Abstract: A vehicle includes an engine and/or powertrain producing noise that is audible in a passenger compartment of the vehicle when the engine and/or powertrain is running. An active noise control arrangement includes a first loudspeaker disposed within a passenger compartment of the vehicle. A digital signal processor receives audio data and transmits an audio signal to the first loudspeaker dependent upon the audio data. A microphone is disposed within the passenger compartment and converts the sound from the first loudspeaker and the noise within the passenger compartment into a microphone signal. The microphone signal is transmitted to the digital signal processor, and the digital signal processor modifies the audio signal such that the audio signal attenuates the noise in the passenger compartment. A vehicle processor transmits a simulated noise signal to a second loudspeaker for use in testing effectiveness of the active noise control arrangement in attenuating noise when the engine and/or powertrain is not running and not producing noise.

Abstract: A personal audio device, such as a wireless telephone, includes an adaptive noise canceling (ANC) circuit that adaptively generates an anti-noise signal from a reference microphone signal and injects the anti-noise signal into the speaker or other transducer output to cause cancellation of ambient audio sounds. An error microphone is also provided proximate the speaker to measure the ambient sounds and transducer output near the transducer, thus providing an indication of the effectiveness of the noise canceling. A processing circuit uses the reference and/or error microphone, optionally along with a microphone provided for capturing near-end speech, to determine whether the ANC circuit is incorrectly adapting or may incorrectly adapt to the instant acoustic environment and/or whether the anti-noise signal may be incorrect and/or disruptive and then take action in the processing circuit to prevent or remedy such conditions.

Abstract: The method of noise attenuation comprises the steps of generating a noise canceling signal based on an environmental assumption, assessing the environmental assumption of the control unit, and altering the noise canceling signal based on the assessment. Assessing may comprise the step of comparing the environmental assumption with actual environmental data, including the step of generating a test sound wave to obtain actual environmental data. The test sound wave is then compared to a model of the sound wave based on the environmental assumption. This method is embodied in a system that includes an air induction body, a speaker in proximity to the air induction body, a microphone in communication with the speaker, a reference sensor, and a control unit with a noise cancellation feature with an environmental assumption. The control unit is in communication with the speaker, reference sensor, and the microphone and assesses the environmental assumption in light of actual environmental data.

Abstract: A method of operating an audio system in a vehicle includes providing m number of microphones disposed within a passenger compartment of the vehicle. The microphones produce a plurality of microphone signals. Within the passenger compartment of the vehicle, k number of loudspeakers are provided. A plurality of convergence factors μ for use in performing active noise control are estimated. The estimating includes calculating an Eigen value λ(ω) of an autocorrelation matrix of a passenger compartment transfer function as λ k ⁡ ( ω ) = A k ⁡ ( ω ) 2 2 , wherein Ak(ω) is the frequency response of the passenger compartment transfer function. A frequency ωmin of a local minimum of λ(ω) is determined. A largest stable value for μMax(ωmin) is found by experimentation, wherein a rotational speed of an engine of the vehicle, expressed in revolutions per minute, frpm=2πωmin. A calibration factor is calculated as L=λ(ωmin)μMax(ωmin). All values of μMax(ω) are estimated as μMax ⁡ ( ω ) = L λ ⁡ ( ω ) . A plurality of active noise controlled audio signals are transmitted to the loudspeaker. The active noise controlled audio signals are dependent upon the microphone signals and the estimated convergence factors.
