Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we compared two audio output devices for augmented audio reality applications. One is the bone-conduction headphones, and the other is the binaural microphone/earphone combo. Both devices can be "hear-through" sound playback. We compared the speech intelligibility of speech when competing babble noise is simultaneously given from the surrounding environment. First, the mean value of speech intelligibility was equal to the bone-conduction headphones and the binaural combo, but the confidence interval of intelligibility was different. Next, we employed a compensation filter to account for the ear canal transfer function deviation, the resultant speech intelligibility was found to be higher at least 10% than the natural hearing. In any case, both of these are found to be acceptable as audio output devices for augmented audio reality applications since both are able to deliver speech at high intelligibility even when significant amount of competing noise is present.
