Method of generating sounds for reducing an effect of tinnitus and tinnitus control instrument performing the same
A method of generating sounds for reducing an effect of tinnitus is disclosed. The method includes the following steps: acquiring a sound frequency of a tinnitus sound of a user, and playing a plurality of pure tones within a frequency range during a playback time, wherein the plurality of pure tones include a plurality of first pure tones and a plurality of second pure tones; the plurality of first pure tones and the sound frequency are located at a first frequency area, and the plurality of second pure tones are located at a second frequency area; the first frequency area covers X Hz, where 100≤X≤12000, the second frequency area covers the remaining portion of the frequency range excluding the first frequency area, and the plurality of first pure tones accounts for M % of the plurality of pure tones, where 50<M≤90.
1. A method of generating sounds for reducing an effect of tinnitus, applied to a tinnitus control instrument, wherein the tinnitus control instrument comprises a speaker, the method comprising the following steps:
acquiring a sound frequency of a tinnitus sound of a user; and
controlling the speaker to play a plurality of pure tones within a frequency range during a playback time, wherein the plurality of pure tones comprises a plurality of first pure tones and a plurality of second pure tones; the sound frequency and the plurality of first pure tones are located at a first frequency area, and the plurality of second pure tones are located at a second frequency area; the first frequency area covers a range of X Hz, where 100≤X≤12000, the second frequency area covers the remaining portion of the frequency range excluding the first frequency area, and the plurality of first pure tones account for M % of the plurality of pure tones, where 50<M≤90, wherein:
the sound frequency is F Hz, the frequency range covers from 0.25F Hz to 4F Hz, and the first frequency area covers from 0.5F Hz to 2F Hz, and
the plurality of second pure tones having frequencies ranging from 0.25F Hz to 0.5F Hz are chord tones of the same chord, the plurality of first pure tones having frequencies ranging from 0.5F Hz to F Hz are chord tones of the same chord, the plurality of first pure tones having frequencies ranging from F Hz to 2F Hz are chord tones of the same chord, and the plurality of second pure tones having frequencies ranging from 2F Hz to 4F Hz are chord tones of the same chord.
2. The method as claimed in claim 1 , wherein the frequencies of the plurality of pure tones are tuned with 12-tone equal temperament.
3. The method as claimed in claim 1 , wherein the plurality of pure tones are generated randomly.
4. The method as claimed in claim 3 , wherein the probability of generating the plurality of first pure tones is 2 times the probability of generating the plurality of second pure tones.
5. A tinnitus control instrument, used for playing a sound to reduce a tinnitus effect of a user, the tinnitus control instrument comprising:
a speaker; and
a controller, electrically connected to the speaker, the controller comprising:
tinnitus sound frequency acquisition module, used for acquiring a sound frequency of a tinnitus sound of the user; and
a sound generation module, used for controlling the speaker to play a plurality of pure tones within a frequency range during a playback time, wherein the plurality of pure tones comprise a plurality of first pure tones and a plurality of second pure tones; the sound frequency and the plurality of first pure tones are located at a first frequency area, and the plurality of second pure tones are located at a second frequency area; the first frequency area covers a range of X Hz, where 100≤X≤12000, the second frequency area covers the remaining portion of the frequency range excluding the first frequency area, and the plurality of first pure tones account for M % of the plurality of pure tones, where 50<M≤90, wherein:
the sound frequency is F Hz, the frequency range covers from 0.25F Hz to 4F Hz, and the first frequency area covers from 0.5F Hz to 2F Hz, and
the plurality of second pure tones having frequencies ranging from 0.25F Hz to 0.5F Hz are chord tones of the same chord, the plurality of first pure tones having frequencies ranging from 0.5F Hz to F Hz are chord tones of the same chord, the plurality of first pure tones having frequencies ranging from F Hz to 2F Hz are chord tones of the same chord, and the plurality of second pure tones having frequencies ranging from 2F Hz to 4F Hz are chord tones of the same chord.
6. The tinnitus control instrument as claimed in claim 5 , wherein the frequencies of the plurality of pure tones are tuned with 12-tone equal temperament.
7. The tinnitus control instrument as claimed in claim 5 , wherein the plurality of pure tones are generated randomly.
8. The tinnitus control instrument as claimed in claim 7 , wherein the probability of generating the plurality of first pure tones is 2 times the probability of generating the plurality of second pure tones.
