2. The method of claim 1, wherein obtaining audio information of an environment in which the tinnitus patient is located, and determining whether the audio information has a masking effect on tinnitus frequency and loudness comprises:
detecting whether sound source information exceeding a preset loudness range exists in the audio information, and if so, not executing masking signal output;
if sound source information exceeding a preset loudness range does not exist, detecting whether sound source information which is consistent with tinnitus frequency and exceeds tinnitus loudness exists in the audio information, and if so, not executing masking signal output;

eliminating noise audio in the audio information of the environment where the tinnitus patient is located, wherein the elimination basis of the noise audio is preset noise information;
obtaining loudness peak information of the audio information in different frequency ranges, calculating the dispersion degree of the loudness peak information, and determining the audio information with the minimum dispersion degree of the loudness peak information as a preset stable audio;
and obtaining stable audio by self-adaptive filtering processing according to the audio information of the environment where the tinnitus patient is located.
4. A method according to claim 1 wherein processing the stabilized audio into a masking signal that adapts the tinnitus degree information is adjusting the signal-to-noise ratio and loudness of the stabilized audio so that the frequency of the masking signal is in the same threshold range as the tinnitus frequency and the loudness of the masking signal is greater than the tinnitus loudness.

the fitting module is used for acquiring tinnitus degree information of a tinnitus patient, and the tinnitus degree information comprises tinnitus frequency and loudness;
the detection module is used for acquiring the audio information of the environment where the tinnitus patient is located and judging whether the audio information causes masking effect on the tinnitus frequency and loudness;
the picking module is used for picking stable audio in the environmental audio information of the tinnitus patient if the tinnitus frequency and loudness cannot cause masking effect;
an output module for processing the stabilized audio into a masking signal adapted to the tinnitus degree information for the hearing assistance device to output the masking signal.
6. The apparatus of claim 5, wherein the detection module comprises:
the first detection submodule is used for detecting whether sound source information exceeding a preset loudness range exists in the audio information or not, and if the sound source information exists, the masking signal output is not executed;
the second detection submodule is used for detecting whether sound source information which is consistent with tinnitus frequency and exceeds tinnitus loudness exists in the audio information or not if sound source information which exceeds a preset loudness range does not exist, and does not execute masking signal output if the sound source information exists;
and the determining module is used for determining that the audio information cannot cause a masking effect on the tinnitus frequency and the loudness if no sound source information which is consistent with the tinnitus frequency and exceeds the tinnitus loudness exists.
7. The apparatus of claim 5, wherein the pick-up module comprises:
the noise elimination module is used for eliminating noise audio in the environmental audio information of the tinnitus patient, and the elimination basis of the noise audio is preset noise information;
the calculation module is used for acquiring loudness peak information of the audio information in different frequency ranges, calculating the dispersion degree of the loudness peak information, and determining the audio information with the minimum dispersion degree of the loudness peak information as a preset stable audio;
and the processing module is used for obtaining stable audio through self-adaptive filtering processing according to the audio information of the environment where the tinnitus patient is located.
8. The apparatus of claim 5 wherein the processing of the stabilized audio into a masking signal that adapts the tinnitus degree information is to adjust the signal-to-noise ratio and loudness of the stabilized audio such that the frequency of the masking signal is in the same threshold range as the tinnitus frequency and the loudness of the masking signal is greater than the tinnitus loudness.
9. A hearing device based on a masking therapy system, comprising:
a processor;
a memory for storing the processor-executable instructions;
wherein the processor is configured to perform the steps of the method of any one of claims 1 to 4.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 4.
