Noise is every unwanted sound, noise appearance (bobbery, murmur, roisterer, banging, speech, etc..) that interferes with work or rest. Physical education is characterized by diversity of content, constant change of intensity, but teaching process is also followed by a large number of students, health and sanitation terms, micro-climate and noise, which are allocated as disturbing factors. This research deals with the origin and the noise level during the implementation of a series of physical education classes in elementary schools in the city of Nis. We assessed the classes of students aged 11 years, who had had sports games for the teaching unit. The obtained results of the noise measurements processed by the up-to-date measuring instruments(sound level meter) and methods indicate that noise occurs in certain degree but does not enter the area of critical values. Noise was measured in the phases of the classes and was registered in the range of 69 to 82 dB with the characteristics of the noise continuous type. In order to lower the level of noise in physical education teaching process certain measures and procedures should be taken: improved discipline of the pupils, organisation and the choice of the methodological forms of work, choice of the requisites in the teaching process, and the use of verbal method in the acoustic halls.
