If you have tinnitus the application asks you to identify its frequency via a simple a rapid test and immediately proposes a variety of natural sounds, specifically modified to mask the noise you are suffering. This application also rapidly analyses any environmental noise with your device microphone and immediately proposes the right variety of natural sounds. Psychoacoustic algorithms of sound masking are used to better hide annoying noise/tinnitus and give immediate comfort to the user via headphones or speakers. It is known that if the background noise is too low it worsens any problem of tinnitus and also of insufficient soundproofing: sometimes too much soundproofing creates a silence that enhances small noises. An economic and appreciable solution is the use of relaxing natural sounds (rain, waves, water, etc.) to hide noise disturbances and bring people back to a more human sound dimension.
