Industrial Noise refers to noise that is created in the factories which is jarring and unbearable. Sound becomes noise only it becomes unwanted and when it becomes more than that it is referred to as "noise pollution". Heavy industries like shipbuilding and iron and steel have long been associated with Noise Induced Hearing Loss (NIHL).
Industrial Noise Pollution
This is posing to be a big challenge with very passing day and is a threat to safety and health of the people who are working in the industry and common people as well. It has been scientifically proved that noise more than 85 decibels can cause hearing impairment and does not meet the standards set for healthy working environment. Moreover it can also cause accidents.
The problem has been viewed and analyzed from all the perspectives but the solution probably is not so easy to achieve since there is a lot of contradiction between legislation, guidance and documents. Industrial Noise resulting to noise pollution has many reasons such as industries being close to human habitats which prevents the noise from decaying before it reaches human ear.
Effects of Industrial Noise Pollution
It has already been stated that continuous exposure to noise pollution leads to hearing impairment but it has various other effects as well which are as follows:
- It can result into increase in blood pressure
- Increased stress
- Stomach ulcers
- Sleep disturbance
- Speech Problems
- Dysgraphia, which means writing learning impairment
Industrial Noise adversely affects the workers and they suffer from various health problems as I have listed above. High volume leads to increased adrenaline levels, which leads to the constriction of blood vessels, which normally happens when the individual is tensed, afraid, anxious or extremely happy and excited. The work pressure and the noise pollution both lead to a fairly typical situation, which leads to clinical as well as psychological stress.
The blood pressure, due to the constriction of blood vessels (vasoconstriction), remains high for the major part of the day. The human dislike towards anything that is not pleasant, yet compelling leads to emotional stress and depression which is a term for a quite a severe situation. Statistically there is a rise in the number of workers dying of cardiac arrests and cerebral attacks is on an increase considerably due to industrial noise pollution in railway yards, factories etc.
Some people also suffer from headaches, which decrease their efficiency levels and hamper the quality of their work. That leads to crises in workplace as well as home. Workers are always agitated and excited that result into carelessness. Workers also become fatigued and in some cases over fatigued which should ring the alarm for organizations that want to grow. The worst part of Industrial Noise pollution is it affects the unborn baby in a womb and that too in the early days after conception since the fetus is sensitive to sounds and high decibels affects the growth of its organs.
The problems that the Industrial workers face are sleep disorders and behavioral changes. They experience increased levels of stress. They fail to achieve harmony thus leading to a lot of minor psychological problems, which are too common to be noticed. They are irritated and annoyed; therefore fail to interact with a person around them and this gradually leads them to become "loners".
They withdraw from the society and some in extreme circumstances might have "tremors", speech problems and many other behavioral problems. It is high time that the rules and regulations that are already made should be applied and followed so that we can cope with the ever-increasing problem of noise pollution that is concentrated in the industry environment.
