Sound waves are mechanical waves in the longitudinal direction that propagate in a variety of solid or gaseous media. The medium for the propagation of sound waves is the atmospheric environment. This medium consists of particles which are influenced by environmental conditions. The purpose of this paper is to show that atmospheric temperature can have an effect on the speed of propagation of sound waves. The measurements on which the study is based were made in the same areas and at the same time intervals, under the same atmospheric conditions, during periods of high and low temperature. The results confirm that the speed of sound waves is influenced by the parameters of the environment in which they propagate. The speed of sound is faster when temperatures are higher.
