Sound insulation level estimation peculiarities
Walls, floor and ceiling conduct sound waves. A sound wave affects the surface and transmits vibrations to it. The wall in the adjacent room plays the role of the dynamic in a loud speaker: its vibrations convert into the sound waves.
Acoustic transmission of ceiling, partition and raised floors.
Various gaps and openings in walls, floor and ceiling also serve as conductor of sound waves. It is important to remember about them because even is a totally isolated wall has a small hole it will transmit the sound to the adjacent room.
Thus the conclusion is evident. For the first thing, it is essential to restrict the transmission of sound waves to the surfaces of the isolated room. Secondly, it is important walls, ceiling and floor do not have any openings or holes.
