METHOD FOR DIRECTIONAL SIGNAL PROCESSING FOR A HEARING INSTRUMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015451 titled 'METHOD FOR DIRECTIONAL SIGNAL PROCESSING FOR A HEARING INSTRUMENT

Simplified Explanation

The abstract describes a method for directional signal processing in a hearing instrument. It involves generating first and second input signals from a sound signal using input transducers. The first front intermediate signal and first rear intermediate signal are formed from these input signals. A first superposition of the first front intermediate signal and the first rear intermediate signal is created using a complex-value first superposition parameter, which is adapted based on the parameter itself. The resulting complex value of the first superposition parameter is then converted into a first alternative parameter and a second alternative parameter. An output signal is generated using the first alternative parameter, the limited second alternative parameter, and a superposition of the first and second input signals.

  • The method involves processing sound signals in a hearing instrument.
  • It uses input transducers to generate first and second input signals.
  • The first front intermediate signal and first rear intermediate signal are formed from the input signals.
  • A first superposition of the front and rear intermediate signals is created using a complex-value parameter.
  • The complex value of the parameter is adapted based on the parameter itself.
  • The adapted complex value is converted into first and second alternative parameters.
  • An output signal is generated using the alternative parameters and a superposition of the input signals.

Potential applications of this technology:

  • Hearing aids and other hearing instruments can benefit from directional signal processing to enhance sound quality and improve speech intelligibility.
  • This method can be used in noise-canceling headphones to improve the listening experience in noisy environments.
  • It can be applied in audio recording and broadcasting systems to selectively capture sound from specific directions.

Problems solved by this technology:

  • Directional signal processing helps to reduce background noise and improve the signal-to-noise ratio, making it easier for individuals with hearing impairments to understand speech.
  • It allows for better localization of sound sources, helping users to focus on specific sounds or conversations in complex auditory environments.

Benefits of this technology:

  • Improved speech intelligibility and sound quality for individuals with hearing impairments.
  • Enhanced listening experience in noisy environments.
  • Better localization of sound sources, leading to improved situational awareness and communication.


Original Abstract Submitted

a method performs directional signal processing for a hearing instrument. first and second input signals are generated by first and second input transducers, respectively, from a sound signal. the first front intermediate signal and a first rear intermediate signal are each formed from the first and second input signals. a first superposition of the first front intermediate signal and the first rear intermediate signal is formed by a complex-value first superposition parameter and is adapted based on the first superposition parameter. a complex value of the first superposition parameter resulting from the adaptation of the first superposition is converted into a first alternative parameter and a second alternative parameter. an output signal is generated based on the first alternative parameter, the limited second alternative parameter and a superposition of the first and second input signals.
