摘要： In a method of influencing the exhaust noise of a motor vehicle, a control unit generates noise package signals, the control unit transmits the noise package signals individually or so as to superimpose a basic signal to a loudspeaker associated with an exhaust branch of the motor vehicle, and the loudspeaker converts the individual noise package signals or the basic signal superimposed with the noise package signals into sound waves, with individual noise package signals being emitted by the loudspeaker as time-limited sound wave packages, so-called noise packages. Furthermore, an exhaust system is shown.

摘要： An acoustic apparatus includes a vibration part configured to generate an acoustic vibration, a tube having a cavity that faces the vibration part, and at least one open tube connected to the tube via a first open end and a second open end. A length of the at least one open tube is an integer-fold of substantially a half of a wavelength of a standing wave produced in the tube. The first open end is positioned substantially at an anti-node of the standing wave produced in the tube.

摘要： Techniques involve attenuating noise from engine exhaust from an engine. For example, an apparatus includes a first tube having an input end which receives the engine exhaust from the engine, and an output end which outputs the engine exhaust. The apparatus further includes a second tube which encircles the output end of the first tube. The second tube has an exhaust end through which the engine exhaust outputted by the output end of the first tube is allowed to escape, and a resonator end which is opposite the exhaust end. The apparatus further includes a reverse resonator disposed at the resonator end of the second tube. The reverse resonator defines a reverse resonator chamber and a reverse resonator chamber diameter which is larger than a second tube diameter defined by the second tube.

摘要： 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.
