Sound Pollution effect on Pulse Rate, of Selected Students at the Science and Engineering Workshop
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 3
Abstract
Sound which is a mechanical disturbance that generate waves through an elastic media is characterized by compression and rarefaction, within an audible frequency of 20-20,000Hz. It is a function of industrial and anthropogenic activities but a silent killer that affect human being, mentally and increase molecular task through the endocrine systems, which will increase the bio-oxygen demand and an increase pulse rate to cope with the demand. The study is to evaluate the impact of varying noise level on workshop staff and students using sphygmomanometer. The base is science and engineering workshop at N 04.53.4 E 54.26.3. The range is ‘x’ ≤ 90bBA, ‘y’≥110 dBA, control ‘C’50-60dBA,the sound source is a multi-media set of 0 Dba to 160 dBA which is varied as the need arises. The results indicate a significant difference for ‘y’ ≥ 110 dBA with a p. value of 0.003 less than a level of significant of 0.05 but showed no significant difference at ‘x’ ≤90dBA in the pulse rate evaluation. The recommendation is the use of personal protective wear and enforcement of standards where applicable
