Reducing Demolition Noise: Acoustic Barriers and More

The noise and dust generated by demolition sites could disturb the lives of nearby residents. But, there are solutions to reduce the nuisances to ensure that the workers and residents can have a the comfort of their workplace.

Filtering particles and pollutants inhaled, LEVs can help reduce noise pollution. (LEVs) will help to reduce the noise generated during demolition and masonry works.

Sound Control to Demolish

Demolition is loud and noisy, however there are options to limit noise levels to reduce the effects on surrounding neighbors. The use of daylight hours during work and the restriction of noise-producing equipment to certain hours will assist in decreasing sound.

Informing residents about the timetable of demolishment can let them be aware in advance about what is to be expected. Furthermore, selecting the right contractor with a positive record of compliance can reduce chances of complaints. Additionally, using equipment that is quieter can drastically reduce the amount of noise created when demolition. Obayashi’s Bubble Silencer for instance can cover the chisel in massive breakers (heavy machineries that crush cement) using bubbles to cut down on the noise. It can reduce noise by up to 5 dBA and removes up to 90% of the dust that is generated during demolition.

Dust suppression in Demolition

Dust removal is an essential aspect of demolition as dust can be contaminated with hazardous substances including asbestos, aluminium and crystallized silica. They pose danger to both the workers and nearby residents.

Before work starts an area for demolition is washed thoroughly in order to stop dust becoming suspended in air. It’s a good method however, it does require a considerable amount of effort in order to move the hoses and to constantly move them.

Others, for instance making use of a misting gun to catch dust can be more effective and safe for workers. For instance, a device such as the Bubble Silencer can cover a breaking device and decrease sound by five decibels with bubbles. It also helps protect workers’ health.

Acoustic Barriers to Demolition

Noise barriers block sound waves, which helps minimize noise from demolitions. They work best located near the source of noise or the vicinity of a sound source.

Other strategies to minimize the noise are to use equipment that has the ability to reduce noise. Another option is scheduling work during times when people are not around. Also, it’s important to periodically evaluate the noise level and make adjustments if necessary.

Using hydrodemolition equipment, such as the one above, could significantly decrease dust and noise in concrete demolition. Hammers that use it don’t need to strike as hard at the concrete as they do using traditional breakers, which makes them much quieter.

Dust Control in Construction

Dust is a natural but challenging by-product of construction projects, especially during the drier months. Dust causes irritation to those working in the construction site, but could pose health hazards. Inhaling dust frequently may lead to respiratory problems and even deaths. If dust gets airborne, it can be harmful to biodiversity and wildlife.

To keep construction dust to a minimum Teams may use a variety of control measures. These can be broadly categorized as administrative controls and personal protection equipment (PPE).

Controls to control engineering use sprays of water that can reduce dust or installing local exhaust ventilation systems in machinery. Administrative controls could involve altering plans for work, as well as limiting duration and frequency of activities that generate high levels of dust. PPE is the last line protection against dust. It includes respiratory protection and eyewear.

Demolition Site Pollution Management

While demolitions generate a lot of noise and dust it is important to minimize the impact on people living nearby in the interest of complying to environmental law. By using a relocatable monitor with a dust and noise sensor, pha do nha xuong cu hcm you will be able to continuously measure air quality and adjust the working area to reduce pollutant emissions.

Also, it is important to choose contractors who have demonstrated expertise in working on similar projects. It will reduce the chances that your neighbor will be complaining.

Current research shows that environmental pollutants on demolition sites are often not tracked, which means they can’t be measured in real time. The latest IMS examines air pollution, noise, and vibrations in demolition sites, to ensure they’re in line with government regulations.
