• Interference with Communication: Noise can make it difficult to hear and understand speech, leading to communication problems.
• Environmental Impact: Noise pollution can disrupt ecosystems and wildlife, affecting their behavior and survival.

Ways to Control Noise

There are various methods to control and reduce noise pollution:

• Soundproofing: Using materials and techniques to reduce the transmission of sound through walls, floors, and ceilings.
• Regulations and Standards: Implementing laws and standards to limit noise levels in different settings, such as residential areas and workplaces.
• Use of Ear Protection: Wearing earplugs or earmuffs in noisy environments to protect the ears from excessive noise.
• Noise Barriers: Constructing physical barriers, such as walls or fences, to block or absorb sound waves.
