Different types of corporations and industrial factories use a lot of noise control equipment. It is required to control noise pollution and thus maintain a calm and serene environment. There are a wide variety of noise sources which are classified as internal and external.

Both the internal and external noise components should be eliminated completely for safety reasons. The internal noise which comes from machines and equipment can cause harm to the working staff. Also, the external noise pollution can cause harm and chaos in the surrounding environment.

Here are 6 ways to control industrial noise:

 1. Ventilated Canopies and Enclosures

The main goal of industrial noise control is to minimize the noise and reverberations coming from machines and equipment. So, to prevent these reverberations, ventilated canopies and enclosures are used. There is numerous equipment that can create substantial level of noise. This equipment includes generators, pumps, chiller systems, and compressors and many more.

So, to prevent such type of equipment noise, you need to enclose them in some sort of enclosure. For this purpose, acoustic doors, enclosures or boxes are used. Moreover, these acoustic ventilation systems do not impact the performance of these equipment. These enclosures have ventilated openings so that all sorts of heating are prevented. Also, you can remove these acoustic panels and hatches, if you need to perform maintenance work.

 

2. Sound Absorption Panels

The main problem with industrial equipment is that their sound produces an echo. Now, this echo, produces a reverberation (time taken for the echo to fade off). So, to solve these reverberation problems, we often use sound absorption panels.

These panels reduce reverberations to a greater extent and thus providing an acoustically softer environment for staff and employees. So, to reduce these echoes, these acoustic panels are either hung from ceilings or used as surrounding walls.

3. Acoustic Barriers

You should use high quality acoustic barriers even on the outside. These barriers will help prevent the external factors of noise. Moreover, these barriers are extremely successful in a variety of industries such as transportation, mechanical and manufacturing plants, and athletic venues.

Once placed in a correct manner, these acoustic panels can be extremely long lasting. Moreover, they even add an aesthetic value to the environment and even act as a canopy for the surrounding environment. IAC provides three major acoustic barrier options. They are: absorptive free-standing barriers, reflective cladding panels, and louvred screens.

4. Absorptive Free-Standing Panels

Absorptive free-standing panels can limit sound transmission. Moreover, they are lighter and are pretty easier to install than standard concrete barriers. Also, these absorptive panels are very efficient and lower to maintain. Moreover, these panels are pretty easy to maintain and they also last longer.

Also, aluminum acoustic panels have a high wind-resistance are don not catch rust that easily. Moreover, they have a high co-efficient of sound absorption. Hence, they can easily damp external noises from the industries.

5. Acoustic Cladding Panels

Acoustic cladding panels are of great help. They can improve the noise-absorption potential of existing acoustic barriers to a great extent. Because of this reason, they have a great deal of flexibility and applications, as well as a relatively straightforward installation process. There are many laboratory-tested acoustic barrier systems that have a certified sound transmission loss rate. They are available in a variety of sizes.

 

6. Louvred Screens

Louvred screens are extensively used in plant and chiller complexes to reduce noise and echo. It allows air passage through the barrier for cooling or exhaust reasons. Louvre screens with slanted apertures deflect and disperse noise away from sensitive areas.

Also, while doing so, they enable air to flow freely into required areas to maintain the cooling or ventilation systems’ function. You can customize a louvre screen in various size and shapes. Additionally, it may blend in and be an appealing addition to a space while providing exceptional noise reduction.

Acoustic barriers are useful for noise control applications at ground level, on roads, rails, bridges, and rooftops, among other places. Noise barriers shield communities from the intrusive noise created by highways, railroads, and airports, among other sources.

Why Industrial Noise is dangerous for workers?

Excessive industrial noise can cause hearing damage. It can also induce severe physical and emotional stress factors, such as headaches.

Moreover, these signs and symptoms might include exhaustion, anger, temporarily high blood pressure, and hearing loss. Repeated exposure to high noise for a long-term can induce hearing loss (a permanent condition) and even permanent hearing disorder. It is also uncertain if these exposures might contribute to more long-lasting cardiovascular disorders, such as high blood pressure.

Apart from hearing loss, researchers have found out that a high amount of noise can even lead to other ailments. It includes high blood pressure, high cholesterol, and heart disease. Recent findings from a new NIOSH study, titled “Cardiovascular Conditions, Hearing Difficulty, and Occupational Noise Exposure within U.S. Industries and Occupations,” investigated the relationship between loud noise at work and conditions such as high blood pressure and high cholesterol. According to the findings of this study:

  • 58% of workers will have reduced hearing problems if the noise levels were at the safe levels.
  • Excessive noise at work may increase the risk of high cholesterol and blood pressure.

Factory noise control should be the primary goal of almost every other factory. Because it can lead to several diseases both in the short and the long term. There are many modern methods to control industrial noise which when implemented creates a significant difference in the noise levels.

So, factories should be concerned about lowering their noise decibel levels. This will surely help improve the environment and the atmosphere.
