Question

Which of the following is NOT an example of noise pollution control measure?

• A. Soundproofing buildings
• B. Increasing industrial activities in residential areas
• C. Enforcing noise level regulations
• D. Using noise barriers along highways

Hint:

(¤) \textbf{Noise Pollution Control Measures} aim to reduce noise levels or exposure.
(¥) Examples include:
(¦) Engineering controls: Soundproofing, noise barriers, quieter machinery.
(§) Administrative/Legal controls: Noise level regulations, zoning (separating noisy sources from sensitive areas).
(¨) Planning controls: Buffer zones, careful site planning.
(©) Increasing noise-generating activities (like industry) in noise-sensitive areas (like residential zones) is a source of noise pollution, not a control measure.

Answer 1

The Correct Option is B

Noise pollution control measures are actions taken to reduce or mitigate the harmful effects of excessive or unwanted sound (noise). Let's analyze the options:
( ) (a) Soundproofing buildings: This involves using materials and construction techniques to reduce sound transmission into or out of buildings (e.g., insulating walls, double-glazed windows). This is a direct measure to control noise exposure within buildings. So, it IS a noise pollution control measure.
(¡) (b) Increasing industrial activities in residential areas: This would generally increase noise pollution in residential areas, as industrial activities are often sources of significant noise. Locating noisy industries away from residential zones (through land use planning/zoning) is a noise control measure. So, increasing industrial activities *in* residential areas is NOT a control measure; it's a cause of noise pollution.
(¢) (c) Enforcing noise level regulations: Governments and local authorities often set permissible noise level standards for different zones (residential, commercial, industrial) and times (day, night). Enforcing these regulations (e.g., through monitoring, penalties for violations) is a key administrative and legal measure for noise pollution control. So, it IS a noise pollution control measure.
(£) (d) Using noise barriers along highways: Noise barriers (walls or berms) are physical structures built alongside busy highways or railways to block or reduce the transmission of traffic noise to adjacent sensitive areas like residential neighborhoods. This is a common engineering measure for noise control. So, it IS a noise pollution control measure. The question asks which option is NOT an example of a noise pollution control measure. Option (b), "Increasing industrial activities in residential areas," would exacerbate noise pollution, not control it. \[ \boxed{\text{Increasing industrial activities in residential areas}} \]
