    摘要： An audio processing system may selectively identify certain environmental sounds and playing back these sounds, or a representation of these sounds, in the vehicle's cabin. The audio processing system may filter the environmental sounds to identify a particular sound that matches an event such as a bouncing ball, squealing tires, footsteps, and the like. The audio processing system may then provide an audio alert to an occupant in the vehicle. For example, the system may process the identified sound (e.g., amplify and/or isolate the sound) and use a speaker to output the processed sound into the interior of the vehicle. In another embodiment, the audio processing system may use environmental sounds as an audio masking sound for creating privacy zones within the vehicle. The audio processing system may filter the environmental sounds to identify a continuous sound which is then output to generate the privacy zones.

    摘要： An active noise control apparatus includes a first active noise controller for generating a first canceling signal for a first noise type, a second active noise controller for generating a second canceling signal for a second noise type that is different from the first noise type, a mixer for mixing the first canceling signal and the second canceling signal into a mixed canceling signal, a canceling sound output unit for outputting a canceling sound based on the mixed canceling signal, and an amplitude suppressor for suppressing the amplitude of the second canceling signal depending on the amplitude of the first canceling signal.

    摘要： An active vibration noise control apparatus is provided. When a vehicle speed changes thereby to change frequency characteristics (peak-amplitude frequency) of vibration noise, the active vibration noise control apparatus refers to a vehicle speed versus frequency correspondence table representing a correspondence relation between a vehicle speed of a vehicle and a frequency of a reference signal, and changes the frequency of the reference signal that is used by an adaptive notch filter.

    摘要： An active vibration noise control device cancels vibration noise by making plural speakers generate control sounds. The active vibration noise control device selects one or more speakers which output the control sounds, from plural speakers, based on a relationship between (1) a first phase difference which corresponds to a difference between phase characteristics of the vibration noise from a vibration noise source to an evaluation point and phase characteristics of the vibration noise from the vibration noise source to a pseudo evaluation point and (2) a second phase difference for each of the plural speakers corresponding to a difference between phase characteristics of the control sound from the speaker to the evaluation point and phase characteristics of the control sound from the speaker to the pseudo evaluation point. Therefore, it stably decreases the vibration noise at the pseudo evaluation point independently of a frequency band of the vibration noise.

    摘要： A subtractor subtracts a first control signal output from a first bandpass filter from an error signal, and supplies a differential signal to a second bandpass filter. The second bandpass filter, which has a central frequency of 70 Hz, is affected by an operation of the first bandpass filter, i.e., a first control signal, which has a central frequency of 40 Hz. The first bandpass filter is not affected by an operation of the second bandpass filter, i.e., the second control signal.
