Many of our customers have some mechanical equipment next to the building, which has caused some noise complaints. Is there an easier and affordable solution?
solution
Due to the number of variables involved and the fact that the product must be used outdoors, external acoustics and noise reduction may be a bit unstable, but there are best ways to solve these problems.
When the machine is running outside the building, something happens. Obviously, the machine will produce a kind of sound/noise, which spreads from the machine to potential listeners in a relatively straight line. At the same time, the sound from the rear (or side of the building) of the machine is quickly reflected from the hard surface that forms the outer wall of the building. Reducing reflections can sometimes reduce the problem to an acceptable level, but usually some kind of wall or fence is required.
Machine noise-after acoustic treatment
As I mentioned above, due to the many variables involved, external acoustics may be more complicated than sound processing inside buildings. In this case, this machine is harassing people in neighboring areas. A barbed wire fence has been installed around the machine to ensure the safety of the machine, which is good because we need the structure around the machine to support the product.
The external sound insulation blanket is the most successful product I have used for many years. It is the external sound insulation blanket. It is very much like a U.V. stabilized glass fiber absorber, stitched to a 1 pound per square foot vinyl. Imagine a moving blanket sewn to a piece of lead, and you will understand. These are custom panels with a row of grommets for mounting the panel to the fence, usually vertical external grade velcro seams to connect one panel to the next panel. They are customized for each job to fit the relevant fence or structure. They are very effective acoustically and will last for years-even if they are used in the most extreme environments. One thing to consider is that these blankets will basically act as sails, and they may not be the right choice in high wind or unsupported installation types.
For the curtain absorber with external padded cushions I mentioned earlier, another option is to reduce the sound pressure generated by building echo, which can sometimes provide enough performance to get you where you need it. This is usually done through the EFT-QFA panel. The size and position of these panels should be considered according to each job, so please feel free to contact me with the following details, we can discuss in detail. These panels are only the absorbent part of the aforementioned curtain panels. Since the building is already a better barrier than 1lb vinyl, no barrier part is needed.
The new product of Echo Barrier Temporary Noise Barrier is the Echo Barrier Panel. This is a stock, externally rated sound panel, prefabricated to be ~6.5′×4.5′. When the panels are installed on the panels, they are overlapped instead of being connected to each other using Velcro. A good choice for these panels is that they can be rented or leased. This allows customers or end users to lease them for a period of time instead of buying them exclusively. If the noise reduction effect is satisfactory, the lease can be bought out, or the lease expires, and then the panel can be returned.
