Any source of sound has the potential to become noise. Sound and noise are terms linked very closely with one another. For organisations who control and manage noise, noise is considered to be distinct from sound. This distinction is based on several key ideas: Noise is unwanted sound; Noise is a subjective term - what one person thinks is noise, another may consider music; Everything we hear is sound - only unwanted sound is noise; and, We cannot measure noise, but we can measure sound.
Noise mapping can be used to avoid making existing situations worse, identifying and prioritising areas for improvement (i.e. noise reduction), and for monitoring changes. Noise mapping can bring benefits in terms of the cost, speed, and quality of land use planning decisions. In addition to assisting development control and forward planning, noise maps can be used to focus and monitor noise abatement schemes. In the future, noise mapping might be integrated with mapping for other pollutants. This could further enhance the speed, quality, and cost of land use planning and make selection of the best option from alternatives more practicable.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
