Abstract

Hearing aid users suffering from tinnitus usually need an amplification device and additionally a tinnitus masker. Today, hearing aids are equipped with both functions, but in order to switch between these two functions a dedicated button has to be pressed manually. This is inconvenient.
In the following a novel solution is proposed combining the tinnitus and the amplification function, so that manual shifting is not necessary anymore. For this purpose, intelligent features, for example a hearing aid classifier can be used, deciding which function should be active dependent on the environment. The classifier separates the desired classes based on the features extracted from the input signal. Besides, there is a fader switching stepless between the two functions. For a better understanding, the following example is presented:

Self Learning and Multi-Mode Tinnitus Hearing Aid

Idea: Frank Naumann, DE-Erlangen; Johannes Lauer, DE-Erlangen

Hearing aid users suffering from tinnitus usually need an amplification device and additionally a tinnitus masker. Today, hearing aids are equipped with both functions, but in order to switch between these two functions a dedicated button has to be pressed manually. This is inconvenient.

In the following a novel solution is proposed combining the tinnitus and the amplification function, so that manual shifting is not necessary anymore. For this purpose, intelligent features, for example a hearing aid classifier can be used, deciding which function should be active dependent on the environment. The classifier separates the desired classes based on the features extracted from the input signal. Besides, there is a fader switching stepless between the two functions. For a better understanding, the following example is presented:

If a hearing aid user is reading a book in a quiet environment, the silence is detected by the classifier. As a consequence, the hearing aid user will just hear a noise covering the tinnitus produced by the tinnitus masker. Besides, if a hearing aid user has a conversation, the hearing aid will shift stepless to the amplification function as required. The interaction of the detection by the classifier and the adjusted settings is depicted in Figure 1.

As another option, the settings can be adjusted via sound level thresholds. This...
