标题： Binaural Unmasking in Practical Use: Perceived Level of Phase-inverted Speech in Environmental Noise

摘要： 我们旨在开发一种技术，使从耳机和耳塞发出的声音更容易听到，而不会增加声压或消除环境噪声。 为此，我们专注于通过单侧相位反转来利用双耳掩蔽现象。 具体而言，我们进行实验以评估该现象引起的可听性改善，在接近实际场景的条件下进行评估。 我们使用不同说话者的语音声音，包括女性的声音，以及日常生活中可能遇到的噪音（城市环境声音、欢呼声）来验证在接近实际情况下双耳掩蔽的效果。 使用日语进行的实验结果表明，(i) 在嘈杂环境中，单侧相位反转使语音听起来大约响6分贝，(ii) 对本研究中针对的所有说话者和噪音都获得了某种效果（可听性提高5分贝或更多）。 这些发现证明了双耳掩蔽在实际场景中由于双耳相位差异的有效性。 显示英文摘要

摘要： We aim to develop a technology that makes the sound from earphones and headphones easier to hear without increasing the sound pressure or eliminating ambient noise. To this end, we focus on harnessing the phenomenon of binaural unmasking through phase reversal in one ear. Specifically, we conduct experiments to evaluate the improvement of audibility caused by the phenomenon, using conditions that approximate practical scenarios. We use speech sounds by various speakers, including women, and noises that can be encountered in daily life (urban environmental sounds, cheers) to verify the effects of binaural unmasking under conditions close to practical situations. The results of experiments using the Japanese language showed that (i) speech in a noisy environment is perceived to be up to about 6 dB louder with phase reversal in one ear, and (ii) a certain effect (improvement of audibility by 5 dB or more) is obtained for all speakers and noises targeted in this study. These findings demonstrate the effectiveness of binaural unmasking attributed to interaural phase differences in practical scenarios.
