Abstract: A system and method for accurately estimating engine noise at a virtual microphone location, such as an occupant's ear position, in an acoustic space in order to enhance performance of an Engine Order Cancellation (EOC) system is provided. A set of weights and transfer functions that are dependent on various vehicle parameters, such as frequency, load, and speed, may be employed to estimate noise at a position where there are no physical microphones present. The accurate estimation of engine noise at virtual location, such as an occupant's ear position, may be achieved using a frequency dependent weighted sum of filtered and unfiltered error signals measured at microphones mounted at various locations inside an acoustic space, such as a vehicle cabin, which may not be located near virtual location.

Abstract: A road noise cancellation (RNC) system may include a controller and attenuator for reducing the audibility of the noise floor caused by the system's vibration sensors. A level of anti-noise at a location in a passenger cabin that may be attributed to the sensor noise floor may be estimated. An actual sound level in the passenger cabin may be measured or estimated, with the sensor noise floor component algorithmically removed. The difference in levels may be compared to a predetermined threshold to determine an amount of attenuation, if any, to be applied to an anti-noise signal to reduce audibility.

Abstract: Apparatus and associated methods relate to training FIR filter coefficients by deconvolving a first input signal and a second input signal in the frequency domain, both of the signals being generated in response to an undetermined broadband excitation applied to an acoustic body instrument, until a fidelity of the second signal convolved with the trained coefficients meets predetermined fidelity criteria relative to the first signal. In an illustrative example, a musical instrument pickup signal and a microphone signal from the musical instrument may be sampled, segmented, and transformed to the frequency domain. FIR filter coefficients may be, for example, trained by block deconvolution in the frequency domain of the microphone signal and the pickup signal. In various examples, the trained FIR filter coefficients may adapt the pickup signal to mimic microphone performance, including full-body acoustic content.
