White Noise Problems playing this file? White noise is energy randomly spread across a wide frequency band containing all notes from high to low. It is called "white" noise as it is analogous to "white" light which contains all the colors of the visible spectrum.

Environmental noise Environmental noise is the accumulation of all noise present in a specified environment. The principal sources of environmental noise are surface motor vehicles, aircraft, trains and industrial sources.

Regulation of noise[ edit ] Main article: Noise regulation Certain geographic areas or specific occupations may be at a higher risk of being exposed to constantly high levels of noise; in order to prevent negative health outcomes, regulations may be set. Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government.

Environmental noise is governed by laws and standards which set maximum recommended levels of noise for specific land uses, such as residential areas, areas of outstanding natural beauty, or schools. These standards usually specify measurement using a weighting filtermost often A-weighting.

The following year, OSHA required employers to provide a hearing conservation program to workers exposed to 85 dBA average 8-hour workdays.

Exposure to noise is associated with several negative health outcomes. Depending on duration and level of exposure, noise may cause or increase the likelihood of hearing losshigh blood pressureischemic heart diseasesleep disturbancesinjuriesand even decreased school performance.

Prevention[ edit ] While noise-induced hearing loss is permanent, it is also very preventable. This can be especially important for professionals working in settings with consistent exposure to loud sounds, such as musiciansmusic teachers and sound engineers. Physiological noise is felt subconsciously as the vibrations of the noise sound waves physically interact with the body while psychological noise is perceived as our conscious awareness shifts its attention to that noise.

He argues that any kind of noise could be used as music, as audiences become more familiar with noises caused by technological advancements; noise has become so prominent that pure sound no longer exists.Whether the noise is coming from office machines, chattering co-workers or construction, the effects can lead to an increase in disturbed emotions and a reduction in productivity.

In the present cross-sectional study, 50 workers were selected from a steel company in Fars province, Iran, and exposed to 85, 95, and dB noise levels for 5 . A comparative risk assessment of burden of disease and injury attributable to 67 risk factors and risk factor clusters in 21 regions, – a systematic analysis for the Global Burden of Disease .

Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage.

"Twenty-two million workers are exposed to potentially damaging noise at work each year. Environmental noise is the accumulation of all noise present in a specified environment. The principal sources of environmental noise are surface motor vehicles, aircraft, trains and industrial sources.

These noise sources expose millions of people to noise pollution that creates not only annoyance, but also significant health consequences such as elevated incidence of hearing loss and.
