Steps that can be taken to control noise pollution include erecting barriers to insulate noise producers, installing materials that absorb sound, dissipating noise-generating vibrations and placing physical breaks between a vibrating object and the hearer. Architectural acoustics use all of these techniques to protect residents from unwanted sound. In addition, roads and airports require special treatment to deaden noise pollution.Know More
As eSchoolToday points out, tested methods for protecting neighborhoods from noise pollution include creating barriers by placing noisy machinery in soundproofed rooms or planting trees along roadways. Urban planning plays a key role in placing noisy industries, airports and major transportation hubs away from residential areas, as well as in regulating smaller sources of noise pollution such as public announcement systems, car horns and noisy vehicles.
Noise pollution from roads can be mitigated through careful design of the road, the materials used, better tire tread design and the erection of road barriers to limit road noise to the roadway itself. In addition, electric and hybrid cars help minimize road noise pollution.
The best ways to control noise pollution from airports focus on building airports away from residential districts, restricting flights to certain hours and redesigning flight paths. In addition, residential soundproofing can help control noise pollution for those living near an airport.Learn more about Human Impact
A rod knock usually sounds like a light, steady pounding noise coming from inside the engine block. It is loudest when the engine is running at higher revolutions per minute, and when the vehicle's speed is steady, neither accelerating nor decelerating.Full Answer >
Heat measures the movement of molecules in an object, while temperature measures the average energy or heat generated by the molecules in an object. The faster the molecules move, the more heat they produce and the higher their temperatures become.Full Answer >
Noise pollution has many adverse affects on humans, including stress-related illnesses, hearing loss, sleep disruption, speech interference and loss of productivity, according to eSchoolToday. Perhaps the most acute problem associated with noise pollution is the hearing loss it can cause after long-term exposure. Affecting the eardrums, noise pollution can cause permanent damage when present for a prolonged period of time.Full Answer >
Sound or noise pollution refers to the excessive noise that interferes with normal activities, potentially leading to a lower quality of life. The main sources of noise pollution include machines and mechanical equipment, fireworks, vehicles, music performances and emergency sirens.Full Answer >
