Electric and hybrid vehicles could reduce noise pollution, but only if those vehicles make up a high proportion of total vehicles on the road; even if traffic in an urban area reached a makeup of fifty percent electric vehicles, the overall noise reduction achieved would only be a few decibels and would be barely noticeable.

Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.
What you can do to limit your exposure to noise pollution All three experts agree that noise pollution is a problem best addressed at the societal level rather than being up to individuals.
Noise control is a set of strategies to reduce noise pollution by reducing noise at its source, by inhibiting sound propagation using noise barriers or similar, or by the use of ear protection (earmuffs or earplugs).

This noise, however, has been shown to be harmless to animals, except for horses who will become skittish. [30] Railway cargo can be a cause of pollution. [30] Air pollution can occur from boxcars carrying materials such as iron ore, coal, soil, or aggregates and exposing these materials to
The signals are processed to cancel the noise from the desired signal, producing improved voice sound quality. In some cases, noise can be controlled by employing active vibration control. This approach is appropriate when the vibration of a structure produces unwanted noise by coupling the vibration into the surrounding air or water.
