An acoustic enclosure came in as a result of the increase in the usage of huge machinery such as generators, diesel generator sets, gas compression sets, transformers, etc. Many of these devices work at extremely high noise speeds, which can only make your hearing noisy but also harm your ears. How do we fight those large amounts of noise? How will the well-being of the workers employed in and around the facilities be ensured? There’s a way to do it.
Acoustic enclosure:
Acoustic solution specially built for controlling noise emissions by muffling high levels of noise produced from large machinery such as DG Sets.
We need a greater knowledge of the sounds, the various levels of noise, and noise analysis to better decide on the purchase of a noise reduction device such as an acoustic enclosure until we realize if the enclosures are performing better.
Noise and estimation levels:
The Sound is what we perceive, and is seen as a mechanical wave caused by the acceleration of the particles in the material when the wave passes into the medium. The sound frequency is calculated in the DB scale.
The noise of the generator can be seen from 2 sources:
- Mechanical noise from the mechanical vibration of the machine’s many moving parts and modules. Smaller motors and lower cylinders make their size more noise and vibration.
- Combustion noise from the motor. This might involve exhaust noise, fan noise, induction noise and alternator noise caused by the combustion phase from the engine.
Acoustic generator function:
Acoustic boxes are acoustic chambers that mitigate or alleviate noise from massive appliances. They are engineered to muffle noise to an appropriate degree of tone. The acoustic material used for the enclosures performs sound isolation and absorption roles.
Advantages of acoustic enclosures:
- Noise reduction will increase efficiency for workers
- Custom noise control- Boxes may be built to preserve the required amount of sound in a healthy working setting.
- The modular structure of acoustic enclosures makes it possible to add aids that comply with government noise reduction regulations.
- Low maintenance – While the boxes are large, maintenance due to the non-moving sections of the box is limited.
The various components used in acoustic boxes:
- Isolation/Acoustic Isolation – Indoor sound absorption is used to block sound to keep it from getting outside.
- Acoustic Barriers / Partitions – Steel panels are used to contain the acoustic engineering equipment
- Acoustic louver and attenuators – These are used to facilitate airflow when attenuating different levels of noise. Attenuators are intended to minimize noise on the airway.
- Isolation mounts/pads – Enclosures are placed on concrete pads or insulators to discourage sound waves from moving across air and land.
- Wetter-resistant enclosures – It is highly sturdy and can be used through summer, rainy season and winter in harsh weather conditions.
Acoustic Doors–
- For manual access in the enclosures for simple maintenance of machinery.
- For easy maintenance.
The High Machines Acoustic boxes are made of an exterior steel frame. The enclosure walls are isolated with fireproof acoustic insulation. Each box comes with a window with panel views and side doors. Attenuators are built to fulfill efficiency requirements and reviewed.
Conclusion: An attenuator is a system that requires vast quantities of air to flow through it but reduces noise propagation. Air is pushed between splitters (perforated Rockwall-based sheeting) that absorb the sound and decrease the wavelength. This enables them to operate even in the toughest setting, thus preserving specified noise levels without power loss.
