Abstract (en)
[origin: WO9117638A1] The invention relates to a tinnitus masking device with one or more signal generators, an adjustable amplifier (2) and one or two electroacoustic converters (3) to convert electrical into acoustic signals and a voltage source, in which at least one of the signal generators (1) generates a continuously repeated pure sinusoidal sound signal slowly extending over the audible frequency range, the cycle time of which can be adjusted between 0.1 and 1 000 s.
