ARCHITECTURAL ACOUSTICS

Room design strives to enhance acoustical comfort, bounce, speech intelligibility or privacy in closed spaces where communication is the primary activity (room acoustics). Isolating the room from intruding noise and vibrations (building acoustics) provides a calm environment and enhances quality of life and comfort, at home as well as at work.

Public Spaces

When the acoustics of a room is designed right, the sound, music or speech, is perceived by everyone in the assistance, without rising the volume.  Consequently, chances of disturbing the neighbourhood  are minimised without giving up on acoustic performance.
 

Open-plan Offices

Noise and background noise level can be controlled to achieve privacy, good hearing conditions and acoustical comfort for adjacent open offices.   It is then possible to provide a productive pleasing workplace environment where several persons can work together or communicate in the same room without interfering with each other.
 

 
Install:

• Acoustical ceiling tiles with a high absorption coefficient

• Composite partitions that are high enough to block sound transmission

• An electronic sound masking system to control background noise

• Sound-absorbing products to stop sound reflection

• Noisy equipment as far as practical from office areas
   

Nothing is more annoying than hearing the neighbour music or conversation! To prevent room-to-room airborne noise transmission, diagnostic tests shall be conducted to identify, measure and analyse the source of noise and its propagation path.  Then, acoustical products shall be carefully selected and installed to contain noise at its source or to intercept noise on its route to the receiver.  The installation of an electronic sound masking device also reduces intrusion of sounds from adjacent areas or mechanical equipment.
 

Structure-borne noise resulting from footsteps, moving of furniture, building mechanical systems (HVAC), elevator, can travel through ductworks, walls, floors and ceilings.  It then radiates somewhere else in the building in the form of airborne noise, disturbing occupants, even if there are located far from the vibration sources.

N.B. Vibrations may also be introduced by rotating mechanical equipment (vibration control) or outdoor sources (outdoor vibrations)
 

• Room acoustical performance

• Effective sound and vibration insulation of the apartment from :
          - adjacent apartments
          - the outdoor

• HVAC and piping systems

• The installation of a floating floor to absorb impact noise
