摘要： The present disclosure is directed to a system and a method for spectral shaping of vehicle noise cancellation. In an example implementation, the method includes determining a center frequency of an expected tonal peak within a selected noise band based upon vehicle data, generating a noise cancellation signal using a weighted shaping filter to shape the noise band, and outputting the noise cancellation signal to smooth the expected tonal peak.

摘要： A panel assembly includes a first panel defining a surface, and a boom attenuation panel. The boom attenuation panel includes a circumferential edge, and a central portion. The boom attenuation panel is attached to the surface of the first panel, along the circumferential edge of the boom attenuation panel. The central portion of the boom attenuation panel is spaced from the surface of the first panel a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel. The gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel. Movement of the gas increases the effective acoustic mass of the boom attenuation panel, and damped the wave-like motion of the first panel, which operates to reduce noise generated from the wave-like motion of the first panel.

摘要： A wheel assembly for a vehicle and a method of manufacturing the wheel assembly for the vehicle are disclosed. The wheel assembly includes a rim and a tire. The tire includes a distal wall, a first side wall and a second side wall, with the first and second side walls extending from the distal wall and each of the side walls attached to the rim such that the distal wall is spaced from the rim to define an interior cavity between the tire and the rim. The wheel assembly also includes a resonator defining a hole such that the resonator presents an inner wall defining a boundary of the hole. The hole cooperates with the interior cavity. The resonator includes an insert mounted to the inner wall. The insert defines an aperture in fluid communication with the interior cavity for attenuating sound produced inside the interior cavity.

摘要： A method of masking road noise for a vehicle includes monitoring, through a processor, one or more vehicle mounted transducers for noise produced by an interaction between the vehicle and a road surface, detecting, through the processor, an audible signal having one of an undesirable frequency and an undesirable magnitude associated with the interaction between the vehicle and the road surface, generating, through the processor, a masking signal having a frequency that will mask the audible signal having the one of the undesirable frequency and undesirable magnitude, and emitting the masking signal through one or more vehicle speakers.
