5. RECOMMENDED GOOD PRACTICES FOR DIFFERENT NOISE SOURCES

The following recommended good practices for different noise sources are for reference purpose only. No guarantee is given to the performance of the application of the recommended practices. The reader is advised to seek professional advice from independent experts in case of doubts or complicated problems.

Noise Source	What effcets the impact	Good Practices to consider
Noise from music, singing and instrument playing	Building design	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
	Volume	Maintain the volume of sound systems at low levels Control by sound limiter
	Doors and windows	Keep doors and windows closed during operation hours Equip doors with self-closing mechanism 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
	Loudspeakers	Avoid placing loudspeakers or TV that direct music or sound to doors or windows of the premises Avoid placing loudspeakers or TV outside the premises
Structural vibrations	Building design	Apply integrated noise mitigation measures e.g. "double" and composite ceiling, composite wall and floating floor design of the premises structure
	Dancing	Apply floating floor and vibration isolator systems
	Loudspeakers	Use anti-vibration pad for floor-standing loudspeakers Use properly designed spring isolator for overhung or wall-mounted loudspeakers
Activities at exposed outside areas	Building design	Locate entrances and exits from the building and outside areas as far from residential properties as possible.
Activities at exposed outside areas	Venue management and friendly reminder to patrons	Restrict or prohibit patrons from access to exposed areas for drinking at all time especially at night. Post notices to advise patrons to be considerate to the neighbour (e.g. no shouting or loud voices)
Fixed plant and machinery	Building design	Locate the plant and machinery away from residential properties as far as possible. Use screening provided by existing building structure, non-sensitive buildings and natural feature as much screening as possible.
Fixed plant and machinery	Ventilation units or beer pumps	Arrange regular maintenance Equip machinery with properly designed integrated noise mitigation measures (e.g. be mounted on anti-vibration mounts and/or provided with an acoustic enclosure or additional screening) where necessary
Cleaning and handling of bottles	Building design	Locate refuse and storage areas away from residential blocks, and shield them.
Cleaning and handling of bottles	General noise	Avoid carrying out during the night or early morning Provide rubber wheeled bins and smooth pathways between the residential properties and store area, to reduce noise while moving bin
