Low-frequency acoustic fencing works by creating irregularities in the air that creates an "interference" with external noise. You've probably seen these systems in use at places like airports and train stations. They're essentially giant speakers that produce localized sound. While these systems don't reduce background noise to a significant degree, they do provide a pleasant background sound that some people find uncomfortable.
The main disadvantage of this type of acoustic fencing is the amount of noise it creates. The basic design relies on three frequencies - low, high, and medium. This creates a rather large "loudness range". A larger range means louder sounds can be heard from further away and some sources of noise can be amplified.
Many businesses and homeowners with acoustic fences choose to purchase a separate piece of equipment to help with the problem. These devices are often called a noise control diffuser. They're used to reduce the overall level of noise, although many experts don't agree that the term 'diffuser' is actually the correct term. Some experts call them "over-driver units". The way to describe them is this: An additional outside electronic device that automatically increases the strength of the acoustic fence's air barriers when a current is applied.
Some diffusers have filtering elements built in to prevent sound from traveling through them and some have what is referred to as a "bounce back" mechanism. The bounce back mechanism will basically push back against any noise that is created by the diffuser and send it back out into the surrounding area. This effectively resets the signal, so the source of the sound has to emit louder to get through. In essence, it makes the original sound smaller.
Some acoustic fence manufacturers sell automatic diffusers. If you're looking for an easy to install fence that doesn't require complicated wiring or drilling, this may be the right option for you. However, most companies that sell these diffusers also sell other types of fence systems. https://darhan.pl/2021/05/21/ogrodzenia-plastikowe/ might be to compare the diffusers that they sell to the various systems offered by your competitors. You'll likely find that if you buy diffusers from a company that sells a broader range of products, you're getting a better deal.
There are a number of considerations to make when choosing diffusers for acoustic fence systems. Make sure that they're designed to reduce the noise that's created by wind, not just from particular sources. It's also important to check that the diffusers actually work as advertised. Most people installing diffusers at their own homes will have little experience in this area, but it's something that you should definitely take the time to research before you go ahead and purchase the first one you see. Many companies that sell acoustic fence systems will offer a free consultation so you can learn more about the products before you buy.
Acoustic fencing can protect you and your family from a lot of unwanted noise. However, there are times when it's not working as well as it should. If you've noticed that the sound of wind is louder over your fence, or that the noise from barking dogs is more intense at certain times of the day, then you may need to use an acoustic fence noise reduction system. Noise reduction is easier than ever with the technology available today. Learn more about diffusers for acoustic fence systems today.
