EPD is well aware of the need for innovative means to mitigate road traffic noise impacts. Through collaborations in research & development as well as project developments. Studies with noise measurement found that the Acoustic Window (AW) were effective in reducing the noise transmitted from the outdoor to the indoor environment while maintaining natural ventilation inside the premises. Adoption of the acoustic windows enables the maintaining of a quiet living environment for residents and reducing the operation of air-conditioning for sustainable living. This webinar will walk you through its innovative journey and share with you updated information on AW and the experience of its applications in planning cases. The webinar will also cover a recently issued Practice Note on Application of Acoustic Window (Baffle Type) in Planning Residential Developments against Road Traffic Noise Impact. To enable participants to have first-hand information, 4D VR demonstration of AW will be conducted to let participants have a visual and audio experience of AW’s noise reduction effectiveness.

Programme Highlights
Accommodating 7 million population in 1,100 km2 area, Hong Kong is a truly densely populated city where keeping traffic noise at bay is a challenge in planning new housing development. Due to high demands of housing development and lack of suitable sites, more and more sites housing blocks are put next to heavily trafficked road. As results, traditional noise mitigation measures, e.g. building setback, noise barrier, internal layout design, etc. are found insufficient in meeting L10(1hr) 70 dB(A, )the local noise planning criteria.

Environmental Protection Department is well aware of the need of innovative means to mitigate road traffic noise impacts. Through collaborations in research & development as well as project development, various kinds of Innovative Noise Mitigation Designs (INMDs), including acoustic windows, have been studied, tested, developed and applied in public and private residential development in the past few years. These INMDs were demonstrated effective in reducing the noise transmitted from outdoor to indoor environment while maintaining the required ventilation inside the premises. Tests conducted for acoustic windows show their effectiveness of reducing 6-8 dB(A), the in-out noise level difference under conventional setting and acoustic setting.

INMDs have been adopted in engineering feasibility studies of new town developments as early as 2010s. They were also adopted in Schedule 3 Environmental Impact Assessment studies (e.g. Housing Sites in Yuen Long South, Hung Shui Kiu New Development Area, Comprehensive Residential and Commercial Development atop Siu Ho Wan Depot, etc.) to mitigate road traffic noise problem for strategic planning in order to expedite the residential development potential in proximity to major roads.

A 4D VR tool has been developed for the acoustic window to enable project managers, architects, designers, practitioners, etc. to visualize the potential results of adopting acoustic window so as to facilitate their adoption in building designs. A demonstration of the 4D VR tool will be conducted at the seminar to enable participants to have visual and audio experience of noise reduction effectiveness of acoustic window.
