Negative Effects of Sound Pollution

Every sound in a structure can be traced back to its acoustical roots. Creaky door hinges are rusty, too tight or in need of a good oiling. Floorboards squeaking or groaning are either incorrectly fastened or not plumb or true.

As for ominous loud ticking clocks, either you’ve been watching too many scary movies or you have very thin walls with no acoustical insulation and thin drywall layers. This too can be easily solved with a variety of wall types from traditional staggered stud to new high-performance ultra-thin ZR walls.

Unintended Negative Effects of Noises

The impact of subway noise on surrounding neighbourhoods shows that increased cardiovascular disease is related to sleep disorders caused by rail noise in urban areas. While most spooky sounds are low frequency noise, subways do create a wider variety of noises than wind turbines or deep footsteps, thereby having a wider and deeper range of effects. These are similar to having a spooky bad dream including, but not limited to:

Increased heart rate
Lack of deep REM sleep
Increased blood pressure
Elevated anxiety and stress levels

Last, but not least, is our favorite means of long-distance travel, airplanes. Because of new engine designs, noise from aircraft is getting better with each generation. Nevertheless, there is still a significant impact on local environments and the people living there. Similar to subway noise, physiological issues include:

Cardiovascular issues
Cognitive issues in children
Elevated anxiety
Decreased attention spans due to sleep deprivation.

The effect of noise pollution on health and wellbeing

Noise pollution above a certain level is not only disruptive and irritating, it can also be very damaging to health and wellbeing.

We’ve all experienced annoyance due to loud or persistent noises before. But did you know that noise exposure also causes physiological effects within our bodies?

Physiological effects of noise pollution

When noise exceeds a certain level, it can cause constriction of blood vessels and tightening of muscles, this then increases heart rate and blood pressure.

In fact, a study by Dr Yutong Samuel Cai, an epidemiologist at Imperial College London, found that long-term exposure to traffic noise affects our blood biochemistry, over and above the effects of exhaust fumes.

Over time and with prolonged exposure to the noise, these affects can leave us vulnerable to some serious health conditions.

Research has linked long-term exposure to high levels of noise pollution with a variety of serious health problems including:

High blood pressure
Cardiovascular disease
Heart attack
Stroke
Type 2 Diabetes
Coronary heart disease

According to the World Health Organisation at least 1m healthy life-years are lost every year in western European countries because of environmental noise.

Short-term effects of noise pollution

As well as long-term health problems, in the short-term, exposure to noise pollution can leave us feeling stressed and disrupt our sleep.

Getting enough good quality sleep is extremely important to health and wellbeing, and disrupted sleep can cause symptoms like fatigue, inability to concentrate, and low performance levels.

In children, this can also reduce their cognitive performance and ability to learn.

The Challenges Of Insulating A Barn Conversion

Barn conversions can make the most attractive homes but they can also be challenging projects not only from a build point of view but also when it comes to thermal efficiency.

Nowadays thermal efficiency is a much more important consideration than it has been in the past. Property owners must now include Energy Performance Certificates when advertising a property for rent or sale and this obviously influences the decision to rent or buy a property. Few people are going to pay their hard earned cash to live in a poorly insulated property or one that scores poorly on its EPC.

So one of the main challenges when converting a barn is making sure it is conforms to modern building and energy efficiency standards. Insulating high vaulted ceilings can be difficult as attractive as they are, but there is a way to cut the cost and achieve those all important efficiency scores. That is to use spray foam insulation.

This can be applied quickly and easily and dramatically cuts down the time it takes to apply insulation so that your barn conversion ticks all the boxes for your prospective buyers. If you require more information on insulating your property give us a call today.

Hidden Noise Hazards That May Be Lurking in Your Home

Have you ever been irritated by the noise of a vacuum cleaner or the rumbling of a washing machine? You may be surprised to hear that these noises can sometimes be comparable to the noise you would hear on a factory floor or building site.

When you consider that even low levels of noise can have an impact on health and wellbeing over time, then insulating against noise can do much more than create a more peaceful environment.

According to studies carried out on how noise impacts on our health, anything over 85 decibels can damage hearing. Of course most people are going to be wearing ear protection if noise is regularly exceeding these levels but with lower level noise, the effects can be more subtle and accumulate over time.

The World Health Organisation’s studies on noise found that 40% of the people they surveyed were regularly exposed to the kind of noise levels found in noisy offices. A noisy office will typically see noise exceeding 50dB.

The noisiest appliances in the home most likely to reach and exceed this noise level include vacuum cleaners with some emitting more than 80dB of noise. Washing machines can also contribute 50dB or more. A food processor will see noise levels reach 90dB and even the flush of a toilet will come in at 85dB.

DIY and garden maintenance are the main culprits when it comes to excessive noise. The 120dB noise level from hammering a nail is equivalent to that of a chainsaw while an electric drill comes in at 95dB.
