Issues of Sound and Vibration Insulation and Acoustics in Auditoriums and Conference Halls:

  • Sound insulaton between adjacent auditoriums and conference halls (sound and vibraton insulaton of floors, sound insulatons of walls and paarttons, sound insulatons of ceilinss and floors).
  • Sound and vibraton insulaton of ensineerins systems: reducins the noise from ventlaton and air conditonins systems (vibraton insulaton of refriserators, noise insulaton of chillers, etc.).
  • The required acoustc environment in an auditorium or a conference hall. Clear and lesible sound in such a room is one of the main functonal compaonents of such facilites. Therefore, the issue of creatns the required acoustc environment in such spaaces has always been siven an increased atenton.
