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.

A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
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). [20] Control at the source is the most cost-effective way of providing noise control.
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.
Six of the top ten noisiest cities in the U.S. are located on the East coast. Louisville ranks among the top 50 loudest places in the country.
Sound baffles on the wall of a recording studio. A sound baffle is a construction or device which reduces the strength (level) of airborne sound.Sound baffles are a fundamental tool of noise mitigation, the practice of minimizing noise pollution or reverberation.
Marie Kondo, the decluttering expert famed for helping people clean up their living spaces, has admitted that there is an “impossible standard” of maintaining a tidy home.
Noise Free America is a national, non-profit organization aimed at reducing noise pollution in the community. The organization's main target is noise from boom cars (vehicles with loud sound systems), leaf blowers, motorcycles, and car alarms. [1] Noise Free America has a 501(c)(3) non-profit status and has chapters in 27 states across the U.S ...
