  • Publication number: 20240194216
    Abstract: A method for adjusting the clarity of an audio output in a changing environment, including: receiving a content signal; applying a customized gain to the content signal; and outputting the content signal with the customized gain to at least one speaker for transduction to an acoustic signal, wherein the customized gain is applied on a per frequency bin basis such that frequencies of a lesser magnitude are enhanced with respect to frequencies of a greater magnitude and an intelligibility of the acoustic signal is set approximately at a desired level, wherein the customized gain is determined according to at least one of a gain applied to the content signal, a bandwidth of the content signal, and a content type encoded by the content signal.
    Type: Application

  • Patent number: 10020788
    Abstract: An active sound management system comprises a transducer that senses an actual sound or vibration from a sound generating source and generates a transducer signal in response to sensing the actual sound or vibration; a harmonic extractor device that extracts a plurality of harmonics from the transducer signal; and a harmonic modifier device that adjusts a feature of the extracted harmonic to be within a predetermined threshold with respect to a target harmonic corresponding to a desired sound.

  • Patent number: 8892046
    Abstract: In an aspect, in general, an automobile communication system includes a first signal input for receiving an input signal from a sensor, a second signal input for receiving a first signal representing a rotational frequency associated with a portion of an engine of the automobile, an engine noise estimation module, and a transmitter. The engine noise estimation module is configured to determine an estimate of an engine-related component of the input signal based on the input signal and the first signal and to form a modified input signal. The engine noise estimation module includes a signal combination module configured to form the modified input signal, including combining the estimate of the engine-related component with the input signal. The transmitter is configured to transmit the modified input signal as part of an outgoing communication.
