The paper concerns one of new ways to improve the interface of a modern aircraft cockpit, namely a 3D-audio technology application. The 3D-audio is a technology that reproduces the spatially directed sound via earphones or loudspeakers. Spatial audio-cues together with information about a danger, which also point out the direction it emerges from, can reduce the time of response to the event, thereby increasing the situation safety of flight.The offered paper describes the approved methods to implement the 3D-audio technology. It also presents results of experiments on evaluating the accuracy characteristics of localized directions towards the sound source for some types of audio signals.A scientific novelty is to achieve the true-to-life quantitative characteristics of 3D-audio technology to be appropriate for the modern aircraft cockpit interface design.
