Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations, or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather ...
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 ...
Screen size varies from 5-inch to 7-inch for the double Din car stereos. Active noise control and noise synthesis. The automobile sound system may be part of an active noise control system which reduces engine and road noise for the driver and passengers.
Active sound design is an acoustic technology concept used in automotive vehicles to alter or enhance the sound inside and outside of the vehicle. Active sound design (ASD) often uses active noise control and acoustic enhancement techniques to achieve a synthesized vehicle sound. The typical implementations of ASD vary, from amplifying or ...
The Act established mechanisms of setting emission standards ( noise regulation) for virtually every source of noise, including motor vehicles, aircraft, certain types of HVAC (heating, ventilation, and air-conditioning) equipment and major appliances. It also put local governments on notice as to their responsibilities in land-use planning to ...
Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing .
Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government. After the watershed passage of the United States Noise Control Act of 1972, [1] other local and state governments passed further regulations. A noise regulation [citation needed ...
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.
