Mystics of Acoustics

Factory sites and industrial locations are often marked and clubbed up with places classified as a heavy noise pollution zone, not precisely the workspace you wish to be in. Being in such an environment can have severe damage to the acoustic membranes of your ears, and sometimes, if the noise is deafening, going over specific decibels can even be the cause of rupturing your ear walls or having permanent damage to the eardrums,

Many such accidents still occur daily at such sites and work with many noise discrepancies and loud heavy vibrations caused by the sound waves. All in all, it’s a slow, noisy trap that would indeed claim your ears if left as it is. In some severe cases, people with a heart problem also face fatal problems due to loud noise, causing sound waves to affect and hamper hearts with their pressure. As a result, it raised a higher degree of concern with the increasing casualties and even fatalities among the employees, which also slowed down the workflow. Hence, ways to minimize this and attempts were made to tackle issues regarding factory noise control.

To Overcome This Difficulty, Two Private Industrial Measures Can Be Taken Into Consideration,


To minimize the factory noise control, a provision was made to add a sound absorption mechanism in the building design. Applying the acoustic enclosure principle focuses on reducing the reverberations and the surrounding noise, inside and outside the factory, to create a noise-free surrounding. If you take aids and advice from an acoustic expert, they would advise you to construct the lower half of your building walls to get the phenomenon rolling. This structure would help lower the factory noise control at a lower level with low-frequency levels while also being robust to be still durable enough to tackle the daily wear and tear faced due to being a factory wall.


A channeled, ridged ceiling is supposed to be treated with this product. This made the ceiling walls very efficient in absorbing all the sound which was directed towards it; the layer of the coat also turned out to be an excellent reflector of light which makes its use not only helpful in factory noise control but also to illuminate the room into a brighter version of itself. Apart from the science and usefulness, it also proves to be an aesthetic color spray-painted on the factory walls, which would seem dirt otherwise with all the dust and dirt which appears invisible on the paint, making the room perfect acoustic enclosures indeed.

Conveying The Issue

A factory room comprising of floors, walls, and complex roofs would be a giant echo chamber with sound waves and noise reverberating in the entire room because of the absence of acoustic enclosure or any makeup treatment. You would be shocked to know the number of songs produced when the machinery noise reflects off rigid walls and roofs, which returns reflects in the entire premises to create a substantial amount of echo and noise pollution, increasing the noise levels from within. On the outside, it is still a pressing issue as excessing noise escaping out can still attract the authorities’ attention.

Hence, to avoid such kinds of issues, HSE requirements were set up for safety purposes. Every building had to follow these norms to lessen the noise pollution caused due to such facilities because, on the other hand, if workers were asked to wear noise cancellation devices and such equipment, there would be times when they won’t be able to hear instructions given at a mass level or the sounds of machinery which could in return increase risks of mishaps and accidents. The straightforward answer to factory noise and control is to design your factory walls and roofs specifically and install expensive machinery specializing in acoustic enclosures, which may have other utilities and benefits like having forced ventilation to prevent the equipment from overheating. But all these techniques would only ensure that the noise is enclosed instead of adequately addressing the fundamental problem, which is the excess noise.

But, by having specific equipment as mentioned above, you can provide insulation to your factory in addition to achieving economic noise control. This guarantees a minimum disruption of the workflow and creates a safer environment for your workers and employees.

A Closer Look at The Enclosures

Depending on the machinery, size, structure, and noise it makes, there can be applications of the different enclosure types.

Complete Enclosure.

As the name suggests, this section corresponds to one where the entire machinery is enveloped from every side. The employees are to enter the enclosed space whenever required to carry out the equipment they are supposed to perform.

Integrated Enclosure.

In this type, the section is adjacent to the machinery, and the operators aren’t supposed to enter inside. For example, about 35 dB of noise reduction can favorably be achieved by an integrated acoustic enclosure around a metal press. Apart from noise reduction, this chamber also provides a ventilation system for the machine to ensure overheating and air-conditioning. This is a custom-made enclosure.

Partial Enclosure.

Like it is referred to as, in a partial enclosure, the upper roof or ceiling is not isolated acoustically, meaning it can be called incomplete enclosure. This includes a lighting system LED-based and also a silencer for the air inlet.

Noise has always been stated as a hazardous phenomenon that can dampen your physical and psychological abilities! The main culprit behind it being the stress causing it exhibits and abuses over a wide range of areas and jeopardizing the entire workforce. Exposure to such dangers with uncontrolled measures can cause acoustic trauma or even permanent loss of hearing. Hence, the issue of noise control at your factory or your workplace is one of the most critical issues that need to be taken care of right away to avoid and prevent needless casualties and have your employees work in a well-sustained and controlled environment.
