Keep Rural Properties Safe by Installing Flood Barriers

If you live in the countryside, you will already know about the many benefits of not residing in a large town or a busy city. There has been something of a stampede on our rural communities in recent years, purely because so many men and women have decided that they have had enough of the urban existence. Life for them is now so much more tranquil.

It goes without saying that for many people living in the city represents the ideal scenario. They like to be close to their work, they enjoy the vibrant social scene and the fact that they can get from A to B with relative ease thanks to a complex public transport network. For others, life has to be lived in the countryside, even if it means having to invest in flood barriers to protect property.

We are all individuals, of course, and as such we each have our own views on what’s good and what isn’t. If a slower pace of life is something you fantasise about, it may be time to start looking at property websites which focus on flats and houses which are located in some of our more peaceful villages and hamlets.

Live Where You Want thanks to Acoustic Barriers

If you ever thought it might be difficult to live close to a main road, the chances are you will have underestimated the awesome power of acoustic barriers. These incredible assets make like worth living in areas all over the UK, thanks to the way they absorb the sound of constant traffic. Even beside some of the busiest roads in the country, you will find far lower decibel levels. Buying a property in such an area should never be a no-no because of noise pollution.

People who live close to major roads are able to enjoy a high quality of life despite the cars, vans and trucks which pass close by. We all like to spend some quality time with family members and friends in the garden when the weather is warm, and we can do just that thanks to noise barriers. These scientific marvels are able to deaden the sound of traffic with ease, so we can all lead happier lives without having to worry about the din.

Thanks to the provision of acoustic barriers, thousands of home buyers are able to forget their initial reluctance about purchasing a property close to an airport or a main road. Such areas may have previously been out of bounds, but that’s no longer the case now.

Racetracks and Noise Reduction

Acoustic fencing for racetracks is an expensive business.  Simply surrounding a track could break the bank for many track owners, which is why the investment in noise map technology is so important.

The maps are really useful for highlighting where the sound is a problem, and also less of a problem, e.g. much of the track may be surrounded by uninhabited farmland, which would identify sections where fencing may not be required at all.  The analysis can also highlight situations that generate excessive noise that can only ever be detected by continuous monitoring, and other places where sound levels never exceed limits and so do not need any acoustic barriers either.

Acoustic Fencing and Noise Mapping

New technology has allowed the development of a type of computer modelling called Noise Mapping.  It consists of a series of microphones placed around the track and outside the perimeter to monitor noise levels, and how they vary, throughout a race.  The microphones are all linked through a computer server to sophisticated software that creates a colour coded map of the track and the surrounding area to highlight the hot spots and regions that suffer the most from noise pollution.  The data is also collected over time, which can make a considerable difference to the expected results. A person standing at various points of the track throughout a practice session or a race might draw conclusions as to where acoustic fencing would be most appropriate, but because the map is built up over time the results can be quite enlightening.  Areas that may have been thought the most problematic, such as the start line or the area around the Grandstand, may actually show up as being only short term noise pollution points.  Other areas away at the back of the track that may have features, such as tight bends followed by long straights, that lead cars and bikes to change gears and rev hard.  So while spectators and track staff may not be aware of the noise pollution, local residents may be all too aware of irritating noise levels.

Acoustic Barriers From Sonic Crystals

Acoustic barriers are changing, and it's all down to the development of materials known as Meta Materials.  These are substances that don't exist in nature, and have been made in labs and factories to have specific properties.  They tend to be strong, light, and have a very regular structure.  Their application to acoustic barrier technology is this combination or properties.

  Sonic crystals, in terms of acoustic barriers, are in fact an array of circular cylinders that have been spaced such a way that any sound entering the barrier is bounced around within the array, dissipating as it goes, The name sonic crystal comes from the way deals with sound energy in a similar way to what photonic crystals do with light.

The spacing of the cylinders depends in an array depends on:

the dimensions of the cylinders, and,

the frequencies of the sound that need to be prevented from passing through the acoustic barrier. 

In effect, the sound waves are captured within the array of cylinders and absorbed, rather than passing through reflected back as with more standard acoustic fencing.  So it is as much the space between the cylinders as the cylinders themselves that make sonic crystals so effective.

The only real draw back to the sonic crystal design approach is they are difficult to standardise.  To work best, the spaces between the cylinders has to be right for each particular application to match the causes of sound in that area.  An array that works really well beside a  road might be wholly ineffective outside a sports ground or airfield.

All sorts of acoustic barriers to keep the noise out and the peace and quiet in.  All the traffic we have to put up with nowadays makes noise barriers more important that ever for keeping it all under control.
