| description | The main aim of the work described in this paper was to design and validate measures to reduce the noise levels in the training center. This training center serves for the practical training of students with the focus in the shaping and machining of engineering products. The reduction of noise in training center was mainly due to the clarity and hearing of the spoken word between the lecturer and the students, as well as to reduce the risk of hearing damage. In order to reduce noise levels, it was proposed to overlap the training center with a roof structure filled with sound absorbing material in two solutions. The noise absorption coefficient of the selected material was determined on the impedance tube. For verification of effectiveness, measurements of equivalent A sound levels were made before and after realization noise reduction measures. Reduction the equivalent A sound pressure levels after the noise reduction measures are between 15.5 dB and 17.5 dB depending on the measuring point and the operating mode. The effectiveness of the implemented measures reaches a good level, as noise has been reduced to the recommended legislative level. |
