Noise pollution
Noise pollution occurs when unwanted or disruptive sounds negatively impact daily life or health. It is caused mainly by transportation systems in urban areas as well as construction and industrial activities. The World Health Organization recognizes noise pollution as a major threat to human well-being due to its links to higher blood pressure, stress, sleep disruption, and hearing loss. Solutions include planting trees near loud areas, maintaining vehicles and machinery, installing soundproofing in buildings, and enacting regulations on loud speakers.
Noise pollution
Thermal pollution occurs when industrial and power plant effluents increase the temperature of surrounding water bodies. This warmer water holds less dissolved oxygen and increases the metabolism of aquatic organisms. Effects include reduced oxygen levels harming fish and amphibians, interference with reproduction cycles, increased diseases and invasions by destructive warm-water species. Control methods involve cooling heated water in ponds or towers before returning it to natural systems.
Noise pollution and solid waste management
The document discusses noise pollution and its causes, effects, and solutions. It states that unwanted sound that disrupts quality of life is called noise pollution. Transportation, construction, and industrial activities are major sources of noise pollution in urban areas. Noise pollution can damage health physically and psychologically, causing issues like high blood pressure, hearing loss, and mental health problems. Some solutions proposed include planting trees near noise sources, regular vehicle maintenance, soundproofing buildings, and locating industries away from residential areas.
Effects Of Noise Pollution On Aquatic Animals
Noise pollution from ship engines and sonar systems affects aquatic animals by making it difficult for them to communicate, find food, and avoid hazards. It can also interrupt their natural habitats if sources of noise such as construction sites or concerts are near bodies of water. Excessive noise raises animals' heart rates, harms their metabolism, and prevents them from detecting prey or communicating with each other because they only hear human noise instead of sounds they emit. Noise pollution disturbs animals' environments and impacts their ability to focus in the same way that loud band practice outside a classroom would interfere with students' attention spans. Steps like installing barriers and limiting loud vehicles can help prevent noise pollution, as can simply placing soundproofing materials around sources of

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 Pollution
This presentation is useful to all the students who studied and get information about noise pollution. It gives a basic knowledge about noise pollution and also useful for them who study in environmental engineering or civil engineering or science.
Noise pollution
Sound is produced by vibrating objects which causes changes in air pressure that travel as sound waves. Noise is unwanted sound that can have negative physiological or psychological effects. Common sources of noise pollution include traffic, industrial machinery, defense equipment, and household appliances. Prolonged exposure to loud noise can cause hearing loss and health issues like increased stress. Noise pollution also negatively impacts communication and work efficiency.
Noise pollution
This document discusses noise pollution, including its sources, measurements, classifications, and effects on health. It defines noise as sound that causes irritation and outlines key parameters of sound including frequency, pressure, and intensity. Noise is measured in decibels on a logarithmic scale relative to a reference level. Noise can be classified as transport noise from vehicles, occupational noise from machinery, or neighborhood noise from loud music or appliances. Prolonged exposure to noise over 90dB can cause temporary or permanent hearing loss. Noise pollution has also been linked to psychological and pathological effects like increased stress, fatigue, and changes in heart rate or blood pressure.
Social issue
Noise pollution is an unwanted sound that negatively impacts recipients. It is a serious problem caused by industrialization and has become a global issue. Sources of noise pollution include transportation, construction, industries, and domestic appliances. Prolonged exposure to loud noise can cause hearing loss, stress, sleep disturbances, and other health issues like increased blood pressure. It also negatively impacts wildlife and structures. Solutions include reducing noise at its source through insulation, limiting loud sounds in public through laws, education, and planting noise-absorbing trees.
Noise Control Stratagies in Reinforced Concrete Buildings
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.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
