FRAMEWORK SOUNDSCAPE DESIGN
1. Localization of functions
2. Reduction of unwanted sounds
3. Introduction of wanted sounds
Sonic compatibility
Noise buffer, source reduction
Water, vegetation, birds, activities
Planing
Ecological barrier
Refuge
New vs existing functions
Topographical change
Stimulation
Natural sounds - Improved mood & cognitive performance Decrease pain & heart rate SOUNDSCAPE

ANALYSIS TOPOGRAPHY
Low point Cliff Opportunity: + Cliff as soundwall + Low point create another layer of ecology
SOUNDSCAPE
Constraints: - Retain vs remain deep port - Flooding issue - Flat ground cause overly wind exposure
CHENGHAO OUYANG
ANALYSIS GEOGRAPHY
Disturbed Terrain Hawkesbury sandstone Opportunity: + Sandstone as important groundwater reservoir to support ecology growth + Sandstone area indicates the original Glebe Island SOUNDSCAPE
Constraints: - Massive concrete cause lack of biophony sound - Unstable & immature sandstone

DESIGN PROCESS
ACCESSIBILITY & LIVABILITY
Stone fill to create aquaic habitat & different water sound SOUNDSCAPE
More habitat for biophony sound
Keep axis & open view to Sydney harbour
Keep waterfront promenade
Room-like soundscape space provide choices CHENGHAO OUYANG
PHASES
Phase 1: PHYTOREMEDIATION & INSTALLATION
Phase 2: GROWTH
Phase 3: REFUGE
OBJECTIVES: + Keep the advantage of deep port, appropriately position the industrial area + Keep the advantage of open view to Sydney harbour bridge + Create habitat to bring biophony sound e.g. birds, frogs, leaves + Minimize noise spreading by vegetation buffer & topographical manipulation + Create diverse selection of soundscape that caters to different people + Celebrate heritage buildings by soften hard surface & encourage engagement + Increase ability of noise absorption by vegetation + Control the noise intrusions by visitors, gradually open access during habitat growth SOUNDSCAPE
