What The World’s Noisiest Cities Tell Us About Excessive Noise

Depending on which study you find, the noisiest cities in the world tend to be found in cities that are densely populated with high volumes of traffic with poor planning which exacerbates the effects of noise on their populations.

The worst city in the world for noise pollution is Guangzhou in China and the effects on residents are really quite frightening. The average hearing loss in proportion to age in the city stands at nearly 17 years. In Delhi where noise pollution levels are not too far behind the hearing loss is 20 years.

In Western Europe, however, the effects of noise on the local population is in some cases considerably less at 10 years in proportion to age. Vienna tops the list in Europe followed by Zurich and Hamburg.

However Barcelona and Paris have the misfortune of appearing in the worlds top 10 worst cities for noise pollution at 7th and 9th respectively.

While studies have focused on actual hearing loss, the more subtle underlying effects are still a fertile area of study where links to dementia, cardiovascular disease and depression are only just coming to light.

Of course the best way to deal with noise if you live in a city is to insulate your property to keep it out. If you want to find out more about sound insulation for your home of business then contact us 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.
