The Necessity Of Drilling Noise Control

By Jocelyn Davidson


Offshore drilling is incredibly hazardous to the environment. In addition to the obvious oil spills, sonic pollution is a very damaging issue that requires drilling noise control. Although oil or gas leaks are the most well-known problems, sound pollution has equally hazardous effects on marine life. When disturbed by foreign sonic waves, marine life is unable to properly communicate, locate their food, and navigate themselves. It's reported that beaching of whales and dolphins might be a direct results of this.

This issue has been quite well researched in recent past. On top of damage to marine life, it's found that human hearing is negatively affected by any type of sound pollution as well. Whether the loud sound is constant or syncopated, it will result in hearing loss over time. This accounts for noise from appliances at home, factory machines, and even music.

Humans should realize how damaging noise pollution is to their hearing. Even though damage can certainly be temporary, constant damage like this will eventually degrade your hearing abilities. Sound at 80 decibels, although 70 is enough to be comprehended as loud sound, will start to be hazardous to hearing and can result in temporary impairment. When this gets to 100, however, the damage to hearing is permanent.

Excessive or exposure to loud sound will influence cognitive function as well. Reading can become more difficult, as well as comprehension and problem solving. On top of cognitive impairment, loud sound can also be a large distraction, especially in the workplace. Unfortunately, children are also highly affected by excessive sound. Researchers have compared children who attended school in noisy areas to ones who learned in quiet settings, and found loud sound was negatively correlated.

Noise pollution will eventually damage the heart as well. Research has been done, and it shows that blood pressure rises due to impairment of arteries and blood flow. Heart rates will also increase, especially in children. When these children have constantly high heart rates, they can eventually develop cardiovascular diseases.

High levels of pollution will be detrimental to your sleeping patterns. Obviously, loud noises can distract you from sleeping at night. This prevents people from feeling well-rested, and leaves them irritable and very uncomfortable during the day. On top of this, you will lose energy and experience a bit of fatigue as well. Your work performance will be highly affected because of this. Your social life can also be affected from lack of sleep. Since you are irritable, you might project your feelings to others, and end up offending them.

An environment of 50 to 60 decibels will be noticeably noisy to people. This will prevent people from talking to each other coherently. When you're in this situation, it's very easy to misunderstand what each other is saying, or simply not hear any speech at all.

The stress you experience due to all these noise pollution consequences can lead to mental health issues. Depending on the amount of stress, you can even develop aggressive tendencies. Other less extreme cases can still lead to some problems like headaches, anxiety or tension, and emotional issues.
