Pollution

Pollution is when poisonous substances occur in many form.There are many type of pollution, but now I only focus on one type, the type that people rarely mention, sound pollution.
Sound pollution, and noise pollution,  is phenomenal intensity and different frequencies, arranged without order, causing discomfort to the listener, affecting the work and relaxing the people. It is also possible that the sound emitted at the wrong time, sound output intensity exceeds human tolerance levels. If noise exceeds the permitted level will impact directly on the health and life of humans.

According to scientists, the intensity noise 50dB degrade performance, especially the mental work. Noise to 70dB increase breathing rate and heartbeat, increased body temperature and blood pressure, affects the digestive activity and reduce operational interest. 90dB noise causes fatigue, insomnia, auditory functional damage, loss of balance the body and nervous breakdown.

And what affects and sound pollution give you?

Several studies recently rated noise pollution topped the list of air pollutants harmful to human health. Sound pollution is harmful to both adults and children. Children are exposed to continuous noise will have difficulties with learning. Especially the ability to complete assignments and learn the language very much affected.

Sound pollution also affect human sleep. If a person lacks sleep, the whole body will be affected negatively. That is inevitable. Regular exposure to noise will make people with tinnitus (always hear the buzzer sound inside the ear). This situation adversely impacts the nervous system and your health.

These studies show that noise pollution is also a cause of high blood pressure and cause heart problems. This type of pollution is becoming increasingly dangerous for humans in the present and the future. Noise pollution also affects human memory and other cognitive abilities. It particularly affects the ability to remember the lesson of the children.

One of the solution for this is to surround produces some by shell sound-proofing noise sources. For example do shell soundproof generator, fan or compressor ... noise. Sound equipment housings often have multiple layers. Outside the 2ly thick ribbed steel stiffener; inner layer of porous material with small pores interconnected used 50 mm thick glass wool, followed by lining and corrugated layers hole to protect porous material layer.
