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.
The underside of a vehicle often traps air in various places and adds turbulence around the vehicle. In most racing vehicles this is eliminated by covering the entire underside of the vehicle in what is called an under tray. This tray prevents any air from becoming trapped under the vehicle and reduces drag. [12]
The 7 post shaker is used for many vehicles in different driving conditions. Earlier versions were the 5 post shaker and the 4 post shaker. The 4 post shaker is commonly used by vehicle manufacturers to investigate squeaks and rattles.
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Residents of each community have expressed similar concerns about the noise and rattling in social media posts and news reports. In 2024, SpaceX conducted 46 Falcon 9 launches from Vandenberg.
Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
The car avoided the sporting ban by claims that the fan's main purpose was for engine cooling, as less than 50% of the airflow was used to create a depression under the car. It raced just once, with Niki Lauda winning at the 1978 Swedish Grand Prix. The car's advantage was proven after the track became oily.
In-car entertainment (ICE), or in-vehicle infotainment (IVI), is a collection of hardware and software in automobiles that provides audio or video entertainment. In car entertainment originated with car audio systems that consisted of radios and cassette or CD players, and now includes automotive navigation systems , video players, USB and ...
