Özet:

In order to reduce acoustic noise in residential, industrial as well as other premises, this research examined the interaction between the acoustic field of fixed sources (fans) and the insulating housing used for acoustic noise transformation. For this purpose, a model of acoustic field and heterogeneous mechanical system interaction was designed and tested to adequately reflect the actual processes. The results showed that the designed theoretical model allows to predict changes of the acoustic field in the installation environment. The absolute error of the values calculated by the model by using experimentally determined sound pressure level loss values did not exceed 2.5 dB when compared to the experimental values.
