  • Patent number: 11375325
    Abstract: A hearing device has a signal processor which has an adjustable parameter that has a given setting at a given time. The parameter is set depending on the situation by selecting a setting, depending on an environmental situation and by a learning machine. A current setting of the parameter can be rated by feedback from a user. In a first training procedure the learning machine is passively trained by negative feedback signals, by rating feedback from the user as dissatisfaction with the current setting and by assuming the user's satisfaction with the current setting as long as no feedback is given. In a second training procedure the learning machine is trained by changing the current setting independently of the feedback from the user and in spite of an assumed satisfaction with the current setting, so that the user is offered a different setting which can then be rated by feedback.

  • Patent number: 11330377
    Abstract: Disclosed are systems and methods for fitting a sound personalization algorithm using a two-dimensional (2D) graphical fitting interface. A calculated set of initial digital signal processing (DSP) parameters are determined for a given sound personalization algorithm, based on a user hearing profile. The initial DSP parameters are outputted to a 2D graphical fitting interface of an audio personalization application, wherein a first axis represents a level of coloration and a second axis represents a level of compression. A user input specifies a first 2D coordinate selected from a coordinate space presented by the 2D graphical fitting interface. A first set of refined DSP parameters is generated to apply a coloration and/or compression adjustment corresponding to the first 2D coordinate. The given sound personalization algorithm is parameterized with the first set of refined DSP parameters.

  • Patent number: 11323820
    Abstract: The invention relates to a mobile loudspeaker apparatus for playing back sound. Mobile loudspeaker systems are often disadvantageous in that they have a poor sound quality or require equipment for a good sound quality that is not easy to transport. A loudspeaker apparatus which firstly provides a good sound quality and secondly is also easily transportable is desirable. Previously, these two requirements were often mutually exclusive. By way of a bistable membrane, or a membrane that is stable in more than two states, said membrane being coupleable to the loudspeaker apparatus, it is possible to manage the balancing act between good transportability and a good sound quality of the loudspeaker apparatus. The bistable membrane can be changed from a stable operating state into a stable transport state. By way of a slight pressure at both ends of the bistable membrane, the latter can be rolled up and consequently changed into the transport state.
