Various systems and methods for providing audio obstruction effects in 3D parallax user interfaces are described herein. An apparatus comprises: a presentation module to present a 3D parallax user interface on an electronic device, the 3D parallax user interface including a foreground layer and a background layer, the foreground layer having a foreground user interface component and the background layer having a background user interface component, the foreground user interface component obstructing at least a portion of the background user interface component; a receiving module to receive a signal to generate an audio notification for the background user interface component; and an audio effect module to: determine an audio effect to apply to the audio notification, the audio effect based on the position of the background user interface component in relation to the foreground user interface component; and apply the audio effect to the audio notification.
