4.2 Recommended Good Practices to Achieve Best Acoustic Insulation Effect

To tackle noise from coming out through building openings and structures, common good practices are recommended as follows:

  • Install sound trap lobby
  • Increase the sound insulation properties of the walls and ceiling of the structure
  • Adopt good design of windows, doors and ventilation systems to avoid noise leakage
  • Close doors and windows during operation hours
  • Seal acoustically doors and windows, and maintain them in good condition
  • Install acoustically sealed double-glazed noise insulation windows, where necessary
  • Install acoustically sealed double doors which are made of sound insulations or absorption materials, where necessary
  • Avoid placing loudspeakers or TV that direct music or sound to doors or windows of the premises
  • Apply integrated noise mitigation measures e.g. "double" and composite ceiling, composite wall and floating floor design of the premises structure
  • Apply floating floor and vibration isolator systems
  • Use anti-vibration pad for floor-standing loudspeakers
  • Use properly designed spring isolators for overhung or wall-mounted loudspeakers
