This paper presents an original mobile application for tinnitus sound therapy based on standard audiological diagnostic protocols and a recognized treatment method. The application comprises three main modules: audiometric tests with audiogram display, detection of tinnitus determinants, and sound filtering-based tinnitus therapy. In addition, a standardized questionnaire is included, allowing continuous monitoring of the effects of tinnitus on the patient’s quality of life. The entire system built around this mobile application serves as a proof-of-concept for an m-health solution designed to raise awareness of hearing health and provide appropriate on-the-go support. All use cases covered in the application follow standard clinical practice to ensure that real-world diagnostic and treatment scenarios are closely replicated. The proposed system thus provides the ability to quickly test for tinnitus-related health problems and enables personalized, continuous support through sound therapy.
