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
