Noise pollution is everywhere we go, we can never escape it, but not all noise pollution is bad, it all depends on the level of which the noise is omitted. Safe sounds are measured up to 85dB (decibels), anything above that can have serious effects on your health. Noise pollution can cause not only hearing problems such as tinnitus and hearing loss, but can have an effect on sleep, aggression and stress levels, which in itself has damaging health effects.
High noise levels can have damaging effects even when exposed to the sound for a short amount of time, according to Hearing Loss and Coronary heart disease by S. Rosen and P. Olin during an eight hour period blood pressure can rise by five to ten points, which can rise even more if stressed.
Many people who reside in urban areas where there is a lot of noise pollution (maybe they have an airport situated close by) according to a study undertaken in 2005 approximately pay 4 Euros per decibel per year for noise reduction. However, there is a simpler way to protect your hearing and health when it comes to noise pollution and that is wearing a pair of noise reduction ear plugs. They are cheaper and can be taken everywhere you go, whether you decide to attend a music concert or are travelling.
It is scary how easily our hearing can be damaged, but it is even more reassuring that it can be protected just as easily, if not more so.
