TINNITUS SIMULATOR Russian patent published in 2024 - IPC A61B5/12 G09B23/28 

FIELD: medical equipment.

SUBSTANCE: invention can be used for imitation, modeling and analysis of human ear noise. Ear noise simulator comprises serially connected periodic function address sensor, periodic function calculating unit, switch, first multiplier, first adder, first phase computing unit, first amplitude computing unit, second multiplier, first digital-to-analogue converter, first low-pass filter, as well as series-connected pseudorandom sequence length sensor and first pseudorandom sequence generating unit, series-connected signal duration code sensor and a divider with a variable division ratio, a frequency range code sensor, an initial frequency code sensor, the first amplitude-modulating function address sensor and the first amplitude-modulating function calculation unit are connected in series. Simulator also comprises series-connected first intensity code sensor, first controlled attenuator, second adder, series-connected second pseudorandom sequence generating unit, second phase computing unit, second amplitude computing unit, third multiplier, second digital-to-analogue converter, a second low-pass filter, a second controlled attenuator, a second amplitude-modulating function address sensor, a second amplitude-modulating function calculating unit, a second intensity code sensor, all connected in series.

EFFECT: providing the possibility of forming an acoustic image of human ear noise based on their subjective sensations.
