Impact of Construction Materials Used for HDB Flats on Noise Transmission

5 Mr Gan Thiam Poh asked the Minister for National Development what are the measures which the Ministry has put in place to ensure that the materials used in the construction of new HDB flats meet the standards required to minimise noise transmission between floors and flat units.

The Minister for National Development (Mr Lawrence Wong): Mdm Speaker, HDB buildings are built using reinforced concrete in accordance with the prevailing building codes and industry norms. This ensures that our buildings are structurally safe and suitable for occupancy. While there are no existing regulations or standards on acoustical performance of building structures, the Housing and Development Board (HDB) is mindful of the needs of residents in this regard. Based on our survey, the vast majority of residents and respondents have expressed satisfaction with the noise insulation performance of their unit walls and floors. Nevertheless, HDB is continually looking at practical noise mitigation measures for the comfort and well-being of all residents.

I should also highlight that in the context of our high-density environment, and with HDB flats designed for natural ventilation, it is not possible to completely sound-proof a unit. So, we do need all residents to do their part. Considerate neighbourly behaviour, such as keeping noise levels down, especially at night, will help provide a pleasant living environment for all.
