Abstract: A device is provided for influencing the passenger compartment noise in a motor vehicle includes, but is not limited to a noise signal generator for generating an offsetting noise signal, which includes, but is not limited to a control input for receiving a control signal that is representative of the engine load of the motor vehicle, and a loudspeaker for receiving the offsetting noise signal and emitting an offsetting noise into the passenger compartment of the motor vehicle. The noise signal generator furthermore includes, but is not limited to an input for a temperature signal of a temperature sensor and is equipped to generate the offsetting noise signal as a function of a signaled temperature.

Abstract: A method of masking sounds associated with a vehicle is provided. The method includes performing on processing circuitry, monitoring of vehicle data. A tonal disturbance type and a tone to mask associated with the tonal disturbance type are identified based on the vehicle data. A shaped band of sounds is determined based on the tone to mask. The shaped band of sounds covers a range of frequencies around the tone to mask. The shaped band of sounds is applied to an audio output of the vehicle.

Abstract: An acoustic warning device for a vehicle is disclosed. The acoustic warning device includes an air suction device having a suction tube, and a filter housing having a filter and a sound generating device which is arranged therein. The sound generating device is arranged between suction tube and filter with respect to a flow direction of the air. The sound generating device firstly emits the acoustic signal into a spatial volume of the filter housing. An additional chamber volume serves as a band-pass filter for the sound waves emitted from the sound generating device. The acoustic warning device may further include a sound source arranged outside the filter housing to generate sound signals with higher frequencies than emitted from the filter housing. By the combination of these two sound generating devices, an efficient emission of low-frequency and also of high-frequency sound signals is therefore possible.
