From: Effects of sound source localization of masking sound on perception level of simulated tinnitus

Schematic description of Experiment 2. (A) Inside-head (monaurally recorded) masking noise can be heard inside the head, whereas (B) Outside-head (binaurally recorded) masking noise can be heard outside the head. The blue splash means the masking noise, while the lightning shape means the simulated tinnitus.
