As diesel engines and other equipment can get extremely noisy that it can affect the ears of those who work or are living nearby, the need for acoustic containers has aroused. That is why the Noise Control Regulations for Work were adopted in 2005. This rule is aimed at ensuring that the noise at those thresholds is filtered, so as not to induce hearing damage or tinnitus to those in or around the building.
Silent & Sound Proof Containers
The need for silent generators has increased in time. While the acceptable noise level was 80 dB(A) in the past, nowadays the standards have changed and 60-70 dB(A) is considered acceptable. The change in these standards led to the development of more complex and professional soundproof containers.
Generators may be enclosed in a container or enclosure where possible. Besides, a soundproof ‘refuge’ can be built if the machine is located in a position where noise does not cause problems for neighbors to isolate employees from the noisy exterior.
We provide a standard range of acoustic diesel generator containers between 10 kva and 2000 kva. Our containers are available for various generators with different requirements, specifically designed to use with diesel generators. Completely demountable options are available if there is a space limitation.
How Does a Sound Proof Container Work?
Soundproof containers utilize composite materials to reflect the sound energy created by the generator back inside. This is generally done using hard materials, however, soft and porous materials can also be used to absorb sound energy and convert it into heat energy.
Soundproof containers, also known as sound Attenuated containers, use different types of materials for different frequencies because some materials are simply not good enough to absorb the sound energy.
In general, when the sound coming from the source reaches the walls of a room or a container, some of the energy is reflected, while some are absorbed and some are transmitted to the other side. Acoustic energy is transmitted in a material, i.e. brick walls, in the same manner, that it is transmitted in the air which is called pressure differentials or deformations. This deformation actually causes mechanical losses, which leads to acoustic attenuation by the conversion of sound energy into thermal energy. The viscosity of the material plays a great role in this conversion.
Soundproofed containers are typically made of steel and filled with acoustic absorbents. Such materials may be in several layers as different sound frequencies are absorbed by various materials. Included specifically for higher frequencies are one or two layers. Lower frequencies pose a particular challenge to ensure that the entire spectrum of sounds is completely absorbed and transmitted and involves a specific material and structure.
How Much Noise Reduction is Possible with a Sound Proof Container?
The soundproofing level of a soundproof container may vary depending on the manufacturing company. Standard containers may provide between 30 to 40 dB(A) noise reduction. A 40 dB(A) reduction in noise means 4 times less noise. Reducing your generator’s noise level to a point below 80 dB(A) should be aimed to provide a healthier working environment for your workers.
- Manufactured by steel sheets to ensure corrosion resistance.
- Re-treated and pretested components for a longer lifespan.
- High-quality neoprene gaskets used indoors to prevent sound leakage.
- Increased airflow with low emission thanks to hoods and ducting.
