The purpose of this study is to build a monaural auditorydisplay to convey four pieces of directional information(upward, downward, rightward, and leftward) to userseffectively and intuitively without the need for wearingheadphones or preparing more than one speaker. We preparedfive types of monaural auditory displays consisting of trianglewave sounds and conducted an experiment to investigatewhich kinds of displays succeeded in conveying the fourpieces of information to participants. As a result, we couldconfirm that one of the prepared monaural auditory displays,designed as a “progress bar” on the basis of the mental-number line and spatial-number association of the responsecode effect, succeeded in conveying the four pieces ofinformation more effectively compared with the othercandidate sets (its average correct rates were about 0.88). Thisresult thus strongly shows that this monaural auditory displaywas quite useful for conveying primitive spatial informationto users
