Active noise cancelling (ANC) is a software process that uses existing in-vehicle infotainment hardware to eliminate undesirable noise within the interior of a vehicle. This elimination technique is known as harmonic order reduction, where unwanted audio signals are identified by sensors and filtered out of the overall interior vehicle sound. [3]
Soundaktor is a vehicle audio system used to simulate engine noise in the cabin of some Volkswagen automobiles. It consists of a speaker mounted on the firewall between the engine and the cabin, which adds noise to the cabin in order to replicate the driving experience of older vehicles that had lower levels of sound insulation.
As a result of increased sales of full electric vehicle and hybrid electric vehicles in several countries, some members of the blind community have raised concerns about the noise reduction when those vehicles operate in all-electric mode, as blind people or the visually impaired consider the noise of combustion engines a helpful aid while crossing streets and think quiet hybrids could pose an ...
For the 2015 Ford Mustang EcoBoost Fastback and EcoBoost Fastback Premium, an "Active Noise Control" system was developed that amplifies the engine sound through the car speakers. A similar system is used in the F-150 pickup truck. Volkswagen uses a Soundaktor, a special speaker to play sounds in cars such as the Golf GTi and Beetle Turbo.
Sound redirection: One of the obvious ways to reduce the received sound level of an observer is to place the observer out of the path of the highest amplitude sounds. For example, in the area around a jet engine, the sound power levels can be expected to be largest (i.e., loudest) directly in line with the jet's exhaust. Observations ...
This list of car audio manufacturers and brands comprises brand labels and manufacturers of both original equipment manufacturer (OEM) and after-market products generally related to in-car entertainment that already have articles within Wikipedia. While components sold by these companies have much in common with other audio applications or may ...
Certain Lexus models have featured Mark Levinson sound systems as an option since 2001, [4] [6] with prices varying based on the vehicle and its specific components (~US$2,500 for the LS 460, ~US$1,600 for the ES 350, ~US$1,440 for the IS 350, etc.). The first Mark Levinson car 5.1 surround sound system appeared on the Toyota Crown Majesta in ...
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
