激和电刺激。双峰和EAS听力之间用于整合语音声学的机制可能不同，并且听力损失的配置可能是整合的重要因素。因此，区分听力损失的不同配置对言语感知中的双峰或EAS益处的影响（声电组合刺激与单独更好的刺激的性能差异）是重要的。使用声学模拟，我们确定了如何辅音识别的影响，不同配置的听力损失双峰和EAS听力。采用混合设计，其中包括一个受试者间变量（模拟双峰组与模拟EAS组）和一个受试者内变量（单独声刺激、单独电刺激、声电联合刺激）。招募了20名听力正常的成年受试者（每组10名）。在安静的条件下，单侧或双侧测量辅音感知。对于声学刺激，通过带通滤波辅音创建四种不同的听力损失模拟，其中固定的下限截止频率为100 Hz，四个上限截止频率分别为250、500、750和1000 Hz。对于电刺激，使用8通道噪声声码器通过使用固定的输入（200-7000 Hz）和输出（1000-7000 Hz）频率范围来产生典型的频谱失配。比较两组受试者在模拟听力损失条件下对辅音识别的影响。无论听力损失和听力技术的配置如何，均发生了显著的双峰和EAS获益（双峰vs EAS）。位置信息在EAS听力中的传递比在双峰听力中的传递更好。这些结果表明，听力损失的配置是不是一个显着的因素整合之间的声学和电刺激的辅音信息。研究结果还表明，用于整合辅音信息的机制可能是类似的双峰和EAS听力。
Cochlear implant technology allows for acoustic and electric stimulation to be combined across ears (bimodal) and within the same ear (electric acoustic stimulation, or EAS). Mechanisms used to integrate speech acoustics may be different between the bimodal and EAS hearing, and the configurations of hearing loss might be an important factor for the integration. Thus, differentiating the effects of different configurations of hearing loss on bimodal or EAS benefit in speech perception (differences in performance with combined acoustic and electric stimulation from a better stimulation alone) is important. Using acoustic simulation, we determined how consonant recognition was affected by different configurations of hearing loss in bimodal and EAS hearing. A mixed design was used with one between-subject variable (simulated bimodal group vs simulated EAS group) and one within-subject variable (acoustic stimulation alone, electric stimulation alone, combined acoustic and electric stimulation). Twenty adult subjects (ten for each group) with normal hearing were recruited. Consonant perception was unilaterally or bilaterally measured in quiet. For the acoustic stimulation, four different simulations of hearing loss were created by band-pass filtering consonants with a fixed lower cutoff frequency of 100 Hz and each of the four upper cutoff frequencies of 250, 500, 750, and 1000 Hz. For the electric stimulation, an 8-channel noise vocoder was used to generate a typical spectral mismatch by using fixed input (200-7000 Hz) and output (1000-7000 Hz) frequency ranges. The effects of simulated hearing loss on consonant recognition were compared between the two groups. Significant bimodal and EAS benefit occurred regardless of the configurations of hearing loss and hearing technology (bimodal vs EAS). Place information was better transmitted in EAS hearing than in bimodal hearing. These results suggest that configurations of hearing loss are not a significant factor for integrating consonant information between acoustic and electric stimulation. The results also suggest that mechanisms used to integrate consonant information may be similar between bimodal and EAS hearing.
