NOISE CONTROL Meaning and
Definition
-
Noise control is the process of limiting, reducing, or mitigating unwanted sound or noise levels in various environments. It seeks to minimize the adverse effects of excessive noise on human health, well-being, and quality of life. The primary goal of noise control is to create a more comfortable and conducive acoustic environment by regulating the levels and characteristics of noise.
Effective noise control involves understanding and addressing the intensity, frequency, duration, and source of the noise. It employs various measures such as engineering controls, administrative controls, and personal protective equipment to achieve desired noise reduction or elimination.
Engineering controls include implementing noise barrier walls, soundproofing materials, acoustic enclosures, and vibration isolators to isolate or contain noise sources. Additionally, noise control can be achieved through modifying machinery or equipment to reduce noise emissions or through implementing proper maintenance practices.
Administrative controls involve implementing policies, regulations, and guidelines to control noise exposure in workplaces, public spaces, and residential areas. This may include zoning regulations, noise ordinances, and ensuring compliance with established noise standards.
Personal protective equipment comprises individual devices such as earplugs or earmuffs that individuals can use to protect themselves from excessive noise exposure.
Overall, noise control is important for maintaining a healthy and comfortable acoustic environment, protecting people from hearing damage, ensuring peace and quiet in residential areas, improving concentration and productivity in workplaces, and enhancing the overall quality of life.
Etymology of NOISE CONTROL
The word "noise" originated from the Middle English word "noise", which was derived from Old French "noise", meaning "uproar, brawl, riot". This can be traced back to the Latin word "nausia", meaning "sea-sickness, discomfort".
The term "control" comes from the Latin word "controllare", which means "to check, regulate, restrain". It is a combination of the prefix "con-" meaning "together" and "trollare", meaning "to move, to control".
Combining these two origins, "noise control" refers to regulating or managing the level, intensity, or impact of unwanted sounds or disturbances in the environment.
