Noise pollution is an environmental issue that affects both urban and rural areas. It is defined as excessive, unwanted or disturbing sound that disrupts quality of life and health. Sources include industrial sources like machinery and transportation as well as non-industrial sources like construction and traffic. Noise pollution can cause diseases like high blood pressure, heart attack, and hearing loss. Control methods include reducing noise at the source, using protective equipment, noise control techniques like sound insulation, and legislation to regulate noise levels. Noise pollution is a growing global concern that requires immediate action.
An overview of noise pollution and control is presented, w.r.t. sources, impacts on human life, and mitigation/ control measures. Mining is a hazardous profession, numerous health impact on the miners. Hearing Impairment is one of the major health problems phased on a day to day basis in both open cast (o/c) and underground (u/g) Mines worldwide. But o/c mine is key as it is highly mechanized these days. Thus, this presentation provides basic information w.r.t. noise pollution and control in mines.

Noise Control Stratagies in Reinforced Concrete BuildingsIJRES Journal
This study is aimed at bringing out the salient aspects of building noise control. An analysis has been carried out with respect to the noise transmission as well as the characteristics of noise inside buildings. The key issues on building noise control have been included and discussed. A comprehensive study on building noise and on acoustically divisible spaces has been made. It has been observed that a sound insulation of the order of 30 to 35 dB is possible in a given building. Further, the noise propagation parameters in an exhibition hall have been theoretically estimated. The data so obtained has been compared with actual SPL measurements and recorded. Variations in noise levels observed have been explained. Before the partition is made, the SPL drop is faster inside the building but after the partition the drop falls at the rate of 3dB for doubling the distance. The cost of the acoustically divisible partition wall is found to be very high, but the advantage of this partition seems to be creating acoustically divisible spaces where in one can conduct two programs simultaneously, without any disturbance to each other. Prior to the selection and design of control measures, noise sources must be identified and the noise produced must be carefully evaluated.

An infection is the successful invasion of an organism to body tissue by disease causing agents, their multiplication and the reaction of host tissues to the infectious agents and the toxins they produce.
The Center for Disease Control (CDC) defines Universal Precautions as “a set of precautions designed to prevent transmission of Human Immunodeficiency virus (HIV), Hepatitis B virus (HBV), and other blood borne pathogens when providing first aid health care.”
Hospital Acquired Infection/ Nosocomial Infection also referred to as healthcare-associated infections (HAI), are infection(s) acquired during the process of receiving health care that was not present during the time of admission.
“Health is a state of complete
physical, mental and social well being
and not merely the
absence
of disease or infirmity”.
It means adequate body weight, height and circumference as per age and gender with acceptable level of vision, hearing, locomotion or movements, acceptable levels of pulse rate, blood pressure, respiratory rate, chest circumference, head circumference.

Characteristics of healthy and unhealthy state.pptxRahat Aziz
Healthy state or wellness is a multidimensional concept that incorporates the overall state of an individual's health and well-being across various aspects of life. It goes beyond the absence of illness and disease and focuses on achieving a balanced and fulfilling life.
Unhealthy state or Illness is a state of poor health or a condition in which the body or mind is not functioning normally. It typically involves a departure from the state of well-being and can manifest in various ways, including physical, mental, or emotional symptoms.
The beginnings of psychology are to be found in the curiosity of primitive man about himself and his companions. The development of modern psychology as a science has followed a long and somewhat uncertain course through the centuries. The Greeks were first to study mental illness scientifically and separate the study of the mind from religion.
Wilhelm Wundt is the man most commonly identified as the father of psychology.
Goals of psychology
Describe- Frist goals of psychology are to describe the different ways that organisms behave.
Explain- the cause of behaviour.
Predict- how organisms will behave in certain situations
Control- the fourth goal of psychology is to control an organism’s behaviour.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

9. Effects of noise
Auditory effects:
(i) Auditory fatigue
(ii) Deafness or hearing loss (may be temporary)
(iii)May rupture the tympanic membrane and
cause permanent loss of hearing.
10. Effects of noise continue..
Non-auditory effects:
• Interference with speech
• Annoyance-primarily a psychological response
• Diminished efficiency-inability to concentrate
11. Effects of noise continue..
3.Physiological effects
(i) Rise in blood pressure
(ii) An increase in heart rate and breathing
(iii) Rise in intracranial pressure
(iv) An increase in sweating
12. Effects of noise continue..
Other effects:
(i) General symptoms such as giddiness, nausea,
fatigue.
(ii) Interferes with sleep
(iii) Cause narrowing of pupil
(iv) Cause visual disturbance
(v) Affects night vision.
13. Methods of noise control
1. Noise control at source
Designed acoustic control in new equipment.
Isolation of noisy machines in a corner of the
factory.
Application of mufflers and other sound reducing
materials.
Reduction in the amount of noise transmitted
through the air or building structure.
14. Methods of noise control continue..
2. Control of transmission of noise This may be achieved by -
Building enclosures, and
Covering the room walls with sound absorbing materials.
3. Protection of exposed persons
Regular rotation of workers from noisy areas to comparatively
quiet posts in factories.
Use of ear plugs, ear muffs.
Periodical audiogram check-up.
15. Methods of noise control continue..
4. Legislation
Declaration of noise free area, e.g. hospitals, schools, colleges.
Compensation of workers if they have suffered a loss of ability to
understand speech due to excess noise.
5. Public education
Without people’s participation noise abatement programmed
cannot be succeeded. Public education through all available media
is needed.
It is to be high-lighted that noise abatement is important as a
community hazard.
16. Conclusion
It is evident that noise pollution is a growing
concern globally, affecting urban areas,
workplaces, and even our homes. Therefore, it is
crucial to take immediate action and implement
effective strategies to reduce noise pollution.
