Sumary : 

In an experimental context, the use of headphones allows for controlling the acoustic cues delivered to a listener. It is even possible to simulate a source played in a room by convolving a sound with its impulse response. However, listening through headphones differs from an ecological situation in which a source exists in the listener's environment and represents the point of origin of their percepts. This could lead to a disruption in the brain- body-environment relationship. The aim of this thesis is to study the effects of listening through headphones on the evaluation of distance and perceived externalisation compared to listening sounds coming from a real source, using behavioural measures and brain activity recording techniques (EEG).
