  • Publication number: 20250247658
    Abstract: A method for personalized sound modification, with a personal sound system having a microphone; a user device which includes a processor, computer readable medium, and optionally the microphone; and a sound output device; is provided. The method includes: providing a user hearing profile including lower and upper limits of the user's auditory dynamic range at a plurality of sound frequencies, prepared with the personal sound system; receiving a sound signal from the microphone; optionally separating the sound signal into a plurality of frequency channels; amplifying or attenuating sound frequencies in the sound signal which have a volume level outside the lower or upper limits of the user's auditory dynamic range, respectively, and forming a modified sound signal with which the sound output device will produce sounds within the user's auditory dynamic range; and providing the modified sound signal to the sound output device.

  • Patent number: 12143780
    Abstract: A portable calibration system is disclosed that calibrates an audio equipment without using a dedicated sound level meter. The calibration system comprises a coupler configured to couple a transducer to an energy sensor, where an output of the transducer is provided to the energy sensor via the coupler, an analyzer module configured to receive information from the energy sensor regarding the output of the transducer, a processor, in the analyzer module, configured to process the information to provide a result of a calibration for the audio equipment with respect to expected results, and a display configured to display the result of the calibration.

  • Patent number: 8942815
    Abstract: A system and method that enhance the performance of cochlear implant signal processing in an amplification device. The system utilizes a signal input device that picks up the sounds from the environment or other hearing or audio devices and feeds the incoming signal into a front-end signal processor. The front-end processor pre-processes the signals and feeds them into a cochlear implant signal processor. The system may also insert a front-end processor into multiple signal processing stages of a cochlear implant signal processor with the front-end processor “sandwiched” between the multiple signal processing stages of the cochlear implant signal processors. The system may also insert a front-end processor into multiple signal processing stages of a cochlear implant signal processor with the front-end processor being either an integrated part of the cochlear implant signal processor or a functionally distinctive part for bilateral cochlear implants.

    Abstract: A system and method that enhance the performance of cochlear implant signal processing in an amplification device. The system utilizes a signal input device that picks up the sounds from the environment or from other hearing or audio devices and feeds the incoming signal into a front-end signal processor, which can be signal processors from hearing aids, hearing protectors or other audio devices. The front-end processor preprocesses the signals and feeds them into a cochlear implant signal processor. The front-end processor may have multiple signal feeding and signal extraction points, other than the two ends, to which connections can be made to feed signals into and extract signals from the front-end processor. The system may also insert a front-end processor into multiple signal processing stages of a cochlear implant signal processor with the front-end processor “sandwiched” between the multiple signal processing stages of the cochlear implant signal processors.
