Abstract
This paper presents a study of noise level generated by the operation of air-conditioning in an amphitheater. Noise level generated by it was too high for the specific activities developed in this enclosure. For noise level reduction in enclosure was identified as constructive solution use a frequency converter. Noise level values recorded ranged according to frequency of the motor. At the same time was studied the influence of the outside temperature on the ambient temperature of the amphitheater.
