دراسة التلوث الضوضائي في المعهد التقني-النجف

Abstract EN

The noisiness consider one of contaminants that affect the Civilian Society institutions especially the teaching institutions due to its negative effect on the performance of the teaching staff, students and workers in those institutions, during (2014-2015) one of the teaching institutions which is (Al Najaf teaching institute) has been chose to measure the noisiness and compare the results with the allowing references no., the noise was measured in three different working times (8:30-10:30 am, 10:30-12:30 am, 12:30-2:30 pm) in internal sites, which are technical college and technical institute, (the technical institute which include library, management department and technical department) and external sites (major interns and green areas) by using sound level meter sample (GM 1351).

In this research we choose three interior spaces (main hall, lecture halls, lecturers room) in earth floor and (main hall, laboratories, or lecturers room) in first floor of management department and technical department and (main hall, lecture hall, laboratories) in the second floor for (tourist, law management) department and (main hall, laboratories, lecturer room) in earth floor of technical college.

The biggest value of noise was measured in each internal and external space included in this study, then calculated the total average of noise level in internal and external sites in one study day.

The results of the study showed that highest noise level was in management department (tourist, law management) which reach (76.6 dB), while the lowest noise level in the library was (62.7 dB) that’s for interior sites.

For exterior sites the highest noise level was in the green areas reaching (70.3 dB), while the lowest noise was in major entrance "information place" reaching (66.0 dB).

The results denoted that the total average of noise level in all internal and external sites was highest than that accepted levels of noise agreed by Earth Pollution Association (EPA) that allowed only (30-40 dB) in academic institutions, while (45-55 dB) for out sides.

That’s for, the high unacceptable noise average is unpleasant in academic institutions because it resulted in many complications to both students, cultural, and health trouble, nervousness, inability of concentration with study, etc., so that its important to found solves by educational institutes to reduce the risk of this problem (noisiness) in our institutes for the benefit of our higher education and our health.
