Investigation of the mechanical vibrations effect on sound insulation and sound transmission properties of the sound absorber cellular materials

The noise generated by the machines in the production area and in the outdoor environment is an important problem for the employees and the people in the environment. Noise can be examined in two main subjects as structure-born and air-born noises. The basic source of structure-born noise is vibration. This noise significantly reduces the productivity of the employees. Various control methods are applied to reduce, control and reduce the impact on people around them. In the energy sector, for example, sheathing and cabin systems and noise control works are carried out. In this thesis, in the first stage, the relationship between vibration level and noise is examined. In the second stage, the noise and vibration characteristics of the energy sector, where the need for noise control is intense, are examined. In the third stage, stone wool material which is used extensively for noise control in these sectors is discussed. The rock wool material was subjected to vibration. The sustainability of acoustic life was investigated during the process of vibration exposure.
