Virtual auditory environments (VAEs) are created by filtering digital sounds through HRTFs (Head-Related Transfer Functions) such that they convey a spatial location to the listener. The most accurate HRTFs are obtained by direct individual acoustic measurement, however this is a costly and time-consuming process. Subjective selection arises as a low cost alternative to obtaining customized HRTFs, however, this manner of selection is perceptual in nature, and a user`s choices may change over time. The validity of using subjective selection for HRTF customization relies on the consistency of the HRTFs selected by listeners. The present work assesses how listener`s subjectively selected HRTFs may change over time. The results suggested that listeners are able to select adequate HRTFs in one session, without the need for additional sessions.
