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.
Commercial applications of 3-D noise reduction include the protection of aircraft cabins and car interiors, but in these situations, protection is mainly limited to the cancellation of repetitive (or periodic) noise such as engine-, propeller- or rotor-induced noise. This is because an engine's cyclic nature makes analysis and noise ...
Ford has gotten about 100 complaints from F-150 truck owners who say the speakers in their vehicles are emitting a loud, annoying noise that sounds like static, or glass shattering, and which ...
The 2011 Nissan Leaf was the first electric car equipped with Nissan's Vehicle Sound for Pedestrians called 'Canto'.. Electric vehicle warning sounds are sounds designed to alert pedestrians to the presence of electric drive vehicles such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs) travelling at low speeds.
Using a combination of sound absorption materials, arrays of microphones and speakers, and a digital processor, a restaurant operator can use a tablet computer to selectively control noise levels at different places in the restaurant: the microphone arrays pick up sound and send it to the digital processor, which controls the speakers to output ...

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 ...
