Effects Of A Noisy Environment

NOISY ENVIRONMENT AFFECTING THE DEVELOPMENT OF LANGUAGE increasing levels of road noise have been invading villages and there were no provisions to limit this damage. The traffic management has made the heavy traffic rather than reduced to a few streets you see scattered throughout the city. This previously quiet areas have been considerable deterioration in its external environment. On the other hand, many educational facilities have been improperly locating near large sources of noise or they, as in the case of roads, could have discoursed with paths too close to some schools. Protection against noise area has not been able to implement, largely because the criteria for protection for this type of pollution are not part of urban planning.

For years known harmful effects caused by noise. The damage caused by the auditory pathway are perhaps the best known, but especially at the level of audibility and intelligibility of communications is where it shows more clearly the effects of noise. The investigations of the last two decades have highlighted the impact of noise in the school. The disruption of the intelligibility of oral communication is particularly serious when it comes to the training of students and mental development of young generations. The noisy environment affects the development of language, and the acquisition of reading in all early childhood and primary school are the two periods for intellectual capital. The main effects are: loss of meaning of the content of the teaching of teachers, their vocal fatigue, reduced attention of students, mistakes in the intelligibility of words and even whole sentences. Understanding the word in a classroom is a function of background noise.

Usually, in the workplace, speech is not distorted in both the background noise level is less than 10 dB (A) sound level emitted voice. The maximum ambient noise in a busy classroom should not exceed 55 dB (A), since for a much higher level of educational message is inaudible. One of the basic aspects of the current overview about this type of pollution is the absence of legislation specifically limiting outside noise, regardless of their origin, the various land use or at least the most sensitive acoustic point of view (hospitals, schools, etc.) rules as a basis and criteria in the preparation of planning, acting and preventive level. Urban planning as a tool for the rational use of a scarce natural resource such as urban land is also one of the best tools to prevent environmental damage arising from the noise. Although the first and main control method to prevent noise degradation of schools is to proceed through urban zoning to prevent incompatible land uses, there is yet another significant means of reducing noise pollution, especially in indoor environments (classrooms) which is the derivative of the intervention in the design of buildings. Finally, it is necessary to act on the centers built by sound rehabilitation. Because, as the poet said: “The wind brought a voice / that came from far away. / I wanted to understand what he said / but I could not understand. ” Francisco Arias Solis live in the world when we love.
