International Noise Awareness Day
International Noise Awareness Day is a global campaign, founded in 1996 by the Center for Hearing and Communication (CHC), aiming to raise awareness of the effects of noise on the welfare and health of people. Noise affects people in many ways, but only deafness and annoyance receive actual interest from the general public. Worldwide, people are called upon to take part via various actions on this occasion: open days on hearing from acousticians, lectures in public health departments, universities and schools, panels of experts, noise level measuring actions, and readings. The day is commemorated on the last Wednesday of April of each year. Activities aimed at creating a focus not only on noise, but also on means of reducing noise levels, are organized in a number of countries all over the world, including Brazil, Chile, Germany, Italy, Spain and the United States. In recent years, there have been related events initiated in Asia, including Singapore and Australia. See also * ...

Advocacy Group
Advocacy groups, also known as lobby groups, interest groups, special interest groups, pressure groups, or public associations, use various forms of advocacy or lobbying to influence public opinion and ultimately public policy. They play an important role in the development of political and social systems. Motives for action may be based on Politics, political, Economy, economic, religious, morality, moral, commerce, commercial or common good-based positions. Groups Methods used by advocacy groups, use varied methods to try to achieve their aims, including lobbying, media campaigns, consciousness raising, awareness raising publicity stunts, Opinion poll, polls, research, and policy briefings. Some groups are supported or backed by powerful business or political interests and exert considerable influence on the political process, while others have few or no such resources. Some have developed into important social, and political institutions or social movements. Some powerful advo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Noise
Noise is sound, chiefly unwanted, unintentional, or harmful sound considered unpleasant, loud, or disruptive to mental or hearing faculties. From a physics standpoint, there is no distinction between noise and desired sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound. Acoustic noise is any sound in the acoustic domain, either deliberate (e.g., music or speech) or unintended. In contrast, noise in electronics may not be audible to the human ear and may require instruments for detection. In audio engineering, noise can refer to the unwanted residual electronic noise signal that gives rise to acoustic noise heard as a hiss. This signal noise is commonly measured using A-weighting or ITU-R 468 weighting. In experimental sciences, noise can refer to any random fluctuations of data that hinders perception of a signal. Measurement Sound is measured based on the amplitude and frequency of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Deafness
Deafness has varying definitions in cultural and medical contexts. In medical contexts, the meaning of deafness is hearing loss that precludes a person from understanding spoken language, an audiological condition. In this context it is written with a lower case ''d''. It later came to be used in a cultural context to refer to those who primarily communicate with a deafness aid or through sign language regardless of hearing ability, often capitalized as ''Deaf'' and referred to as "big D Deaf" in speech and sign. The two definitions overlap but are not identical, as hearing loss includes cases that are not severe enough to impact spoken language comprehension, while cultural Deafness includes hearing people who use sign language, such as children of deaf adults. Medical context In a medical context, deafness is defined as a degree of hearing difficulties such that a person is unable to understand speech, even in the presence of amplification. In profound deafness, eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Acoustician
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, craft, science and technology have prov ...

Public Health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The ''public'' can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of ''health'' takes into account physical, psychological, and Well-being, social well-being, among other factors.What is the WHO definition of health? from the Preamble to the Constitution of WHO as adopted by the Internationa ...

Ambient Noise Level
In atmospheric sounding and noise pollution, ambient noise level (sometimes called background noise level, reference sound level, or room noise level) is the background sound pressure level at a given location, normally specified as a reference level to study a new intrusive sound source. Ambient sound levels are often measured in order to map sound conditions over a spatial regime to understand their variation with locale. In this case the product of the investigation is a sound level contour map. Alternatively ambient noise levels may be measured to provide a reference point for analyzing an intrusive sound to a given environment. For example, sometimes aircraft noise is studied by measuring ambient sound without presence of any overflights, and then studying the noise addition by measurement or computer simulation of overflight events. Or roadway noise is measured as ambient sound, prior to introducing a hypothetical noise barrier intended to reduce that ambient nois ...

Environmental Noise
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and Sport, recreational activities. Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity. The effects in humans of exposure to environmental noise may vary from emotional to physiological and psychological. Noise at low levels is not necessarily harmful. Environmental noise can also convey a sense of liveliness in an area, which can be desirable. The adverse effects of noise exposure (i.e. noise pollution) could include: interference with speech or other 'desired' sounds, annoyance, sleep disturbance, anxiety, hearing damage and stress-related cardiovascular health problems. As a result, environmental noise is studied, regulated, and monitored by many governments and institutions around the world. This creates a number of ...

Safe Listening
Safe listening is a Conceptual framework, framework for health promotion actions to ensure that sound-related recreational activities (such as Concert, concerts, nightclubs, and listening to music, broadcasts, or podcasts) do not pose a risk to hearing. While research shows that repeated exposures to any loud sounds can cause Hearing loss, hearing disorders and other health effects, safe listening applies specifically to voluntary listening through personal listening systems, personal sound amplification products (PSAPs), or at entertainment venues and events. Safe listening promotes strategies to prevent negative effects, including hearing loss, tinnitus, and hyperacusis. While safe listening does not address exposure to unwanted sounds (which are termed Noise pollution, noise) – for example, at work or from other noisy hobbies – it is an essential part of a comprehensive approach to total hearing health. The risk of negative health effects from sound exposures (be it no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
World Hearing Day
World Hearing Day is a campaign held each year by Office of Prevention of Blindness and Deafness of the World Health Organization (WHO). Activities take place across the globe and an event is hosted at the World Health Organization in Geneva annually on March 3. The campaign's objectives are to share information and promote actions towards the prevention of hearing loss and improved hearing care. Any individual or organization can participate in various ways, by sharing campaign materials and organizing outreach actions. Examples are provided in the World Hearing Day annual activitiereports For participation to be recognized, one needs to register and report on their activit The first event was held in 2015. Before then it was known as International Ear Care Day. Each year, the WHO selects a theme, develops educational materials, and makes these freely available in several languages. It also coordinates and reports on events around the globe. 2025 For 2025, the theme of the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

April Observances
April is the fourth month of the year in the Gregorian and Julian calendars. Its length is 30 days. April is commonly associated with the season of spring in the Northern Hemisphere, and autumn in the Southern Hemisphere, where it is the seasonal equivalent to October in the Northern Hemisphere and vice versa. History The Romans gave this month the Latin name '' Aprilis''"April" in '' Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 1, p. 497. but the derivation of this name is uncertain. The traditional etymology is from the verb ''aperire'', "to open", in allusion to its being the season when trees and flowers begin to "open", which is supported by comparison with the modern Greek use of άνοιξη (''ánixi'') (opening) for spring. Since some of the Roman months were named in honor of divinities, and as April was sacred to the goddess Venus, her Veneralia being held on the first day, it has been suggested that Aprilis was originally her ...
