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 ...
I was impressed by the QX60's sleek design, quiet ride, and well-designed cabin. Unfortunately, the QX60 is let down by its unrefined turbocharged, four-cylinder engine, dated infotainment system ...
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 ...
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 ...
The same system may also be used to synthesize or augment engine noise to make the engine sound more powerful to the driver. [33] 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 day after the crash, the single-engine airplane remained at the site as investigators with the National Transportation Safety Board returned to the area to try to determine why it went down just ...
