WHAT IS NOISE POLLUTION? What is noise Pollution? Sound is essential to our daily lives‚ but noise is not. Noise is generally used as an unwanted sound‚ or sound which produces unpleasant effects and discomfort on the ears. Sound becomes unwanted when it either interferes with normal activities such as sleeping‚ conversation‚ or disrupts or diminishes one’s quality of life. Not all noise can be called noise pollution. If it does not happen reqularly‚ it may be termed as ’Nuisance’

Noise Pollution When unwanted sound created by human beings hits our ears and disturbs the environment‚ noise pollution is created. Chiefly‚ noise pollution comes from barking dogs‚ loud music‚ vehicles‚ aircraft and rail transport‚ air-conditioners‚ factories‚ amplified music and construction work.Noise‚ by definition‚ is unwanted sound. What is pleasant to some ears may be extremely unpleasant to others‚ depending on a number of factors. The natural environment contains many sources of noise -

Noise Pollution The nature of sound Sound‚ a manifestation of vibration‚ travels in wave patterns through solids‚ liquids and gases. The waves‚ caused by vibration of the molecules‚ follow sine functions‚ typified by the amplitude and wavelength (or frequency) Sound waves of equal amplitude with increasing frequency from top to bottom Reflecting on noise “Noise" derived from "nausea‚" meaning seasickness Noise is among the most pervasive pollutants today Noise is unavoidable for many

Noise pollution is displeasing or excessive noise that may disrupt the activity or balance of human or animal life. The word noise is cognate with the Latin word nauseas‚ which means disgust or discomfort.[1] The source of most outdoor noise worldwide is mainly caused by machines and transportation systems‚ motor vehicles‚ aircrafts‚ and trains.[2][3] Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution‚ since side-by-side industrial and

Noise pollution (or environmental noise) is displeasing human‚ animal or machine-created sound that disrupts the activity or balance of human or animal life. The word noise comes from the Latin word nauseas‚ meaning seasickness. The source of most outdoor noise worldwide is mainly construction and transportation systems‚ including motor vehicle noise‚ aircraft noise and rail noise.[1][2] Poor urban planning may give rise to noise pollution‚ since side-by-side industrial and residential buildings

Environmental Noise Becca Gillett Thursday December 19th 2013 Noise is a prominent part of our society and causes significant damage to our ears as well as increasing a risk of cardiovascular diseases. The field of environmental noise works to study what devices create the most noise and how we can reduce that noise to therefore reduce the harm done to humans. An increase in the intensity of a noise is the increase in the energy in its sound waves‚ and if this energy gets to a certain point

introduction Noise pollution is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused bymachines and transportation systems‚ motor vehicles‚ aircraft‚ and trains.[1][2] Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution‚ since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.

White Noise- Don Dellilo Name Institution Date White Noise White noise is a natural sound that mimics a particular environment to sooth the nerves of adults or even distressed children. The white noise puts them to sleep mainly by drowning other sounds.

This is defined a form of air pollution that is audible unwanted sound that poses a threat to a person’s health
