Embodiment Construction

[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] The present invention is different from using single-frequency sound or narrow-band noise as the masking signal source in the prior art, but uses natural sounds such as running water, forest, and birdsong as the masking signal source, so that the wearer's hearing experience is better while masking the tinnitus. For comfort, I am more willing to wear it for a long time, so as to achieve a better effect of relieving tinnitus. Using linear frequency shifting technology, personalized masking signals can be generated according to the needs of different tinnitus patients, while avoiding complicated calculation methods, and can be realized with simple and relatively cheap equipment, which will benefit more tinnitus patients. The system has high control precision and stable performance.

Abstract

The invention relates to a tinnitus treatment device and a masking sound signal synthesizing method. The tinnitus treatment device comprises a signal control module, a signal processing module and a signal output module. The signal control module selects a masking sound type according to basic masking signals, determines a tinnitus frequency band and controls the volume of masking sound. The signal processing module determines a target frequency band according to the tinnitus frequency, moves the frequency band of the masking sound to a frequency band with the central frequency of the target frequency band as the center and synthesizes masking sound signals. The signal output module outputs the volume of the masking sound signals according to the volume of the masking sound. The device can reduce the disturbance degree of masking sound while remitting tinnitus; the tinnitus treatment device is simple to use and low in cost and meets the requirements of more patients with tinnitus; the tinnitus treatment device also improves the difference masking control precision.

Description

technical field [0001] The present invention relates to a device for treating or alleviating tinnitus, in particular to a tinnitus treatment device and a method for synthesizing masking sound signals. Background technique [0002] The causes of tinnitus are very complicated, and currently there is no specific drug or surgical treatment for tinnitus. There are two main types of tinnitus treatment methods currently used: tinnitus masking therapy and habituation therapy. Tinnitus masking therapy is to use other external sounds to mask the tinnitus and reduce the impact of tinnitus on the patient. Masking effects are divided into active mitigation and passive mitigation. The so-called active relief refers to the disappearance of tinnitus during the sounding period; the passive relief refers to the disappearance of tinnitus after the masking ends. [0003] It is generally believed that active relief is most easily obtained at a frequency similar to tinnitus. Therefore, current...
