The noise and dust generated by demolition sites can disrupt neighbors. However, there are many effective ways to manage this issue so that residents and workers can enjoy an enjoyable working space.
Local exhaust ventilation (LEV) systems are able to reduce noise from demolition and masonry works by filtering dust and other pollutants that are breathed in.
Sound Control in Demolition
There are a variety of ways to reduce the noise and disruptions created by demolition projects. In particular work during the day and limiting use of loud equipment to specified times can help avoid nuisance.
Similar to announcing the date of demolition to the local population can let residents know ahead of time the time when they can expect disruptions. Furthermore, selecting a contractor with a good record of compliance can reduce the possibility of complaints. Also, employing quieter equipment can drastically reduce the volume of sound produced by demolition. In the case of Obayashi’s Bubble Silencer covers the chisel of giant breakers (heavy equipment that crushes concrete) with bubbles in order to block the noise and minimize dust. The gadget reduces noise of up to 5 dBA and removes up to 90% of dust created during demolition.
Dust suppression in demolition
Dust suppression is a crucial element of demolition since dust particles could contain dangerous substance like asbestos aluminum, and crystalline silica. These substances pose a risk to workers as well as nearby residents.
Prior to the start of work an area for demolition is thoroughly drained to prevent dust from being in the air. This is a very effective technique but it takes a substantial quantity of labour to move hoses and constantly reposition them.
There are some solutions that are safe and better than others, such as employing a spray gun for example, to gather dust. Bubble Silencers may cut down the sound of breakers by as much as 5 decibels. This can be beneficial for the health of workers.
Acoustic Barriers during Demolition
Noise barriers absorb or block sounds, helping to minimize noise from demolitions. They work best at being placed close to the source of noise or within an area that is sensitive.
It is also possible to reduce pollution by using equipment to reduce noise and planning work for time periods that are peaceful. Additionally, it is important to regularly monitor the noise level and adjust as needed.
Using hydrodemolition equipment, for instance, can dramatically reduce noise and dust during concrete demolition. Hammers that use it don’t need to strike hard against concrete, as they do using traditional breakers, which makes them quieter.
Dust Control for Construction
Construction sites are always filled with dust. This can cause problems when the weather is dry. Dust causes irritation to the workers involved, it may pose health threats. Dust inhalation can result in respiratory ailments and even dying. If dust gets airborne, it is harmful to biodiversity and wildlife.
Teams can use a number ways to reduce dust during construction. They are classified as administrative controls and personal protection apparatus (PPE).
Engineering controls include the use of sprays of water for dust suppression or installation of exhaust vents local to equipment. Administrative controls may include altering the work schedule and limiting those activities that are high in dust length and frequency. The final defence against dust is PPE, which includes eyewear and respiratory protection.

When demolitions create a lot of dust and sound, it’s crucial to limit the impact on people living nearby in order to comply with environmental laws. By using a relocatable monitor with a dust and noise sensor, you will be able to continuously assess the air quality and then alter the environment on site to reduce pollution.
It’s also essential to work with a contractor who has demonstrated prior experience with similar projects. This can reduce the chance of complaining from neighbors.
The research shows that a lot of environmental pollutants are not measured in demolition areas, meaning they can’t be evaluated in real-time. The latest IMS is specifically designed to track both sound and air pollutions in demolition sites in order to make sure that they are in compliance with the regulations.
