This study aims at developing a hearing aid system which utilizes binaural hearing mechanism. This leads to realize a good performance of hearing through the good spacial selectivity for signal sound achieved by binaural listening with the two ears. Benefits were not expected for binaural listening when the difference of hearing levels between two ears is large. However, it could be expected by compensating the recruitment in loudness correctly for both ears. In 1994, thus, examinations to extend our algorithm to compensate the recruitment to two channels was conducted. Moreover, basic research to examine binaural hearing acuity psychoacoustically was also conducted. In 1995, a real time system which realized the extended algorithm was buit and hearing experiments were conducted. As results of the experiments, it was shows that speech intelligibility was significantly improved by the binaural listening. Moreover, it is found that binaural listening with the algorithm enabled subjects who exhibit good MLD a good performance in the presence of noise and a good sound localization. From the above results, we could conclude that good performance in both speech intelligibility and sound localization could be expected if the recruitment in loudness is correctly compensated for for both ears.

这项研究旨在开发使用双耳听力机制的助听器系统。这导致通过双耳的双耳聆听来实现良好的空间选择性来实现听力的良好表现。当两只耳朵之间的听力水平差异很大时，双耳聆听的益处并不是期望的。但是，可以通过正确补偿两只耳朵的响度招募，可以预期。因此，在1994年进行了扩展我们的算法以补偿招募到两个渠道的检查。此外，还进行了基础研究以进行心理敏锐的敏锐度。 1995年，实时系统意识到扩展算法是构建的，并进行了听力实验。作为实验的结果，这表明双耳聆听可以显着提高语音清晰度。此外，发现具有算法的双耳聆听功能，他们在噪音和良好的声音本地化的情况下表现出良好的MLD表现出色。从上述结果中，我们可以得出结论，如果对这两只耳朵都正确补偿了响度的招募，则可以预期语音清晰度和声音定位的良好表现。
