Night clubs attracts mass of society and are the entertainment clubs for the people to get relaxed and to enjoy. It ranges from high energy clubs that has loud voices and a place to dance, to casual bars. But night clubs along with the entertainment poses threat to human health in the form of noise related health problems. Due to high volume and lack of noise control procedures, people get affected by different health problems such as aural pain, ear discomfort speech interference; cardiovascular effects; sleep disturbances that may further leads to accidents; decreased physical performance, permanent hearing loss; increased psychological problems.
The average noise levels in night clubs have been measured having the range of 100 dB A-weighted and over. Exposure to the high sound levels depends upon the pattern of attending, and the retention time in the night club The restrictions for a night club to control noise before granting approval are many. However, the most important would be: isolating the night club in the first place, by controlling the sound transmission by constructing the second wall after the original wall. Another restriction is soundproofing, that ultimately not only reduce the sound inside but the night club but additionally, will not create noise cense outside the club.
Furthermore, the acoustic quality within the night club should be maintained by the use of proper equipments and absorbing material. The allocation of equipments should be on the right place and order. Also, the control of noise from the source by using the proper equipment is the most important thing. The application of room treatment is also an important aspect as to reduce the reflective reverberations from the poorly maintained halls. The proper use of acoustic shields and vibration isolators are also important to reduce the noise impacts.
The glass, windows and walls constructed should be sound absorbent rather than sound reflective. Furthermore, it would be advisable to hire a sound and acoustic expert for better implications. Radon, a radioactive gas was discovered in 1900 by Ernest dorn. Uranium and thorium occur naturally in minute and variable quantity in earth crust. They produce a series of daughter products that emits alpha, beta and gamma radiation and radon is one of the daughters. Radon emits alpha rays. In alpha decay, the atomic number changes, so the original (or parent) atoms and the decay-product (or daughter) atoms are different elements and therefore have different chemical properties.
It decays and produces short lived daughters of major concern being the decay products Po218 and Po214 which are solid and exist in equilibrium with radon. We inhaled these particulate daughters along with the air we inhale. It causes significant damage to the delicate inner cells of the bronchioles. It has been known that long term exposure internal exposure of these particles to elevated concentrations increases and individuals risk of developing lung cancer. The short lived alpha particles can damage cellular DNA.
It causes significant damage to the delicate inner cells of the bronchioles. The health risks from the radon in homes where the radon levels are high are much higher than houses where the radon levels are low. The residents living in houses where there are more radon levels are among the leading cause of lung cancer in the world. There are certain techniques by which radon levels can be lowered enough up to level not causing any potential risk. These techniques includes by introducing under-floor extracts and radon mini sumps that creates low pressure.
Inducing air flow through air pumps under the floor is also an effective technique. The damp proof membranes also prevent radon gas from underground. Also an effective technique is that never sit close to the walls and on the empty floor. Also constructing spacious rooms and high ventilation by constructing large windows and ventilated corridors also reduces the effect of radon gas. References: Airtech Environmental Systems. (2010).
