Abstract：To solve the effectiveness and audibility of traditional masking therapy in tinnitus treatment,we proposed a multi-track personalized tinnitus masking therapy sound(MT-PTMTS)synthesis method based on phase vocoder(PV)and gradient blending algo-rithm.Based on the biological natural sound database,and the environmental background natural sound database.PV was used for tone transformation.The iterated function system(IFS)fractal mapping algorithm was used to synthesize personalized biological natural sounds that could match the frequency band of patients'tinnitus with controllable duration and were similar without repetition.Finally,the environmental background natural sounds that were spliced by gradual mixing algorithm were added.The experimental results showed that MT-PTMTS could effectively match the tinnitus frequency band of patients,and it conformed to the 1/f fluctuation.In ad-dition,MT-PTMTS could effectively suppress the corresponding frequency band tinnitus after input to the tinnitus model.The results show that the therapeutic sound is pleasant and natural,and has certain reference value for tinnitus treatment.
