It is a well-known fact that both bone-conducted and air-conducted sound contribute to the perception of one's own voice. As early as 1949 Bekesy described experiments which were aimed at estimating the ratio of the two components' contributions. In this article investigations are described which quantitatively analyse the influences of air conduction, bone conduction and of the reflections on the sound of a person's own voice. Different methods for measuring the components were applied. Concerning the air conduction, direct measurements of sound propagation from the mouth to the ears around the head were performed. As the bone conduction cannot be measured directly, psychoacoustic methods based on masking effects were used to evaluate this component. The reflections in a room can be modelled by methods that apply geometric acoustics. The results of the measurements are compared to those of related investigations reported in literature. Finally, it is discussed to which extent one's own voice should be considered in auditory virtual environments. [References: 24]
