Noise is a common subject of complaint in Hong Kong and reducing it has been a priority for the EPD since the department was established in 1986. Controls are imposed on construction noise, noise from commercial and industrial premises and neighbourhood noise, and much effort has gone into preventing noise.

Noise pollution is excessive amounts of noise from a wide range of sources in cities. These include aircraft, trains, automobiles, motorcycles, construction equipment, home appliances, loud music, nightlife, and even barking dogs. Transport, machines, and propagation systems are the main causes of outdoor noise globally. When exposed to noise pollu...
1. Ride electric vehicles
One of the ways to reduce noise pollution on roads is by using electric vehicles, such as electric cars, electric scooters, and electric buses. These vehicles do not contain an engine, which makes them a quiet alternative to traditional vehicles. Besides this, electric vehicles don’t need to use fuel, so it doesn’t emit any harmful gases into the atmosphere. These are not only noise-free vehicles but also eco-friendly and sustainable ways to travel. Invest in electric cars, use electric scoot...
2. Lubricate machines frequently
Whether it’s a car, scooter or construction machine, lubricating machine parts will not only maintain the machine but also reduce the noise from its moving parts. After all, lubricants prevent the moving parts from rubbing against each other, creating noise, and breaking down. This is especially helpful for construction work since it creates one of the loudest noises in cities. Equipment operators should frequently inspect their machinery and lubricate them regularly or as needed.
3. Replace old vehicles
One significant source of noise pollution in cities is old vehicles. Because of the old engine and moving parts, it creates more noise than new vehicles. Lubricants may somehow lessen the noise, but ultimately, it is already the engine itself that causes the noise. Sometimes, old vehicles can even create deafening sounds. Replacing old vehicles with new ones will lessen noise pollution and lower soot emissions in cities.
Although the hustle and bustle make cities what they are, people don’t need to live in a noisy environment all the time. Moreover, notice how lessening noise can also help reduce energy consumption and air pollution. Reducing noise pollution will not only affect people but also the environment.

- Why is Noise a Problem?As Hong Kong's economy has grown in recent decades, so too has the noise that comes from construction, commercial and industrial sources, and transport in this compact, densely populated city.
- Construction and Renovation Noise。Hong Kong is renowned for its city skyline, which is the result of a very active construction industry.
- Neighbourhood Noise。Neighbourhood noise from domestic premises and public places is restricted under the Noise Control Ordinance.
- Traffic Noise。The Government has made continual efforts in minimising existing traffic noise through providing professional advice to various Government departments on the design of new roads and nearby buildings, as well as retrofitting roadside barriers and resurfacing existing roads with low-noise materials.
2015年11月8日 · Solutions to noise pollution in communities include the installation of low-noise road surfaces, maintaining existing roads, building low-noise train tracks, railway and train depots, the installation of noise screens adjacent to highways and other noisy areas
According to the National Park Service (NPS) in the United States, noise pollution has an enormous environmental impact and does serious damage to wildlife. Experts say noise pollution can interfere with breeding cycles and rearing and is even hastening the extinction of some species.
2023年1月17日 · These solutions include using green architecture, such as soundproofing, sound barriers, and sound masking. Where soundproofing attempts to reduce the amount of sound that escapes from a given space, sound barriers are physical structures that stop sound from traveling.
