The current study was focused on establishing the type of the envelope an auditory warning signal should have in order to minimize its distracting effect on the attention. Listener's ability to localize square wave and ramp spatial sounds was investigated. Their performance was evaluated using SMI EyeLink Gaze Tracking system. Both the auditory stimuli could be localized equally well. The reaction time was shorter for the square wave, but not significantly different from the ramp condition. The ramp stimulus, however, was reported by the participants to be more acceptable, were it to be used. The approach of using spatial sounds with a gradual onset might be a reasonable option to be considered when selecting the most effective shape for a warning audio signal.
