Noise Challenges in Hong Kong Residential Areas
Most of the residences in Hong Kong are high-rise apartments with thin walls and limited space. Common noise problems include:
- External noise : traffic noise, construction sites or airplanes taking off and landing.
- Internal noise : Neighbors talking, the TV, or footsteps upstairs.
- Structure-borne noise : Low-frequency noise generated by pipe vibration or elevator operation.
These challenges require targeted soundproofing materials and technologies, such as acoustic curtains and acoustic doors , to achieve efficient sound absorption and noise protection.
Key technologies for residential sound insulation
Effective residential soundproofing relies on the following techniques:
- Sound absorption : Use sound-absorbing materials to reduce indoor echo, such as ENA sound insulation cotton (NRC=0.3), suitable for walls or ceilings.
- Mass barrier : High-density materials block airborne noise, such as ENA sound insulation blanket NE200 (STC=23), which can be installed on the wall or floor.
- Sealing technology : Ensure that the gaps between doors and windows are sealed, and soundproof windows and doors can effectively prevent noise penetration.
Case sharing: In the residential sound insulation project of the Po Leung Kuk Main Building in Causeway Bay, Ena Acoustic used soundproof curtains and ENA soundproof blanket NE200 to successfully reduce the impact of traffic noise on residents.
