Latest Patents

One of Dreβler's latest patents is a method for reducing noise using trainable models. This innovative approach aims to enhance the effectiveness of noise reduction algorithms in hearing apparatuses. The method involves modeling the input signal with both a wanted signal model and a noise signal model. Additionally, a data logging unit records the signal statistics of the input signal. This allows for continuous adaptation of the models used, ensuring that they meet the current needs of the hearing apparatus user.

Another significant patent is a multi-stage estimation method for noise reduction in hearing apparatuses. This invention improves noise reduction for signals that may contain speech at times. It features a hearing device equipped with a first estimation device that estimates an initial value of the input signal using a first estimation algorithm. A second estimation device, parameterized with the first estimated value, then estimates a second value of the input signal. This two-stage estimation method allows for adaptive noise reduction that is always aligned with the input signal.
