The invention relates to a method (30) for damping and/or amplifying a sound introduced into a passenger compartment (10) of a motor vehicle, in particular an electrically driven motor vehicle, said sound being generated (32) by a sound source (22) arranged outside of the passenger compartment (10). A correction signal is generated (40) by means of correction signal means (16) which are paired with the sound source (22) and/or a sound-transmitting structure (20) of the motor vehicle, and the correction signal is determined (38) such that the sound is introduced into the passenger compartment (10) in a damped or amplified state.

Aspects of the present invention relate to an active noise system (4), a vehicle (1) with an active noise system (4), a method for controlling an active noise system (4), a computer program for controlling an active noise system (4) and an active noise controller (40). The wading detection system (3) includes sensors (30, 31, 32, 33) for detecting a wading depth and a wading detection controller (34). The active noise system (4) includes speakers (41, 42) for modifying the exhaust noise emitted from the vehicle (1). The wading detection controller (34) is operable to detect or anticipate a predetermined wading depth (W.sub.1, W.sub.2) at which the speakers (41, 42) will come into contact with the water. The active noise controller (40) is configured to deactivate the speakers (41, when the predetermined wading depth (W.sub.1, W.sub.2) is detected or anticipated by the wading detection controller (34).

A sound system for a motor vehicle exhaust gas system for emitting emulated engine sounds, including at least one loudspeaker and at least one housing accommodating at least one loudspeaker. The housing is mounted separately from a motor vehicle exhaust gas system in terms of the routing of an exhaust gas flow, at least one sound guidance tube having an outlet zone being mounted on the housing.

Embodiments include a vehicle comprising an audio system configured to create a plurality of audio zones within a vehicle cabin, and at least one display communicatively coupled to the audio system. The display is configured to display a separate user interface for each audio zone. Each user interface comprises an engine sound control and a cabin noise control for adjusting an audio output provided to the corresponding audio zone. Embodiments also include a method of providing user-controlled sound isolation in a plurality of audio zones within a vehicle. The method comprises presenting, for each audio zone, a user interface including an engine sound control and a cabin noise control, and generating an audio output for each audio zone based on a first value received from the engine sound control and a second value received from the cabin noise control of the corresponding user interface.

A method of generating a drive signal for a loudspeaker in an exhaust system of an engine of a vehicle or inside or outside a passenger cell includes providing a predetermined source signal for a desired additional sound in a time domain comprising a plurality of signal components of different frequencies; analyzing the source signal based on a phase of the source signal and/or a phase of at least one oscillation in the source signal; identifying a phase of engine noise and/or a phase of at least one oscillation existing in engine noise; shifting the phases of the source signal and/or the oscillation existing in the source signal based on phases identified in engine noise and/or in oscillation existing in engine noise, the relationship of phases of individual oscillations of the source signal among each other being preserved; and generating the drive signal based on the phase-shifted source signal.

An exemplary engine noise control includes directly picking up engine noise from an engine of a vehicle at a pick-up position to generate a sense signal representative of the engine noise, and active noise control filtering to generate a filtered sense signal from the sense signal. The control further includes converting the filtered sense signal from the active noise control filtering into anti-noise and radiating the anti-noise to a listening position in an interior of the vehicle. The filtered sense signal is configured so that the anti-noise reduces the engine noise at the listening position.

An arrangement (1) of an electroacoustic actuator (2) on a vehicle structure (3) of a motor vehicle, has a housing (4), in which at least one loudspeaker (7) is arranged, which separates a front volume (8) from a rear volume (9) in the housing (4). The actuator (2) has a sound emission pipe (5), which projects outwards from the housing (4) and which is fluidically coupled with the front volume (8). A reduced introduction of noise into the vehicle arises when the actuator (2) is held on the vehicle structure (3) with a plurality of holding devices (19), which are arranged on the housing (4) in a circumferential direction (20) of the housing (4) spaced apart from one another. Each holding device (19) is designed as springy in a holding direction (21) and as rigid transversely thereto.
