Abstract

Disclosed is a vehicular acoustic environmental system including a speaker arrangement disposed in a headrest of a seat of a driver and/or passenger of the vehicle. Furthermore, the headrest is provided with a microphone arrangement that detects sounds in a proximity to one or more ears of the driver and/or passenger to generate a corresponding microphone signal, and the acoustic environmental system includes a signal processing arrangement that adjusts in operation a gain and/or a phase shift, as a function of signal frequency, applied to the microphone signal to generate an output signal to excite, in operation, the speaker arrangement, wherein the gain and/or the phase shift are adjusted to provide an anti-sound reduction in perceived sound at the one or more ears of the driver and/or passenger. Optionally, vehicular acoustic environmental system additionally, or alternatively, includes a vibration sensor arrangement that is mounted to a chassis of the vehicle to sense in operation vibrations in the chassis to generate corresponding sensed vibration signals, and a vibration actuation transducer arrangement coupled to the chassis, and wherein the signal processing arrangement adjusts a gain and/or a phase shift, as a function of signal frequency, applied to the sensed vibration signals to generate an output signal for exciting, in operation, the vibration actuation transducer arrangement, wherein the gain and/or the phase shift are adjusted to provide an anti- sound reduction in perceived sound at the one or more ears of the driver and/or passenger.
