Noise Pollution and Its Impacts on Humans.pptx

This in-depth presentation reveals the critical problem of noise pollution and its enormous impact on health and the environment. trace the sources and forms of noise-pollution, and fathom its detrimental effects on human health, such as stress, loss of hearing ability, and sleep disorders. Again, find out the ecological consequences: habitat disruption for wildlife and marine life. It also addresses the current mitigation strategies and possible solutions to do something to avoid noise pollution for a cleaner, healthier, and more sustainable environment in which to live. This is ideal for students, environmental lovers, and all those who wish to learn about it and fight against this often-ignored environmental hazard.

3. 1. Understanding the noise pollution Sound that is unwanted or that disrupts the activity or balance of human or animal life is called as noise. When there is lot of noise in the environment, it is termed as noise pollution.

4. 1. Understanding the noise pollution World Health Organization stated that “Noise must be recognized as a major threat to human well-being”

5. 1. Understanding the noise pollution Noise is typically measured in units called decibels (dB). Decibels represent the intensity or volume of sound.

6. 1. Understanding the noise pollution Some examples of noisy things and their approximate dB values: *Whispering*: 20 dB *Normal conversation*: 60-70 dB *Busy city traffic*: 70-85 dB *Motorcycle*: 80-100 dB *Rock concert*: 100-120 dB *Jackhammer*: 100-120 dB *Jet engine at takeoff*: 120-140 dB

7. 1. Understanding the noise pollution It's important to note that these values can vary depending on factors such as distance from the source, environmental conditions, and the specific model or type of equipment. Additionally, prolonged exposure to noise levels above 85 dB can potentially cause hearing damage.

8. 2. Sources of Noise Pollution Transportation systems are the main source of noise pollution in urban areas. Construction of buildings, highways, and streets cause a lot of noise, due to the usage of air compressors, bulldozers, loaders, dump trucks, and pavement breakers.

9. 2. Sources of Noise Pollution Industrial noise also adds to the already unfavorable state of noise pollution. Loud speakers, plumbing, boilers, generators, air conditioners, fans, and vacuum cleaners add to the existing noise pollution.

10. 3. Effects of Noise Pollution on Human Health Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noise demonstrate significantly reduced hearing sensitivity than their non-exposed peers.

11. 3. Effects of Noise Pollution on Human Health Unwanted noise can damage physiological and psychological health. Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.

12. 3. Effects of Noise Pollution on Human Health High noise levels can contribute to cardiovascular effects and exposure to moderately high levels during a single eight hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress and vasoconstriction leading to the increased blood pressure.

13. 4. Regulations and Standards The first step in abating the emissions of pollutants into the ambient environment—whether air pollutants, water pollutants, or noise, etc.—is the setting of standards designed to protect the health and welfare of humans and other living things.

14. 4. Regulations and Standards Figure 1 gives a graphical representation of the basic noise pollution standards, applicable to five noise impact zones and specified for daytime (0700 to 2200) and nighttime (2200 to0700). The standards have three dimensions: noise level, frequency distribution, and temporal distribution. The two dimensional mensuration unit dBA (sound pressure level in decibels as measured on the "A" scale of a sound level meter)sums the sound pressure levels at all frequencies weighed ac-cording to their intensity as sensed by the average human ear.

15. 5. Mitigating Noise Pollution Planting bushes and trees in and around sound generating sources is an effective solution for noise pollution. Regular servicing and tuning of automobiles can effectively reduce the noise pollution.

16. 5. Mitigating Noise Pollution Buildings can be designed with suitable noise absorbing material for the walls, windows, and ceilings. Workers should be provided with equipment's such as ear plugs and earmuffs for hearing protection .

17. 5. Mitigating Noise Pollution Similar to automobiles, lubrication of the machinery and servicing should be done to minimize noise generation. Soundproof doors and windows can be installed to block unwanted noise from outside.

18. 5. Mitigating Noise Pollution Regulations should be imposed to restrict the usage of play loudspeakers in crowded areas and public places. Factories and industries should be located far from the residential areas

19. 6. What can Electronic Engineers do? Noise Reduction in Electronic Devices: Design devices with built-in noise reduction features like shielding, filtering, and low-noise circuit design. Quieter Technologies: Develop quieter technologies by optimizing designs, using sound-absorbing materials, and incorporating vibration isolation.

20. 6. What can Electronic Engineers do? Active Noise Control (ANC): Implement ANC systems using electronic signal processing to cancel out unwanted noise in real-time. Environmental Monitoring: Develop noise monitoring systems for accurate assessment of noise levels and identification of sources.

21. 6. What can Electronic Engineers do? Noise-Reducing Materials: Research and develop materials with noise-reducing properties for construction, transportation, and industrial applications. Regulatory Compliance: Ensure products comply with noise regulations through testing, certification, and ongoing compliance management.

22. 7. Conclusion In summary, noise pollution poses significant threats to human health and the environment. Through understanding its sources, effects, and regulatory frameworks, we can implement effective mitigation strategies. As electronic engineers, our contributions are vital in developing innovative solutions. Together, let's prioritize noise reduction efforts to create healthier and more peaceful communities. We should prevent exposure of noise in working environment to save our precious life.
