The creation of a sound simulation system for people affected by tinnitus

Abstract [en]

Tinnitus is a medical condition that manifests itself as a ringing, beeping, or humming noise to the affected person. The intention of this project is to help people with tinnitus recreate the sound they hear inside their heads. This is done to help increase the understanding of tinnitus to unaffected people. Within the project a sound simulation system has been created, where the sound can be tuned to match the sound of an instance of tinnitus with adjustable parameters and a plot to help visualize the sound. In the sound simulation system there are a few different parameters that can be changed. There is a sinusoid tone, a distorted sinusoid tone and two changeable coloured noise. The coloured noise is created by filtering white noise with an infinite impulse response (IIR) bandpass filter. The actual sound simulation system is implemented in MATLAB and the user interface is made in Java as a remote tool with the ability to access the sound simulation system via the Internet.
