Speech On Noise Pollution

Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn’t need to be tangible. Things as simple as light, sound and temperature can be considered pollutants when introduced artificially into an environment. Look at any ecosystem and there could be multiple forms of contamination-streams full of toxic chemicals from industrial processes, rivers overloaded with nutrients from farms, trash blowing away from landfills, city skies coverd in smog. Even landscapes that appear pristine can experience the effects of pollution sources located hundreds or thousands of miles

Noise pollution is often an issue but it is not given enough attention. Of late, this aspect is discussed in earnest when the sound level is increasing from day to day. The rapid development of the country to the status of industrialized countries which caused the number of vehicles on the road rose is one of the main sound sources in our country. Construction projects that use a lot of construction machinery and more airports are also among the other contributors to noise pollution. In the employment sector, the sound level of safety should be ensured to prevent workers suffering from hearing problems. For now, most of the industrial sector in the country is more labor-oriented than in developed countries. In this regard the operation of the equipment in the building is likely to expose workers to the risk of hearing damage. Noise measurements are also important to assess the sources, effects and appropriate control

At this stage vibration sound waves vibrate more quickly than the noise gland. Vibration wave is about 3 dB only. For example the noise fluctuations occur when someone is talking, and the engine sound is not muted. Shock impulse noise is more intensity in a shorter period. Typically, this level of vibration wave will peak and decline rapidly. At this level of intensity noise exceeds 80 dB sound waves will then decline rapidly. But the intensity is still showing a high level due to loud noise will affect the length of the vibration. Noise alternating occur alternately. It is produced when the noise becomes slower and stronger in the short term. An example: when someone is sawing wood, vibration will occur when the saw is moving and the vibration does not occur when the saw wood stopped. During the saw being pulled intensity will rise at a certain rate and decreased when the saw is thrust. The effects of noise pollution on humans can be divided into physiological effects and psychological effects. involve physiological effects of hearing loss and the response to a state of anxiety and psychological effects caused by noise pollution that disturbs communication between people, disturb sleep and consequently mental destabilize and disrupt the mental process of thinking and focusing hard to do.
