Investigation The Weather Effects on The Sound Absorption Coefficients in Cinjar City
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 4, Issue 1
Abstract
In this work , the absorption coefficients A? had determined for different acoustic source by the air atmosphere for one day in Cinjar city, based on an analytical method which employed on several empirical equations that taking in consideration the various meteorological conditions in which the climate elements changed in additional to frequencies sources .The results shows the atmospheric absorption is sensitive to the composition of air , particularly to the wide varying concentration of water vapor and temperature where the air temperature play and frequency variation are dominate that controlling the values of A? .
