摘要：
A method of masking a persons tinnitus and a tinnitus masking system for use by a person having tinnitus are disclosed. The masking system (400) comprises a sound delivery system having left and right ear-level audio delivery devices (420). The sound delivery system is configured to deliver a masking sound to the person via the audio delivery devices such that the masking sound appears to originate from a virtual sound source location that substantially corresponds to a spatial location in 3D auditory space of a source of the tinnitus as perceived by the person. The masking sound is represented by left and right audio signals that are converted to audible sound by the respective audio delivery devices. Also disclosed are a method and a system for determining a spatial property of tinnitus as perceived by a person. The system comprises a sound generation system (400) that is operable to present test sounds to the person from a series of virtual sound source locations in 3D auditory space and a feedback system that is arranged to receive person feedback indicative of the virtual sound source location that most closely corresponds to the spatial location in 3D auditory space of the source of the tinnitus as perceived by the person and output spatial information indicative of the spatial location of the source of the tinnitus based on the persons feedback. A method and a spatial masking sound generation system for a person having tinnitus are disclosed. The masking sound generation system (400) comprises a sound processor that is arranged to receive a masking sound and spatial information indicative of the spatial location in 3D auditory space of the source of the tinnitus as perceived by the person, and which is further configured to modify the spatial playback properties of the masking sound based on the spatial information so as to generate a spatial masking sound for playback to the person via left and right ear-level audio delivery devices such that the sound appea
